Description

Connection method and device of wearable device

Technical Field

The application relates to the technical field of electronics, in particular to a method and equipment for connecting wearable equipment.

Background

With the advancement of technology, wearable devices (such as smart watches, sport bracelets, etc.) are increasingly used, and functions are also increasingly enriched, for example, body-feeling fitness can be performed by connecting the wearable device with a terminal device. Specifically, the wearable device can be connected with terminal devices such as a mobile phone, a large-screen device or a tablet personal computer, the wearable device collects motion data of a user and transmits the motion data to the terminal device, and the terminal device displays or feeds back actions of the user according to the motion data.

Generally, a wearable device can only establish connection with a terminal device, and if the connection between the wearable device and other terminal devices is to be realized, a user needs to perform a relatively complex operation. Taking the smart watch as an example, under the condition that the smart watch is connected with the mobile phone, if a user needs to connect the smart watch with large screen equipment (such as a smart television), the connection between the smart watch and the mobile phone needs to be disconnected firstly, and the binding relationship between the smart watch and the mobile phone is released, so that the smart watch can enter a paired state. And then, the user controls the large-screen device to search the intelligent watch, and inputs a connection instruction through the large-screen device to instruct the large-screen device to establish connection with the intelligent watch. This process is cumbersome and the user experience is poor.

Disclosure of Invention

The application provides a connection method and equipment of wearable equipment, which can simplify user operation and improve user experience.

In a first aspect, the application provides a connection method of a wearable device, the method is executed by the wearable device, the wearable device and a first terminal device have established a first connection, the first connection is a short-range wireless communication connection based on a first communication protocol, the method comprises the steps of receiving notification information sent by the first terminal device, the notification information being used for indicating surrounding second terminal devices with a trust relationship with the first terminal device, the notification information being received after the wearable device enters a preset geographic area, sending a first broadcast message to surrounding devices in response to the notification information, the first broadcast message being used for the surrounding devices to find the wearable device, displaying a first interface according to the notification information, the first interface comprising a first control, responding to a connection instruction input by a user through clicking the first control, establishing a second connection with the second terminal device, the second connection being a short-range wireless communication connection based on the second communication protocol, or responding to a first request message sent by the second terminal device, establishing a third connection with the second terminal device, the third connection being a short-range wireless communication connection based on the third communication protocol.

Optionally, the first terminal device may be, for example, a mobile phone, a tablet computer, or the like. The second terminal device may be, for example, a large screen device. The wearable device may be, for example, a smart watch, a sports bracelet, or the like.

Optionally, the first communication protocol, the second communication protocol, and the third wireless communication protocol may be one of a bluetooth (blue) protocol, a Matter protocol, a Zigbee (Zigbee) protocol, a Wi-Fi (WIRELESS FIDELITY) protocol, a Thread protocol, or a Mesh (Mesh) protocol, respectively. The first communication protocol and the second communication protocol may be the same protocol or different protocols. Alternatively, the first communication protocol and the third communication protocol may be the same protocol or different protocols.

Optionally, the notification information may carry device information of the second terminal device. The device information of the second terminal device includes, but is not limited to, a media access control (MEDIA ACCESS control, MAC) address. The wearable device may display the first interface according to device information of the second terminal device in the notification information. The first interface may include device information of the second terminal device. In addition, in the case that the notification information carries the device information of the second terminal device, the wearable device may directionally send the discoverable broadcast to the second terminal device according to the device information of the second terminal device, that is, the discoverable broadcast carries the device information (such as the MAC address) of the second terminal device. The smart watch directionally transmits discoverable broadcast to the second terminal equipment, and after other equipment receives the discoverable broadcast, determines that the MAC address carried in the broadcast message is inconsistent with the self MAC address, discards the discoverable broadcast message and does not continue to analyze, so that the interference of the wearable equipment to other surrounding equipment can be reduced, the power consumption of the surrounding equipment is saved, and the user experience is improved.

Optionally, the first request message is used to request a connection to be established with the wearable device. When the third communication protocol is a bluetooth protocol, the first request message may be a pairing request.

In general, when a wearable device has established a connection with a terminal device, the wearable device is in a paired state, and in consideration of the security of user information, the wearable device does not send discoverable broadcast to the surroundings any more, and only after the user disconnects the connection and releases the binding relationship between the connection, the wearable device is triggered to send discoverable broadcast to the surroundings again. In the method provided by the first aspect of the present application, under the condition that the first terminal device and the wearable device have established bluetooth connection, the second terminal device having a trust relationship with the first terminal device in the current scene is obtained by receiving the notification information sent by the first terminal device. Under the scene, the wearable device does not break the binding relation with the first terminal device, and the connection with the second terminal device is re-established without affecting the safety of the user information, so that the wearable device sends discoverable broadcast to surrounding devices, and the wearable device can be scanned and discovered by the wearable device. And then, the user operates the second terminal device or the wearable device side, so that the second terminal device and the wearable device are connected in a short-distance wireless communication mode. That is, in this embodiment, when the wearable device has established the first connection with the first terminal device, the wearable device may send the discoverable broadcast to the surroundings without performing operations of disconnecting and unbinding by the user, so that the second connection or the third connection with the second terminal device may be established, the user operation is simplified, the user experience is improved, and the security of the second connection or the third connection established between the wearable device and the second terminal device is high. In addition, in the embodiment, the first interface is displayed according to the notification information, so that the user can trigger to connect the second terminal device based on the input instruction of the first interface, the user does not need to execute the operation of scanning to find the second terminal device on the wearable device side, the user operation is further simplified, and the user experience is improved.

In a possible implementation, the method further comprises automatically disconnecting the physical link with the first terminal device before establishing the connection with the second terminal device.

That is, before "establishing the second connection with the second terminal device", the method further includes automatically disconnecting the physical link with the first terminal device (i.e., the physical link in the first connection) in response to a connection instruction input by the user by clicking the first control. Or before the third connection is established with the second terminal device, the method further comprises automatically disconnecting the physical link with the first terminal device in response to the first request message sent by the second terminal device.

In the implementation mode, the wearable device receives the notification information sent by the first terminal device, so that the current application scene can be determined as that the wearable device is connected with the first terminal device, trusted devices exist in the current surrounding environment, and the trusted devices are the second terminal device. In this scenario, if the wearable device receives a connection instruction that indicates that the user establishes a connection with the second terminal device, or receives a first request message (for example, a pairing request) of the second terminal device, it may be confirmed that the connection between the wearable device and the second terminal device does not affect the security of the user information. Therefore, the wearable device can automatically disconnect the connection with the first terminal device without displaying an interface for inquiring the user or manual operation by the user, and then establish the connection with the second terminal device. Therefore, the short-distance wireless communication connection of the wearable device is switched from the first terminal device to the second terminal device, and the user does not need to execute related operations of disconnection and unbinding, so that the user operation is simplified, and the user experience is further improved. On the other hand, in such a scenario, the wearable device may confirm that the security of the user information is not affected even if the wearable device does not unbind from the first terminal device. Therefore, the wearable device can only disconnect the physical link with the first terminal device, so that when the subsequent wearable device is reconnected with the first terminal device, the establishment phase (for example, the pairing phase) of the logic link is not required to be re-entered, the related operation (for example, the pairing confirmation operation) for establishing the logic link is not required to be executed by the user, the execution programs of the wearable device and the first terminal device are saved, the user operation is simplified, and the user experience is improved.

Moreover, after determining the current application scenario, the wearable device only establishes a data transmission channel with the second terminal device.

For example, in general, in this scenario, the probability that the user connects the wearable device in the second terminal device is relatively high, so that the second terminal device may pop up the information interface of the wearable device after determining the current application scenario according to the first information, remind the user whether to connect, etc., so as to facilitate the user operation and improve the user experience.

For a better understanding of embodiments of the present application, terms or concepts that may be referred to in the embodiments are explained below.

1. Connection

The connection in the embodiment of the application mainly refers to short-distance wireless communication connection. The communication protocol of the short-range wireless communication connection may be one of bluetooth (blue) protocol, matter protocol, zigbee (Zigbee) protocol, wireless fidelity (WIRELESS FIDELITY, wi-Fi) protocol, thread protocol, or Mesh (Mesh) protocol. In the embodiment of the application, a short-distance wireless communication connection (bluetooth connection for short) based on a bluetooth protocol is mainly taken as an example for explanation.

