The embodiment of the present application does not specifically limit the type of the wireless communication technology.

It should be understood that the embodiment of the present application is described by taking the Bluetooth connection as an example, but it may also be applicable to other wireless communication technologies.

The embodiment of the present application is described as an example in which the external device is a wireless earphone. The wireless earphone can be of various types, for example, it can be an earplug type, an in-ear type, a head-mounted type, an earmuff type or an ear-hanging type wireless earphone and the like.

FIG. 1 shows an example diagram of an application scenario of an embodiment of the present application. Taking the electronic device as a mobile phone and the external device as an earphone as an example, the earphone 11 is the device to which the mobile phone 10 was connected last time. After the Bluetooth function is turned on, the mobile phone 10 will automatically connect back to the earphone 11 connected last time. The headset 11 is currently no longer within the communication range of the mobile phone 10 (for example, the headset 11 is turned off or not near the mobile phone 10 ).

As shown in (1) in FIG. 1 , the Bluetooth management interface of the mobile phone 10 is displayed in the interface. When the bluetooth function of the mobile phone 10 is turned on, the "bluetooth can be found by nearby bluetooth devices" option is turned on. When this option is turned on, the mobile phone 10 can perform functions related to Bluetooth, such as searching, pairing, and connecting devices.

As shown in (1) in Figure 1, the interface includes a "Paired Devices" column. The “Paired Devices” column is used to display the devices that have been paired with the mobile phone 10 . "Paired Devices" shows that the earphone 11 is being connected.

In addition, during the automatic reconnection process of the earphone 11, the mobile phone 10 can also scan synchronously to find other available devices. For example, as shown in (1) in FIG. 1 , the scanned earphone 12 is displayed in the available device column. During the connection process of the earphone 11, if the user actively clicks to connect the earphone 12, the earphone 12 can only be connected after waiting for the automatic reconnection of the earphone 11 to time out. After waiting for a period of time, the connection to the headset 11 fails, and the interface of the mobile phone 10 is displayed as (2) in FIG. 1 .

As shown in (2) in FIG. 1 , if the automatic reconnection of the earphone 11 fails, a window 13 will pop up on the interface of the mobile phone 10 , and the window 13 is used to prompt the user that the connection of the earphone 11 fails.

It should also be understood that the scene in FIG. 1 is only a schematic illustration of an application scene of the present application, which does not limit the embodiment of the present application, and the present application is not limited thereto.

It should also be understood that the embodiment of the present application does not specifically limit the manner of how to enter the Bluetooth management interface. For example, the user can click the setting application, and then click the Bluetooth option in the setting application to enter the Bluetooth management interface, such as the Bluetooth management interface shown in (1) in Figure 1 .

Generally speaking, an external device (such as earphone 11 ) will try to connect twice. The connection timeout caused by these two connections will last for a few seconds (such as 16 seconds). During this period, if the user actively connects to another external device (such as the headset 12), the user needs to wait until the end of the connection process of the headset 11 before establishing another connection between the external device (such as the headset 12) and the electronic device (such as a mobile phone). 10), the connection speed of the earphone 12 will be very slow, which seriously affects the user experience.

In view of this, the embodiment of this application proposes a Bluetooth connection method. During the connection process of the second external device (such as the headset 11), if the electronic device detects the user's operation request to connect the first external device (such as the headset 12) , then canceling the connection of the second external device and establishing the connection between the electronic device and the first external device can speed up the connection of the first external device. For the situation that the second external device needs to wait for the connection timeout because it is not within the communication range, there is no need to wait for the aforementioned timeout period, which significantly improves the connection speed of the first external device and improves user experience.

Then the demodulator sends the demodulated low-frequency baseband signal to the baseband processor for processing. The low-frequency baseband signal is passed to the application processor after being processed by the baseband processor. The application processor outputs sound signals through audio equipment (not limited to speaker 370A, receiver 370B, etc.), or displays images or videos through display screen 394 . In some embodiments, the modem processor may be a stand-alone device. In some other embodiments, the modem processor may be independent from the processor 310, and be set in the same device as the mobile communication module 350 or other functional modules.

The wireless communication module 360 can provide WLAN (such as Wi-Fi), BT, global navigation satellite system (global navigation satellite system, GNSS), FM, NFC, IR or general 2.4G/5G wireless communication on the electronic device 300. Communication technology and other wireless communication solutions. The wireless communication module 360 may be one or more devices integrating at least one communication processing module. The wireless communication module 360 receives electromagnetic waves via the antenna 2 , frequency-modulates and filters the electromagnetic wave signals, and sends the processed signals to the processor 310 . The wireless communication module 360 can also receive the signal to be sent from the processor 310 , frequency-modulate it, amplify it, and convert it into electromagnetic waves through the antenna 2 for radiation.

In some embodiments, the wireless communication module 360 may be a Bluetooth chip. The electronic device 300 can pair and establish a wireless connection with the Bluetooth chip of electronic devices such as wireless earphones through the Bluetooth chip, so as to realize wireless communication and business processing between the electronic device 300 and other electronic devices through the wireless connection. This wireless connection can be a physical connection or a virtual connection. Bluetooth chips can usually support BR/EDR Bluetooth and BLE.

The electronic device 300 can realize the display function through the GPU, the display screen 194 and the application processor. The GPU is a microprocessor for image processing, and is connected to the display screen 194 and the application processor. GPUs are used to perform mathematical and geometric calculations for graphics rendering. Processor 310 may include one or more GPUs that execute program instructions to generate or alter display information.