2. Bluetooth device

The bluetooth device refers to a module or a device for implementing a bluetooth connection in an electronic device. Bluetooth devices are largely divided into classical bluetooth (classic bluetooth) devices, bluetooth low energy (bluetooth low energy, BLE) devices (or referred to as bluetooth low energy devices, BLE devices for short) and dual mode bluetooth devices. Among other things, classical bluetooth devices include Basic Rate (BR) bluetooth devices/enhanced rate (ENHANCED DATA RATE, EDR) bluetooth devices, (HIGH SPEED, HS) bluetooth devices, etc. A dual mode bluetooth device is a bluetooth device that integrates a controller for both a classical bluetooth device and a low energy bluetooth device.

3. Transmission channel for Bluetooth connection

Taking a classical bluetooth device as an example, a bluetooth connection may include one or more profile (profile) transmission channels, to name a few:

3.1 HFP channel

English of HFP is called HANDS FREE profile, chinese is called hands-free profile. HTP defines two roles, an Audio Gateway (AG) and a hands-free component (HF), to provide a remote wireless control and voice connection between the audio gateway and hands-free device over a bluetooth connection. The audio gateway may be a mobile phone, such as a mobile phone. In short, based on the HFP channel, the bluetooth device can realize functions of controlling telephone (i.e., call), such as answering, hanging up, refusing to answer, voice dialing, and the like.

3.2, A2DP channel

English of A2DP is called advanced audio distribution profile, chinese is called advanced audio distribution configuration file. A2DP specifies protocol stack software and methods of use for transmitting high quality audio data using bluetooth unsynchronized transmission channels. Based on the A2DP channel, the Bluetooth devices can mutually transmit high-quality audio data.

3.3, SPP channel

English of SPP is called serial port profile, chinese is called serial port configuration file. SPP defines the Bluetooth device requirements required to set up an analog serial cable connection between two peer devices using a serial emulation protocol (radio frequency communication, RFCOMM), expressed in terms of the services provided to the application and the functions and procedures required to define interoperability between Bluetooth devices. In short, based on SPP channels, bluetooth devices are capable of point-to-point data transmission capabilities.

It should be noted that the profile of bluetooth is also various, and is not listed here. The Bluetooth device can select the required profile according to the requirement, and establish a corresponding profile channel.

4. Trust ring and trusted device

And the two or more terminal devices establish trust relationship through trusted authentication to form a trust ring. In other words, a plurality of devices have a trust relationship with each other, and it is understood that the plurality of devices form a trust ring.

The terminal devices can be trusted by any one of the following methods, a trust relationship is established, and a trust ring is formed, namely 1) the same account number is respectively logged in two or more terminal devices, the terminal devices under the same account number are mutually trusted, then the two or more electronic devices form a trust ring, for example, two mobile phones of the same user, or mobile phones, tablet computers, notebook computers and the like of the same user can be trusted by logging in the account number of the user, and the trust relationship is established, so that a trust ring is formed. 2) And 3) the two or more electronic devices perform the trusted authentication through logging in the cloud, establish the trust relationship and form the trust ring. It will be appreciated that the above several ways are for illustration only and are not to be construed as limiting the application in any way.

Terminal equipment in the trust ring forms a local area network through near field communication, and data can be synchronized through the local area network, so that the coordination of the equipment is realized.

A certain terminal device within a trust ring may be referred to as a trusted device of other devices. That is, by trusted authentication, a terminal device having a trust relationship is referred to as a trusted device. For example, a mobile phone, a tablet computer, and a notebook computer form a trust ring, and the tablet computer and the mobile phone may be referred to as trusted devices, i.e., the tablet computer is a trusted device of the mobile phone, and the mobile phone is also a trusted device of the tablet computer.

The application scenario of the embodiment of the present application is described below.

Wearable devices such as smart watches, sports bracelets, smart glasses, smart headbands, headphones, and the like are increasingly used in people's lives. The wearable device can be connected with the terminal device in a pairing mode, and related functions are achieved. Taking wearable equipment as an intelligent watch and terminal equipment as a mobile phone as an example, the intelligent watch can be connected with the mobile phone in a pairing way, so that the intelligent watch can answer an incoming call on the mobile phone, or data of the intelligent watch can be uploaded to the mobile phone.

After the wearable equipment and the terminal equipment are connected in a pairing mode, a binding relation between the wearable equipment and the terminal equipment can be automatically established, so that encryption authentication can be conveniently carried out in the next connection, and the link is encrypted. The binding relationship is to store information such as a pairing key (also referred to as a link key) of the peer device. However, in the case where the wearable device is bound to the terminal device, the terminal device can acquire various information of the wearable device, including account information, privacy information, and the like of the user. Therefore, in view of security of user information, in general, a wearable device can establish a connection with only one terminal device. If the wearable device is connected with one terminal device at present, when connection with other terminal devices is needed, the wearable device is required to be disconnected with the current terminal device through the approval of a user, the binding relation with the terminal device is released, and the wearable device is paired with the other terminal devices after entering a paired state. Here, the unbinding relationship is also called as unbinding peer-to-peer, and means that information such as a pairing key with the bound device is deleted. Unbinding may be triggered by clicking on a unpaired control, deleting a device control, or connecting a new device control in the wearable device or terminal device, etc. The following description is made in connection with an application scenario.

Fig. 1 is a schematic application scenario diagram of an example of a connection method of a wearable device according to an embodiment of the present application. As shown in fig. 1 (a), the smart watch of the current user has established a connection with the mobile phone. If the user needs to connect the smart watch with the large screen device to perform body-sensing exercise through the large screen device, the user needs to disconnect the smart watch from the mobile phone first and release the binding relationship between the smart watch and the mobile phone, as shown in the diagram (b) in fig. 1. The smart watch then establishes a connection with the large screen device, as shown in figure 1 (c).

After the intelligent watch is connected with the large-screen device, a user can perform body-sensing body-building through the large-screen device. Somatosensory exercise is also known as artificial intelligence (ARTIFICIAL INTELLIGENCE, AI) exercise or AI exercise, meaning exercise based on somatosensory technology. Somatosensory technology refers to the fact that a user does not need to use complex control equipment, but directly interacts with surrounding devices or environments through limb actions. Specifically, in the body-building process, the wearable device collects motion data of a user through sensors such as a gravity sensor and a gyroscope, and transmits the motion data to the large-screen device based on connection with the large-screen device. A motion Application (APP) in the large screen device displays or feeds back actions of the user according to the motion data, and the like. In one embodiment, after the user disconnects the smart watch from the mobile phone, an application scenario of somatosensory exercise through the large screen device may be as shown in fig. 2.

Optionally, the user may disconnect from the smart watch and unbind the smart watch by operating the smart watch, or disconnect from the smart watch by operating the smart watch and unbind the smart watch. Referring to fig. 3, this embodiment is illustrated by taking an example of disconnecting and unbinding the smart watch by operating the mobile phone. As shown in fig. 3 (a), a user may click on a card 302 of a smart watch (shown as smart watch a) in a device interface 301 in an exercise APP (e.g., exercise health). In response to the user's click, the handset displays the information interface 303 of the smart watch a, as shown in fig. 3 (b). A selection control 304 is included in the interface. The user clicks the select control 304, the tab 305 is displayed in the interface, and the tab 305 includes a delete device control 306, as shown in figure 3 (c). The user clicks the delete device control 306 and a card 307 is displayed in the interface for asking the user whether to delete the device, as shown in figure 3 (d). Included in the card 307 is a determination control 308. After the user clicks the determine control 308, the handset disconnects and unbundles from the smart watch.

And then, the user can initiate pairing connection by operating the intelligent watch or the large-screen device and scanning the discovery device, so that the intelligent watch or the large-screen device and the large-screen device establish Bluetooth connection. Fig. 4 is a schematic diagram illustrating a process of establishing a bluetooth connection between a smart watch and a large-screen device according to an embodiment of the present application. The description will be given taking as an example that the device is found by operating a large screen device scan, and the pairing connection is initiated. As shown in fig. 4 (a), in case that both the large screen device and the smart watch are opened bluetooth, the user can open the sports APP in the large screen device and enter the main interface 401 of the sports APP. The user may select the device control 402 in the main interface 401 via the remote control and display the device interface 403 in the large screen device, as shown in fig. 4 (b). The device interface 403 includes an add device card 404, and the user selects the add device card 404 via the remote controller, and the large screen device starts scanning the surrounding bluetooth devices, and displays an add device interface 405, as shown in fig. 4 (c). The large screen device scans for a certain period of time to find out the intelligent watch (shown as an intelligent watch a), an information card 406 of the intelligent watch is displayed in the interface, and a connection control 407 is included in the information card 406 of the intelligent watch. The user selects the connection control 407 through the remote control, and the large screen device establishes a physical link with the smart watch.

Thereafter, the large screen device displays a confirm pairing interface 408 asking the user if he confirms pairing with the smart watch. A popup window 409 may be included in the confirm pairing interface 408, with a confirm control 410 and a cancel control 411 included in the popup window 409, as shown in fig. 4 (d).

When the user clicks the confirmation control 410, the large screen device initiates a pairing request to the smart watch, and the handset displays a first pairing interface 412, as shown in fig. 4 (e).

After the large-screen device initiates the pairing request, the intelligent watch displays a pairing request interface. Illustratively, the pairing request interface of the smart watch may include an accept pairing control 502 in the pairing request interface 501 as shown in 501 in fig. 5 (a). The user clicks the accept pairing control 502 and the large screen device starts pairing with the smart watch, which displays a third pairing interface 503, as shown in figure 5 (b). At the same time, the handset displays a second pairing interface 413, as shown in fig. 4 (f). After a period of time, the large-screen device and the intelligent watch are paired, and connection is established. After the connection is established, the interface between the large screen device and the smart watch may be as shown in fig. 1 (c).

It should be noted that fig. 4 and fig. 5 are only examples, and in practical application, the bluetooth connection between the large-screen device and the smart watch may be established through other operation manners, for example, the selection control 304 in the device interface 403 in fig. 4 (b) may be selected through the remote controller, so as to trigger the large-screen device to scan surrounding bluetooth devices.

As can be seen from the embodiments shown in fig. 1 to fig. 5, when the wearable device establishes a connection with one terminal device, if other devices need to be connected, a user needs to disconnect the connection with the current terminal device and unbind the connection through multiple steps, so that the wearable device enters a mateable state, and then can establish a connection with the other terminal devices, which is complicated and complicated in process and poor in user experience.

In view of this, the embodiment of the application provides a connection method of a wearable device, which can simplify the connection process of the wearable device and a terminal device and improve user experience.

The method for connecting the wearable device provided by the embodiment of the application relates to the wearable device, a first terminal device, a second terminal device, a server and the like. The wearable device can be a sports bracelet, a sports foot ring, a smart watch, a smart wristband, smart glasses, a smart headband, an earphone and the like, and the embodiment of the application does not limit the specific type of the wearable device.

Alternatively, the first terminal device and the second terminal device may be large-screen devices, mobile phones, tablet computers, vehicle-mounted devices, augmented reality (augmented reality, AR)/Virtual Reality (VR) devices, notebook computers, ultra-mobile personal computer (UMPC), netbooks, personal Digital Assistants (PDA) and other electronic devices with short-range wireless communication functions, and Application (APP) may be installed in the first terminal device and the second terminal device.

The following embodiments of the present application specifically describe a connection method of a wearable device provided by the embodiments of the present application by taking a wearable device as an intelligent watch, a first terminal device as a mobile phone, a second terminal device as a large screen device, and bluetooth connection as an example, and combining with a drawing and an application scenario.

In order to facilitate understanding of the solution of this embodiment, a brief description will be first given of a procedure of establishing a bluetooth connection between a wearable device and a terminal device. Taking device a and device B as examples, one of the device a and the device B is a wearable device, and the other is a terminal device. The process comprises the following steps:

1) Transmitting discoverable broadcasts

At least one of device a and device B may actively transmit a discoverable broadcast (also referred to as a broadcast packet or broadcast message) at intervals so that the device can be discovered by other devices. The following description will take an example in which the device a transmits a discoverable broadcast to the surroundings. Typically, device a will not transmit a discoverable broadcast to the surroundings until it is in a pairable state. When the device a is in the paired state, the device a no longer establishes a connection with other devices in view of the security of the user information, and thus the device a does not transmit a discoverable broadcast to the surroundings.

2) Scan discovery

After receiving the discoverable broadcast sent by device a, the surrounding device (e.g., device B) may initiate a scan request to device a to obtain more device information of device a, such as device name, device type, etc. After receiving the scanning request, the device A sends a scanning response packet to the device B for response. The scan response packet may include device information of device a. In this case, device B is the connection initiator, i.e. the master device, and device a is the connection receiver, i.e. the slave device. The device receiving the scan request also needs to send a scan response packet to answer.

Taking the example that the device B initiates the scan request to the device a, the device a sends a scan response packet to the device B after receiving the scan request. And after the equipment B receives the scanning response packet, displaying the equipment information of the equipment A in an interface of the equipment B.

It should be noted that, in general, in a case where the device a has established a connection with one device (for example, the device C), the device a no longer establishes a connection with another device in view of security of user information, and thus the device a no longer transmits a discoverable broadcast to the surroundings, and cannot be scanned for discovery by another device (for example, the device B).

3) Establishing a physical link

After the scan discovery is completed, device a establishes a physical link with device B in response to a connection instruction from the user. Optionally, the physical links may include advanced communication links (advanced communication link, ACL), SCO links, and the like. When a user inputs an instruction to establish a connection with device a in the interface of device B (e.g., clicks on a connection control corresponding to device a), device B establishes a physical link with device B in response to the connection instruction.

3) Pairing

After the physical link is established, the device A and the device B enter a pairing stage. Specifically, the device a sends a pairing request to the device B, or the device B sends a pairing request to the device a, and both enter a pairing phase. The entering of the pairing phase can be triggered by a user input instruction or can be triggered automatically by the equipment, namely, after the establishment of the physical link is completed, the pairing phase is automatically entered.

The pairing phase is essentially the process by which device a negotiates with device B to determine the encryption key. The pairing phase may include several procedures of pairing feature exchange (pairing feature exchange), link authentication, key distribution, and binding.

Pairing feature exchange, namely, the requirement (authentication requirements) for authentication related to the exchange of the two parties (the device A and the device B), the man-machine interaction capability (IO capabilities) of the exchange of the two parties and the like.

Link authentication device a initiates a link authentication request to device B or device B to device a. And if the opposite end receives the pairing request, performing link authentication on the equipment A and the equipment B.

Key assignment device a and device B generate mating keys based on random numbers, pin codes, media access control (MEDIA ACCESS control, MAC) addresses, etc. The mating key may include a long-term key (LTK), among others. The MAC is also called a MAC address.

Binding, namely, the device A and the device B store LTKs, and a binding relationship is established between the device A and the device B. After the binding relationship between the device A and the device B is established, if reconnection is performed again, the pairing stage can be skipped, and the LTK can be directly used for encryption.

4) Establishing profile channels

After pairing is completed, device a and device B establish a profile channel (also referred to as a profile connection) based on the required profile.

It should be noted that, when the device a and the device B complete pairing and binding, and do not unbind (the stored key data is not emptied), and the subsequent device a and the device B are connected, the device a and the device B do not pair and bind any more, so that a physical link can be directly established, a profile channel can be established, and bluetooth connection can be realized.

The following describes a detailed procedure of the connection method of the wearable device provided by the embodiment of the application.

Scene one:

In this embodiment, when the smart watch and the mobile phone are connected by bluetooth, the mobile phone may enter a preset geofence (Geo-fencing), and when a trusted device exists around the mobile phone, the smart watch and the trusted device are connected by bluetooth, and the user does not need to disconnect the smart watch and the mobile phone and also does not need to disconnect the connection between the smart watch and the mobile phone. The following is a detailed description with reference to the accompanying drawings.

Fig. 6 is a schematic flow chart of an example of a method for connecting a wearable device according to an embodiment of the present application, as shown in fig. 6, where the method includes:

s101, under the condition that a Bluetooth connection (also called a first connection) is established between the smart watch and the mobile phone, the mobile phone determines that the mobile phone enters a target geofence according to information of at least one preset geofence and device information in a trust ring, and trusted large-screen devices exist in the target geofence.

The preset geofence is information characterizing a preset geographic area. Geofencing, a new application of location-based services (location based services, LBS), is to enclose a virtual geographic boundary with a virtual fence. When the handset moves from outside the geofence to inside the geofence (i.e., enters the geofence) or from inside the geofence to outside the geofence (i.e., leaves the geofence), the corresponding service is triggered. For example, the electronic device enters a geofence of a high-voltage line, and the corresponding management system may send a notification or alert to the electronic device.

The target geofence is any one of at least one preset geofence. Alternatively, the mobile phone may preset and store information of one or more geofences, where the user may connect the mobile phone with the large screen device at the same time. For example, the preset geofence may be a geofence corresponding to the user's home, a geofence corresponding to the user's company, and so on. In the case that the smart watch and the mobile phone have established a bluetooth connection, the mobile phone determines whether the mobile phone enters a certain preset geofence (called a target geofence) according to the current position and the information of the preset geofences. If so, the mobile phone determines whether trusted devices exist in the target geofence according to the device information in the trust ring.

Optionally, the mobile phone may obtain historical bluetooth scan information, and determine whether a trusted device exists in the target geofence according to the historical bluetooth scan information. The historical Bluetooth scanning information characterizes information of the terminal equipment found by the Bluetooth equipment of the mobile phone in the target geofence in a historical time period. Optionally, the historical bluetooth scan information may include scan time and scan location when the mobile phone scans to find the terminal device, and scan the found device information of the terminal device. The device information of the terminal device found by the bluetooth device scanning may include, for example, a MAC address, a device name, and the like. The mobile phone can determine which terminal devices are found by scanning in the target geofence in a historical time period according to the historical Bluetooth scanning information, and then determine whether trusted devices exist in the target geofence according to the device information in the trust ring. Specifically, the mobile phone can compare the historical bluetooth scanning information with the device information in the trust ring to confirm whether the device scanned by the mobile phone in the historical time period comprises the device in the trust ring. If so, it is determined that there is a trusted device within the target geofence. In the implementation mode, the mobile phone can quickly determine whether trusted equipment exists in the target geofence based on the historical Bluetooth scanning information, and the power consumption of the mobile phone is saved.

Optionally, after determining that the mobile phone enters the target geofence, actively scanning to find surrounding devices, acquiring information of the surrounding devices, comparing the information of the surrounding devices with the device information in the trust ring, and determining whether the trusted device exists in the target geofence.

Optionally, the mobile phone may also obtain device information and location information of each device in the trust ring from the cloud server, so as to determine whether a trusted device exists in the target geofence. The embodiment of the application does not limit the specific method for determining whether the trusted device exists in the target geofence by the mobile phone.

A trusted device of a cell phone within a target geofence may be considered a device that the user is trusted to not affect the security of the user's information. In this embodiment, a trusted device is exemplified as a large screen device.

Fig. 7 is a schematic application scenario diagram of another example of a connection method of a wearable device according to an embodiment of the present application. As shown in fig. 7, a target geofence 101 is illustrated as a geofence corresponding to a user's home. The user carries the handset 102 and wears the smart watch 103, and the handset 102 has established a bluetooth connection with the smart watch 103. When the user comes home with the mobile phone 102, the mobile phone 102 determines to enter the target geofence 101, and determines that a trusted device, which is the large screen device 104, exists in the target geofence 101 according to the historical bluetooth scan information.

S102, the mobile phone sends notification information to the intelligent watch, wherein the notification information is used for indicating that trusted devices (large screen devices) exist around.

Alternatively, the notification information may carry device information of the trusted device. In the embodiment of the application, the notification information can carry the equipment information of the large-screen equipment. The device information of the large screen device includes, but is not limited to, the MAC address of the large screen device, etc.

In one possible implementation, the smart watch may subscribe to notification information in advance with the phone, such that when the phone determines itself to enter the target geofence and there is a trusted device within the target geofence, the phone sends the notification information to the smart watch.

S103, the smart watch responds to the notification information and sends discoverable broadcasting (namely, a first broadcast message) to the surrounding devices, wherein the discoverable broadcasting is used for the surrounding devices to discover the smart watch.

In one embodiment, after receiving the notification information, the smart watch may periodically send a discoverable broadcast to the surrounding devices, so that the surrounding devices can discover the smart watch at any time when they need to connect to the smart watch. For example, the smart watch may send a discoverable broadcast to surrounding devices every 5s, until the trusted device receives the discoverable broadcast.

In one embodiment, device information of the smart watch and bluetooth connected information (i.e., first information) may be carried in the discoverable broadcast. The device information of the smart watch may include, but is not limited to, a MAC address. The bluetooth connected information is used to characterize that the smart watch has currently established a bluetooth connection with the handset. Alternatively, the bluetooth connected information may be characterized by predefined fields.

It can be understood that, in the case that the device information of the smart watch is carried in the discoverable broadcast, the smart watch may send the discoverable broadcast to all surrounding devices in response to the notification information, or may send the discoverable broadcast to the large-screen device in a directional manner according to the device information of the large-screen device carried in the notification information, that is, the device information (such as the MAC address) of the large-screen device carried in the discoverable broadcast. The smart watch directionally transmits discoverable broadcast to the large-screen device, and after other devices receive the discoverable broadcast, the other devices determine that the MAC address carried in the broadcast message is inconsistent with the MAC address of the smart watch, so that the discoverable broadcast message is discarded and is not analyzed continuously, the interference of the smart watch to other surrounding devices can be reduced, the power consumption of the surrounding devices is saved, and the user experience is improved.

S104, the large-screen device receives discoverable broadcasting sent by the intelligent watch.

Optionally, the large screen device may automatically receive the discoverable broadcast sent by the smart watch based on a communication mechanism preset in the bluetooth protocol.

S105, responding to a scanning discovery instruction input by a user on the large screen device, and enabling the large screen device to scan and discover the intelligent watch to acquire and display device information of the intelligent watch.

The scan discovery instruction is used for instructing the large screen device to perform scan discovery. Optionally, after the user starts the large screen device, an APP (e.g., a sports APP) that needs to interact with the smart watch in the large screen device may be opened, and a scan discovery instruction is input through the APP, for example, by clicking an add device card in an interface for managing bluetooth connection devices in the sports APP.

Fig. 8 is a schematic diagram of an interface according to an embodiment of the present application. As shown in fig. 8 (a), the large screen device starts a motion APP and displays a device interface 403 of the APP. An add-on device card 404 is included in the device interface 403, and a user can select the add-on device card 404 through a remote controller to input a scan discovery instruction.

It will be appreciated that, although the discoverable broadcast sent by the smart watch to the large-screen device in step S103 may carry device information (such as a MAC address) of the smart watch, after the user inputs the scan discovery instruction, the large-screen device may further acquire more device information from the smart watch, for example, one or more of a device name, a device type, and the like of the smart watch, so as to display the information in the interface.

Specifically, in response to a scan discovery instruction input by a user, the large screen device initiates a scan request to the smart watch. After receiving the scanning request, the intelligent watch sends a scanning response packet to the large-screen device for response. The scan response packet includes device information of the smart watch. And after the large screen device receives the scanning response packet, displaying the device information of the intelligent watch in the interface. Illustratively, the large screen device scan discovers the interface of the smart watch may be as shown in interface 405 of fig. 8 (b).

It should be noted that, because the discoverable broadcast is sent to the surrounding devices after the smart watch receives the notification information, when the discoverable broadcast sent to the large-screen device by the smart watch carries the device information of the smart watch and the bluetooth connected information, if the large-screen device receives the discoverable broadcast, the large-screen device can confirm that the current application scenario is that the smart watch is connected with the mobile phone and the large screen is a trusted device according to the device information of the smart watch and the bluetooth connected information. In this scenario, the large-screen device scan discovery smart watch may also be automatically triggered to perform the scan discovery operation without being triggered by a scan discovery instruction of the user. After the intelligent watch is automatically scanned and found, the large screen device can display the device information of the intelligent watch in the interface in a popup window mode and inquire whether a user establishes connection with the intelligent watch.

In short, this step S105 may also be replaced by a large screen device scanning for finding the smart watch based on Bluetooth connected information in the discoverable broadcast in response to the discoverable broadcast, and acquiring and displaying device information of the smart watch. Alternatively, the device information of the smart watch may be displayed in the form of a popup window (also referred to as a second interface). Therefore, the user does not need to manually trigger scanning discovery, the user operation is simplified, and the user experience is improved.

For example, as shown in fig. 9, a second interface may be shown at 901 and smart watch device information may be displayed in a pop-up window 902.

And S106, responding to the connection instruction 1 input by the user, and establishing a physical link with the intelligent watch by the large-screen device according to the device information of the intelligent watch.

The connection instruction 1 is used for indicating the large-screen device to establish connection with the intelligent watch. Optionally, the large screen device may display the device information of the smart watch and simultaneously display a connection control for inputting a connection instruction, through which the user may input the connection instruction 1.

Illustratively, as shown in fig. 8 (b), the user may select a connection control 407 in the card 406 of the smart watch a in the interface 405 shown in fig. 8 (b) through the remote controller to input a connection instruction 1. Of course, the user may input the connection instruction 1 by means of voice input or the like, which is not limited in the embodiment of the present application.

After receiving the connection instruction 1, the large-screen equipment establishes a physical link with the mobile phone.

And S107, displaying a pairing confirmation interface by the large screen device.

Specifically, after the large-screen device establishes a physical link with the smart watch, a confirmation pairing interface is displayed in the screen, wherein the confirmation pairing interface comprises inquiry information for inquiring whether a user confirms pairing with the smart watch. The display form of the inquiry information in the confirmation pairing interface can be various, for example, a popup window, a capsule, a card or a floating window, and the embodiment of the application is not limited in any way.

The confirmation pairing interface of the large screen device may be, for example, an interface 408 shown in fig. 8 (c), for example. A pop-up window 409 is included in the interface 408. Included in the pop-up window 409 are a confirm control 410 and a cancel control 411.

S108, responding to the fact that the user inputs a pairing confirmation instruction 1 in a confirmation interface of the large-screen device, and the large-screen device sends a pairing request to the intelligent watch.

The confirmation pairing instruction 1 is used for indicating the large-screen device to initiate a pairing request to the intelligent watch. Illustratively, as shown in fig. 8 (c), the user may click on a confirmation control 410 in the pop-up window 409, for example, to input a confirmation pairing instruction 1. After the user inputs the confirm pairing instruction 1, the large screen device may display the first pairing interface 412, as shown in (d) of fig. 8.

In some embodiments, the large screen device may not display the pairing confirmation interface, and may not need to input a pairing confirmation instruction by the user, and may directly send a pairing request to the smart watch after establishing a physical link with the smart watch. That is, the above-described "response to the user inputting the confirmation pairing instruction 1 in the confirmation interface" in step S107 and step S108 may not be performed, but the "large screen device in step S108 is directly executed to send the pairing request to the smart watch after the completion of the execution of step S105. Therefore, the user operation is further simplified, and the user experience is improved.

And S109, responding to a pairing request of the large-screen device, and displaying a pairing request interface by the intelligent watch.

Specifically, the intelligent watch displays a pairing request interface according to a pairing request sent by the large-screen device. The pairing request interface includes inquiry information for inquiring whether the user accepts the pairing request of the large-screen device. The display form of the query information in the pairing request interface may be various, for example, a popup window, a capsule, a card, a floating window, etc., which is not limited in any way according to the embodiment of the present application. In one embodiment, the pairing request interface may be similar to interface 501 shown in fig. 5 (a), except that the schematic of the device connected to the smart watch in the pairing request interface may be a schematic of a large screen device, rather than a schematic of a cell phone in interface 501.

S110, responding to the pairing request interface input by the user of the intelligent watch to receive a pairing instruction 1, and automatically disconnecting the Bluetooth connection with the mobile phone by the intelligent watch.

Specifically, the smart watch can determine that the trusted device of the mobile phone exists around according to the notification information, and determine that the user agrees to establish connection with the trusted device (large screen device) according to the pairing receiving instruction 1 input by the user, so that the smart watch can automatically disconnect the Bluetooth connection with the mobile phone. Automatic disconnection refers to the smart watch autonomously disconnecting from the bluetooth of the handset without requiring the user to perform a disconnection operation (e.g., clicking a delete device, de-provisioning a peer-to-peer).

Optionally, the smart watch may break the physical link with the watch and unbind from the handset.

Alternatively, the smart watch may simply disconnect the physical link with the handset, without releasing the binding relationship with the handset. In the embodiment, the intelligent watch receives the notification information sent by the mobile phone, so that the current application scene can be determined as that the intelligent watch is connected with the mobile phone, and trusted equipment, namely large screen equipment exists in the current surrounding environment. In this scenario, if the smart watch receives the pairing acceptance instruction 1 that the user agrees to pair with the large-screen device, it can be confirmed that the security of the user information is not affected even if the smart watch does not release the binding relationship with the mobile phone. Therefore, the intelligent watch can only disconnect the physical link with the mobile phone, so that when the subsequent intelligent watch is reconnected with the mobile phone, the pairing stage is not required to be re-entered, and the user is not required to execute operations (such as pairing confirmation operations) related to the pairing stage, thereby saving the execution programs of the intelligent watch and the mobile phone, simplifying the user operation and improving the user experience.

It should be noted that, in some other embodiments, the "automatic disconnection of the smart watch from the bluetooth connection of the mobile phone" may also be performed at other times, for example, when a pairing request sent by the large screen device is received. The present application is not limited in any way.

S111, the intelligent watch is paired with the large-screen device and a profile channel is established.

The accept pairing instruction 1 is used for indicating that a pairing request of the large-screen device is accepted. Optionally, the pairing request interface may include an accept pairing control, for example 502 shown in fig. 5 (a), and the user may click on the accept pairing control 502 to input the accept pairing instruction 1. Of course, the user may input the pairing command 1 in other manners, for example, voice input, key selection, etc., which is not limited in any way in the embodiment of the present application.

In the process of pairing the smart watch and the large screen device and establishing the profile channel, the large screen device may display a second pairing interface 413, as shown in fig. 8 (e), and the smart watch may display a third pairing interface, which may be similar to the interface 503 shown in fig. 5 (b), except that the schematic diagram of the device connected to the smart watch in the third pairing interface may be a schematic diagram of the large screen device, rather than a schematic diagram of the mobile phone in the interface 503, which is not described in detail.

Optionally, in this embodiment, the profile channel established by the smart watch and the large-screen device may include an HFP channel, an A2DP channel, and an SPP channel. After the intelligent watch is paired with the large-screen device and the channels are established, the intelligent watch and the large-screen device are connected through Bluetooth. After the bluetooth connection is completed, the interface of the large screen device may be as shown in (f) of fig. 8.

It should be noted that, when the connection between the large-screen device and the smart watch is other connection, for example, wi-Fi connection, pairing is not required, and the above pairing process may not be performed.

In this embodiment, a schematic diagram of connection changes between the smart watch and the mobile phone, and the large screen device may be referred to fig. 10. As shown in fig. 10 (a), before the method provided in this embodiment is executed, the mobile phone establishes a bluetooth connection with the smart watch. Optionally, the bluetooth connection between the mobile phone and the smart watch may include an HFP channel, an A2DP channel, an SPP channel, and the like. Thereafter, the smart watch, the mobile phone and the large screen device perform the above steps S101 to S111, the smart watch disconnects the bluetooth connection with the mobile phone and establishes the bluetooth connection with the large screen device, as shown in (b) of fig. 10. Optionally, the bluetooth connection between the smart watch and the large screen device may also include an HFP channel, an A2DP channel, an SPP channel, and the like.

As described above, in general, when the wearable device has established a connection with one terminal device, the wearable device is in a paired state, and in consideration of the security of user information, no discoverable broadcast is sent to the surroundings any more, and only after the user disconnects the connection and releases the binding relationship between the connection, the wearable device is triggered to send the discoverable broadcast to the surroundings again. In this embodiment, when the mobile phone detects that the mobile phone enters the target geofence and the trusted large-screen device exists in the target geofence under the condition that the mobile phone and the smart watch are connected by bluetooth, the mobile phone sends notification information to the smart watch. That is, the mobile phone recognizes the trusted large-screen device and then notifies the smart watch, so that the smart watch can learn the current application scenario that the smart watch has established a connection with the mobile phone, and the trusted device of the mobile phone, namely the large-screen device, exists around the smart watch. Under the scene, the intelligent watch can automatically send discoverable broadcast to surrounding equipment without the related operations of disconnection and unbinding by a user under the condition that the intelligent watch does not release the binding relation with the mobile phone and reestablishes connection with the large screen equipment, so that the intelligent watch can be scanned and discovered by the large screen equipment, and further, bluetooth connection with higher security is established with the trusted large screen equipment. Therefore, related operations of disconnection and unbinding by a user are saved, and user experience is improved. Further, when the smart watch receives a pairing request of the large-screen device, the smart watch can determine that the large-screen device is a device trusted by the mobile phone according to the notification information, so that the smart watch can automatically disconnect the mobile phone and establish connection with the large-screen device without displaying an interface for inquiring a user or manually disconnecting the connection by the user. Therefore, the Bluetooth connection of the intelligent watch is switched to the large-screen device by the mobile phone, and the user is not required to execute related operations of disconnection and unbinding, so that the user operation is simplified, and the user experience is further improved.

As analyzed above, the large-screen device is a trusted device of the mobile phone, so that the smart watch simultaneously establishes Bluetooth connection with the mobile phone and the large-screen device, and the security of user information is not affected. Therefore, referring to fig. 11, in another embodiment, after receiving the pairing request sent by the large-screen device, the smart watch may also display the pairing request interface directly in response to the pairing request without disconnecting the connection with the large-screen device. That is, step S110 may not be performed, and step S111 may be performed directly after step S109 is performed. Thus, the intelligent watch establishes a second path of Bluetooth connection with the large screen device while maintaining Bluetooth connection with the mobile phone.

Alternatively, in this embodiment, the profile channel established between the smart watch and the large-screen device may include only the SPP channel. Step S111 is that in response to the user inputting the pairing acceptance instruction 1 in the pairing request interface, the smart watch is paired with the large-screen device and an SPP channel is established.

Specifically, as described above, the smart watch can learn that the current smart watch has established a connection with the mobile phone, and the large screen device can learn that the smart watch has established a connection with the mobile phone through the bluetooth connection information in the discoverable broadcast. In the case that the connection between the smart watch and the mobile phone is established, the bluetooth connection between the large screen device and the smart watch is generally only used for transmitting data, so that when the profile channel is established, the smart watch or the large screen device can initiate a request to the opposite terminal, authentication encryption is performed on the smart watch or the large screen device, and after the current application scene is determined, only the SPP channel is established. Therefore, the connection process between the large-screen device and the intelligent watch can be simplified, profile channels are saved, and power consumption and resources of the large-screen device and the intelligent watch are saved.

In this embodiment, a schematic diagram of connection changes between the smart watch and the mobile phone, and the large screen device may be seen in fig. 12. As shown in fig. 12 (a), before the method provided in this embodiment is performed, the mobile phone and the smart watch have established a bluetooth connection. Optionally, the bluetooth connection between the mobile phone and the smart watch may include an HFP channel, an A2DP channel, an SPP channel, and the like. Thereafter, the smart watch, the mobile phone, and the large screen device execute the method in the present embodiment, the smart watch maintains the bluetooth connection with the mobile phone, and establishes the bluetooth connection with the large screen device, as shown in fig. 12 (b). Alternatively, the bluetooth connection between the smart watch and the large screen device may include only the SPP channel.

In this embodiment, similar to the previous embodiment, in this embodiment, when a mobile phone connected to the smart watch enters a target geofence and a trusted device of the mobile phone exists in the paired state, the smart watch can send discoverable broadcast to the surrounding, so that the large screen device can discover the smart watch, and related operations of disconnection and unbinding are not required to be performed by a user, thereby simplifying user operations. Further, when the intelligent watch receives a pairing request of the large-screen device, the intelligent watch can determine that the large-screen device is a device trusted by the mobile phone according to the notification information, and the safety of user information cannot be affected, so that the intelligent watch is not disconnected with the mobile phone, and a second path of Bluetooth connection with the large-screen device is directly established, and therefore a user can interact with the mobile phone and the large-screen device simultaneously through the intelligent watch, and user experience is improved.

It should be noted that the embodiments shown in fig. 6 and fig. 11 are described by taking the example that the user operates on the large screen device side, discovers the smart watch, and establishes a bluetooth connection between the smart watch and the large screen device. In some other embodiments, the user may also operate on the smart watch side, establishing a bluetooth connection between the two. Specifically, referring to fig. 13, the above steps S105 to S111 may be replaced by the following steps:

S121, the intelligent watch displays equipment information of the large-screen equipment according to the notification information.

Specifically, as described above, the notification information may include device information of the large-screen device, and thus the smart watch may display an interface (also referred to as a first interface) including the large-screen device information according to the device information of the large-screen device. Optionally, a connection control (also referred to as a first control) for user input of a connection instruction may be included in the interface.

The form of the first interface and the first control may be similar to the form of the device information and the connection control of the intelligent device displayed in the large-screen device, and will not be described again.

S122, responding to the user input connection instruction 2, and establishing a physical link with the large-screen device by the intelligent watch according to the device information of the large-screen device.

The connection instruction 2 is used for indicating the smart watch to establish connection with the large-screen device. Alternatively, the user may enter connect instruction 2 by clicking a connect control in the interface shown in the wristwatch.

S123, the intelligent watch displays a pairing confirmation interface.

After the intelligent watch establishes a physical link with the large screen device, a pairing confirmation interface is displayed in the screen. The confirmation pairing confirmation interface of the smart watch can be similar to the confirmation pairing interface of the large-screen device, and is not repeated.

S124, responding to the fact that the user inputs a pairing confirmation instruction 2 in a confirmation interface of the intelligent watch, and automatically disconnecting the Bluetooth connection with the mobile phone.

The pairing confirmation instruction 2 is used for indicating the intelligent watch and the large-screen device to initiate a pairing request. After receiving the pairing confirmation instruction 2 of the user, the intelligent watch automatically disconnects Bluetooth with the mobile phone. Similar to step S110, in this embodiment, the smart watch may disconnect the physical link with the watch and release the binding relationship with the mobile phone, or may disconnect only the physical link with the mobile phone, but not release the binding relationship with the mobile phone. Specific advantageous effects and the like are not described herein.

S125, the intelligent watch sends a pairing request to the large-screen device.

And S126, responding to a pairing request sent by the intelligent watch, and displaying a pairing request interface by the large-screen device.

And S127, responding to the input of a pairing accepting instruction 2 by a user in a pairing request interface of the large-screen device, pairing the intelligent watch with the large-screen device and establishing a profile channel.

In the embodiment shown in fig. 6, before the smart watch is paired with the large-screen device, the bluetooth connection with the mobile phone may not be disconnected, i.e. the bluetooth connection is maintained.

In this embodiment, the process of establishing connection between the smart watch and the large-screen device is similar to the process of steps S106 to S111, except that in this embodiment, the user outputs a connection instruction and confirms a pairing instruction at the smart watch side, and inputs a pairing instruction at the large-screen device side. That is, the user triggers the bluetooth connection of the smart watch with the large screen device on the smart watch side.

It is noted that, in addition to the beneficial effects as described in fig. 6 and 11, in this embodiment, the smart watch receives notification information sent by the mobile phone, where the notification information may include device information of the large-screen device, so that the smart watch may directly display the device information without scanning to discover the large-screen device, without a user manually triggering the scanning discovery, which further simplifies user operation and improves user experience.

Scene II:

in this embodiment, in the case that the bluetooth connection is established between the smart watch and the mobile phone, the second path bluetooth connection between the smart watch and the large screen device may be implemented by a cloud pairing method. The following is a detailed description with reference to the accompanying drawings.

Fig. 14 is a flowchart of another method for connecting a wearable device according to an embodiment of the present application, as shown in fig. 14, where the method includes:

S201, when Bluetooth connection is established between the intelligent watch and the mobile phone, and the mobile phone logs in a first user account, the mobile phone uploads information such as device information and a pairing key of the intelligent watch to a server through the first user account.

The server may be a cloud server. It can be appreciated that the mobile phone can upload device information, connection information, and the like of the wearable device currently connected with the mobile phone to the cloud server under the condition of logging in the first user account. The connection information refers to information for establishing a short-range wireless communication connection between the wearable device and the other device, and when the short-range wireless communication connection is a bluetooth connection, the connection information may be a pairing key or the like.

The above-mentioned process of step S201 is also called that the mobile phone synchronizes the information cloud of the smart watch.

S202, under the condition that the large-screen device logs in the first user account, responding to operation of checking surrounding wireless communication devices in the large-screen device by a user, and acquiring device information, pairing keys and other information of the intelligent watch from a server by the large-screen device according to the first user account.

That is, the large-screen device and the mobile phone use the same user account number (first user account number), and if the user performs an operation of checking the surrounding wireless communication device while the large-screen device is in a login state (i.e., an online state), the large-screen device may acquire device information and a pairing key of the smart watch from the cloud server according to the first user account number. Alternatively, the operation of looking at the surrounding wireless communication device may be, for example, the user opening a bluetooth switch, or in case the bluetooth switch is open, the user opening a sports APP and looking at the device, etc.

S203, displaying the device information of the intelligent watch by the large-screen device.

The device information of the smart watch includes, but is not limited to, one or more of a device name, a device type, a MAC address, etc. of the smart watch.

Alternatively, the large screen device may display device information of the smart watch at a device interface (also referred to as a third interface) of the sports APP in response to a user opening the sports APP and viewing an operation of the device. A control (also referred to as a third control) for inputting a connect instruction may be included in the device interface. For example, the device interface may be as shown in 1501 in fig. 15, and the device information of the smart watch may be displayed in the device information card 1502. A connection control 1503 may be included in the device information card 1502 for a user to enter connection instructions.

S204, responding to the input of a connection instruction 3 by a user in the large-screen device, and establishing a physical link with the intelligent watch by the large-screen device according to the device information of the intelligent watch.

Specifically, the connection instruction 3 is used for indicating that the large-screen device is connected with the intelligent watch. The user can select a connection control 1503 in the interface 1501 in fig. 15 through the remote controller to input a connection instruction 3.

S205, the large screen device sends a pairing request to the intelligent watch.

S206, responding to the pairing request, and displaying a pairing request interface by the intelligent watch.

S207, responding to the pairing request interface input of the user on the intelligent watch to receive a pairing instruction 3, and pairing the large screen device with the intelligent watch according to the pairing key and establishing an SPP channel.

The processes of steps S204 to S207 are similar to those of steps S108 to S111, and will not be repeated. In step S207, the large-screen device already knows the pairing key of the smart watch, so that the large-screen device and the smart watch do not need to generate the pairing key based on the information such as the random number, the pin code, the MAC address and the like at the pairing interface, thereby simplifying the pairing process.

The above-mentioned processes of steps S202 to S207 are also called as the large screen device obtaining the information of the smart watch from the cloud, and pairing and connecting, and short for cloud pairing.

In this embodiment, a connection change schematic diagram of the smart watch, the mobile phone and the large screen device may be as shown in fig. 16. Referring to fig. 16 (a), before the method provided in this embodiment is performed, the mobile phone establishes a bluetooth connection with the smart watch. The bluetooth connection between the handset and the smart watch may include HFP channel, A2DP channel, SPP channel, etc. After that, the smart watch, the mobile phone and the large screen device perform the above steps S201 to S207, and the smart watch maintains the bluetooth connection with the mobile phone, and at the same time, the large screen device establishes the bluetooth connection with the smart watch by means of cloud pairing, as shown in (b) of fig. 16. The profile channel between the smart watch and the large screen device may include only the SPP channel.

In this embodiment, under the condition that the mobile phone establishes bluetooth connection with the smart watch, the large screen device obtains device information and a pairing key of the smart watch from the server, so as to realize connection with the smart watch. Because the large-screen equipment and the mobile phone are logged in the same user account, the large-screen equipment is user-trusted equipment, the intelligent watch can simultaneously establish two paths of Bluetooth connection with the mobile phone and the large-screen equipment, the safety of the mobile phone and the large-screen equipment cannot be influenced, the binding relation with the mobile phone does not need to be released, the user operation is simplified, the user can interact with the mobile phone and the large-screen equipment through the intelligent watch, and the user experience is improved. Moreover, the large-screen device acquires and displays the device information of the intelligent watch through the cloud server, and a user does not need to scan and find the device information of the intelligent watch through the large-screen device or the intelligent watch, so that the operation can be further simplified, and the user experience is improved. Moreover, the large-screen device can acquire the pairing key of the intelligent watch through the cloud service, and the pairing key does not need to be negotiated with the intelligent watch, so that the pairing process is simplified. In addition, the mobile phone synchronizes the information cloud of the intelligent watch under the condition that Bluetooth connection is established with the intelligent watch, so that when the large-screen device is matched with the intelligent watch cloud, the mobile phone and the intelligent watch are still in a Bluetooth connection state. In this case, the bluetooth connection between the smart watch and the large-screen device is generally only used for transmitting data, so when the profile channel is established, the large-screen device and the smart watch only establish the SPP channel, thus the connection process between the large-screen device and the smart watch can be simplified, the profile channel is saved, and the power consumption and resources of the large-screen device and the smart watch are saved.

Scene III:

the embodiment of the application also provides a method for connecting the wearable equipment, which can be applied to application scenes in which the terminal equipment is connected with a plurality of the wearable equipment. For example, a plurality of users wear a smart watch or a sports bracelet, respectively, and are connected with a large screen device through the smart watch or the sports bracelet to perform multi-person team fitness or games.

As shown in fig. 17, the large screen device is equipped with a sports APP, which may include team fitness games, such as multi-player race games. Multiple users (team members) can wear smart watches respectively, and the smart watches are connected with large-screen devices respectively. In the game process, the movement data of the team member are collected through the intelligent watch and uploaded to the large screen device based on the connection of the intelligent watch and the large screen device. The large screen device performs processing such as analysis and comparison on the motion data of each team member, and outputs a game interface, a game result and the like.

In this scenario, a process of establishing connection between the large-screen device and each smart watch will be described below.

Fig. 18 is a flowchart illustrating a connection method of a wearable device according to another embodiment of the present application. As shown in fig. 18, the method includes:

S301, in response to a user inputting a team forming instruction (also referred to as a first instruction) in the large screen device, the large screen device sends a team BLE broadcast (also referred to as a second broadcast message) to surrounding devices.

The team forming instruction is used for instructing the large screen device to establish connection with the plurality of wearable devices and form a team, namely, a game group or a body building group. Alternatively, the team command may carry the number of team members, i.e. the number of wearable devices in the group, etc.

Optionally, BLE broadcast is used to request multiple surrounding wearable devices to establish bluetooth connection with the large screen device and join the group. The BLE broadcast may carry one or more of device information, game information, scene information, number of players, etc. of the large screen device. The device information of the large-screen device may include one or more of a name of the large-screen device, a MAC address of the large-screen device, manufacturer information of the large-screen device, and the like, for example. The game information may include the name of the game being played, etc. The scene information is used for representing application scenes of connection between the plurality of wearable devices and the large-screen device, and the scene information can comprise team games, team fitness and the like.

Exemplary, fig. 19 is a schematic diagram of an interface for performing team fitness games through a large screen device according to an embodiment of the present application, where, as shown in fig. 19 (a), an option 1902 for a multi-player race game may be included in a sports interface 1901 of a sports APP. When the user selects the option 1902 of the multi-player racing game through the remote controller, the interface 1903 of the multi-player racing game is entered as shown in fig. 19 (b). A plurality of team game controls 1904 may be included in the interface, with the user selecting a corresponding team control 1904 based on the number of team members desired. Taking the example of a user selecting a 4-person team game, in response to the user's selection, the large screen device begins transmitting a team BLE broadcast to surrounding devices.

S302, after each smart watch (taking smart watch a, b, c, d as an example in fig. 18) receives the team BLE broadcast sent by the large-screen device, query information and prompt information are displayed according to the team BLE broadcast.

The inquiry information is used for inquiring whether the user agrees that the smart watch establishes connection with the large-screen device and joining in the team. After the prompt information is used for prompting the intelligent watch to be connected with the large screen device, data of the intelligent watch can be transmitted to the large screen device.

In a specific embodiment, after the smart watch receives the team BLE broadcast sent by the large screen device, the interface schematic may be as shown in fig. 20 (a). The interface includes inquiry information 2001 and prompt information 2002. Included in the inquiry information 2001 are an agreement control 2003 and a rejection control 2004.

And S303, responding to the fact that the user inputs a connection approval and team organization instruction in the interface of the intelligent watch, and sending a connection approval message and a team approval message to the large-screen device by the intelligent watch.

The consent connection message is used to characterize that the smart watch agrees to establish a connection with the large screen device. The consent team message characterizes that the smart watch agrees to connect and teams, i.e., agrees to join the group.

It will be appreciated that in this embodiment, the consent to connect message and the consent to team message are triggered by one instruction of the user—the consent to connect and team instruction. In other embodiments, the grant connect message and the grant team message may also be triggered by two instructions, respectively. In addition, the message of agreeing to connect and the message of agreeing to group can be two separate messages, send to the large-screen device separately, can also be two parts of content carried in the same message, send to the large-screen device through a message, the embodiment of the application does not limit this at all.

Illustratively, the user may enter the consent connection and team instruction by clicking on consent control 2003 in diagram (a) of fig. 20.

And S304, the large screen device responds to the connection agreement message and the team agreement message, and establishes physical links with each intelligent watch respectively.

S305, pairing the large screen device with each intelligent watch, establishing an SPP channel, and adding the intelligent watches into the group.

Specifically, after the physical link is established, the large-screen device sends a pairing request to the intelligent watch, and the large-screen device receives the pairing request and enters a pairing stage. After pairing is completed, the large-screen device and the intelligent watch establish an SPP channel, and accordingly Bluetooth connection is established between the large-screen device and the intelligent watch. After the bluetooth connection is completed, the interface of the smart watch may be as shown in (b) of fig. 20, and the interface of the large screen device may display information of team members, i.e., connected smart watches, as shown in (c) of fig. 19.

After the Bluetooth connection is established, the large-screen device adds the intelligent watch into the group.

S306, each intelligent watch collects motion data of the user.

Specifically, each intelligent watch can collect the motion data of the user in real time. Optionally, the user's athletic data may include, but is not limited to, one or more of the user's speed, number of steps, heart rate, blood oxygenation, blood pressure, etc.

S307, in response to the user inputting a game start instruction (also referred to as a second instruction) in the large screen device, the large screen device acquires motion data from the smart watch based on the SPP channel.

After a user inputs a game starting instruction, the large screen device can acquire motion data from the intelligent watch based on the established SPP channel, and then game or body-building content display is performed according to the motion data.

In this embodiment, the large screen device sends a team BLE broadcast to the surrounding devices, and the smart watch displays prompt information and inquiry information in response to the team BLE broadcast. The user inputs a command of agreeing to connect and forming a team in the interface of the intelligent watch, and the large screen equipment is characterized by being trusted by the user, namely, the large screen equipment is trusted by the user, so that the intelligent watch can directly establish Bluetooth connection with the large screen equipment, the large screen equipment can simultaneously establish Bluetooth connection with a plurality of intelligent watches, a plurality of intelligent watches can conveniently send data to the large screen equipment simultaneously, the use requirements of the user in the scenes of forming a team game and the like are met, and the user experience is improved. In addition, under the team game or body building scene, the intelligent watch and the large screen device only transmit data, so that a profile channel between the large screen device and the intelligent watch can only comprise an SPP channel, resources and power consumption of the intelligent watch and the large screen device can be saved, the risk of losing user information can be further reduced, and the safety of the user information is further improved. Meanwhile, through displaying prompt information and inquiry information in the interface of the intelligent watch, the user is informed of information such as use scenes, and therefore interaction with the user is increased, safety of the user information is improved, and user experience is improved.

In another embodiment, before the plurality of smart watches establish connection with the large screen device, if the smart watch has established a bluetooth connection with another terminal device (e.g., a mobile phone), the smart watch may maintain the bluetooth connection with the other terminal device and establish a second path bluetooth connection with the large screen device, and in this case, the smart watch may establish an SPP channel with only the large screen device. Thus, the user is convenient to interact with two devices of the mobile phone and the large screen device through the intelligent watch, user experience is improved, and the intelligent watch and the large screen device only establish the SPP channel so as to save resources and power consumption of the intelligent watch and the large screen device.

In this embodiment, the process of establishing bluetooth connection between a large-screen device and a plurality of wearable devices may be as shown in fig. 21. As seen in fig. 21 (a), the wearable device includes a smart watch a, a smart watch b, a smart watch c, and a smart watch d. Before the method provided in this embodiment is executed, the smart watch a has established a bluetooth connection with the handset. Optionally, the bluetooth connection between the mobile phone and the smart watch a may include an HFP channel, an A2DP channel, an SPP channel, and the like. Thereafter, each of the smart watch, the mobile phone, and the large screen device performs the above steps, and establishes bluetooth connection with the large screen device, respectively, wherein the smart watch a maintains bluetooth connection with the mobile phone, as shown in (b) of fig. 21. Alternatively, the bluetooth connection between each smart watch and the large screen device may include only the SPP channel.

In yet another embodiment, before the user inputs the team forming instruction in the large screen device, if the large screen device has established a bluetooth connection with a certain smart watch, the smart watch confirms that the smart watch has established a connection with the large screen device after receiving the BLE broadcast sent by the large screen device, and the smart watch maintains the connection and displays query information according to the BLE broadcast, so as to query whether the user agrees to form a team, i.e. whether the user agrees to join the group. After the user inputs the enqueue approval instruction, the smart watch sends a enqueue approval message to the large screen device. And after receiving the agreement to group message sent by the intelligent watch, the large screen device joins the intelligent watch into a group.

In the above embodiment, the short-range wireless communication connection is a bluetooth connection, and the profile channel of the classical bluetooth device is taken as an example for illustration, and the data transmission channel between the wearable device and the terminal device may be an SPP channel based on the classical bluetooth device. In some other embodiments, the bluetooth device of the wearable device may also be a BLE bluetooth device, or a dual mode bluetooth device, etc. In this case, a data transmission channel under its protocol (i.e., BLE data transmission channel) may also be established based on the BLE bluetooth device. Thus, for wearable devices (such as a sports bracelet) in which some bluetooth devices are BLE bluetooth devices or dual mode bluetooth devices, the method provided by the embodiment of the application is also applicable. Further, for the short-range wireless communication protocols of other communication protocols, the short-range wireless communication protocols also have respective data transmission channels, and when the transmission channels are established by using the method provided by the embodiment of the application, the transmission channels corresponding to the functions required under the protocol are established.

In addition, for the wearable device of the dual-mode Bluetooth device, when the connection is established between the wearable device and the large-screen device and between the wearable device and the mobile phone through the method provided by the embodiment of the application, the connection can be established between the wearable device and the mobile phone through the classical Bluetooth device, and the connection can be established between the wearable device and the large-screen device through the BLE Bluetooth device. Or the connection is established with the large screen device through the classical Bluetooth device, and the connection is established with the mobile phone through the BLE Bluetooth device, so that the flexibility of use is improved, and the applicability of the method is also improved.