Display 394 may be used to display images or video. Display 394 includes a display panel. The display panel can adopt liquid crystal display (liquid crystal display, LCD), organic light-emitting diode (organic light-emitting diode, OLED), active-matrix organic light-emitting diode (active-matrix organic light-emitting diode, AMOLED), flexible Light-emitting diode (flex light-emitting diode, FLED), mini light-emitting diode (mini light-emitting diode, Mini LED), micro light-emitting diode (micro light-emitting diode, Micro LED), micro OLED (Micro OLED) or quantum dots Diodes (quantum dotlight emitting diodes, QLEDs). In some embodiments, the electronic device 300 may include 1 or N display screens 394, where N is a positive integer greater than 1.

The electronic device 300 can realize the shooting function through the ISP, the camera 393 , the video codec, the GPU, the display screen 394 , and the application processor.

The ISP is used to process the data fed back by the camera 393 . For example, when taking a picture, open the shutter, the light is transmitted to the photosensitive element of the camera through the lens, and the light signal is converted into an electrical signal, and the photosensitive element of the camera transmits the electrical signal to the ISP for processing, and converts it into an image visible to the naked eye. ISP can optimize the algorithm of image noise, brightness and color, and ISP can also optimize parameters such as exposure and color temperature of the shooting scene. In some embodiments, the ISP may be located in the camera 393 .

Camera 393 is used to capture still images or video. The object generates an optical image through the lens and projects it to the photosensitive element. The photosensitive element may be a charge coupled device (charge coupled device, CCD) or a complementary metal-oxide-semiconductor (complementary metal-oxide-semiconductor, CMOS) phototransistor. The photosensitive element converts the light signal into an electrical signal, and then transmits the electrical signal to the ISP to convert it into a digital image signal. The ISP outputs the digital image signal to the DSP for processing. DSP converts digital image signals into standard red green blue (red green blue, RGB), YUV and other image signals. In some embodiments, the electronic device 300 may include 1 or N cameras 193 , where N is a positive integer greater than 1.

Digital signal processors are used to process digital signals. In addition to digital image signals, they can also process other digital signals. For example, when the electronic device 300 selects a frequency point, the digital signal processor is used to perform Fourier transform on the energy of the frequency point.

The electronic device 300 can implement audio functions, such as music playing and recording, through the audio module 370 , the speaker 370A, the receiver 370B, the microphone 370C, the earphone interface 370D and the application processor.

The audio module 370 is used to convert digital audio information into analog audio signal output, and can also be used to convert analog audio input into digital audio signal. The audio module 370 may also be used to encode and decode audio signals. In some embodiments, the audio module 370 or some functional modules of the audio module 370 may be set in the processor 310 .

Speaker 370A, also known as a horn, is used to convert audio electrical signals into sound signals. The electronic device 300 can listen to music or make a hands-free call through the speaker 370A.

Receiver 370B, also known as an earpiece, is used to convert audio electrical signals into audio signals. When the user uses the electronic device 300 to answer calls or voice messages, he can listen to the voice by placing the receiver 370B close to the ear.

Microphone 370C, also known as microphone or microphone, is used to convert sound signals into electrical signals. When the user makes a phone call or sends a voice message, a sound signal can be input into the microphone 370C by speaking close to the microphone 370C.

The earphone interface 370D is used to connect wired earphones. The earphone interface 370D may be a USB interface 330, or a 3.5mm open mobile terminal platform (OMTP) standard interface, or a cellular telecommunications industry association of the USA (CTIA) standard interface.

Keys 390 include a power key and a volume key. The button 390 may be a mechanical button or a touch button. The electronic device 300 can receive key input signals and implement functions related to case input signals.

The motor 391 can generate vibrations. The motor 391 can be used for incoming call notification, and can also be used for touch feedback. The motor 391 can generate different vibration feedback effects for touch operations on different application programs. For touch operations acting on different areas of the display screen 394, the motor 391 can also generate different vibration feedback effects. Different application scenarios (for example, time reminder, receiving information, alarm clock and games) can correspond to different vibration feedback effects. The touch vibration feedback effect can also support customization.

The connection relationship between the modules shown in FIG. 3 is only a schematic illustration, and does not constitute a limitation on the connection relationship between the modules of the electronic device 300 . Optionally, each module of the electronic device 300 may also adopt a combination of various connection modes in the foregoing embodiments.

The hardware system of the electronic device 300 is described in detail above, and the software system of the electronic device 300 is introduced below. The software system may adopt a layered architecture, an event-driven architecture, a micro-kernel architecture, a micro-service architecture, or a cloud architecture. The embodiment of the present application uses a layered architecture as an example to exemplarily describe the software system of the electronic device 300 .

FIG. 4 is a schematic diagram of a software system applicable to the electronic device of the present application. As shown in Figure 4, a software system adopting a layered architecture is divided into several layers, and each layer has a clear role and division of labor. Layers communicate through software interfaces. In some embodiments, the software system can be divided into four layers, which are application program layer, application program framework layer, local service native layer, hardware abstract layer (hardware abstract layer, HAL) and physical layer from top to bottom.

Wherein, the application program layer may include a series of application program packages. The Settings application and the Bluetooth application are shown in FIG. 4 . For example, the application layer may also include application programs such as camera, gallery, calendar, call, map, navigation, WLAN, music, video, and short message.

The application framework layer provides an application programming interface (application programming interface, API) and a programming framework for applications in the application layer. The application framework layer can include some predefined functions. As shown in Figure 4, the application framework layer includes the bluetooth service.

Optionally, the application framework layer may also include a window manager, a content provider, a view system, a phone manager, a resource manager, and a notification manager.

A window manager is used to manage window programs. The window manager can get the size of the display, determine whether there is a status bar, lock the screen, and capture the screen.

Content providers are used to store and retrieve data and make it accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, and phonebook.

The view system includes visual controls, such as those that display text and those that display pictures. The view system can be used to build applications. The display interface may be composed of one or more views, for example, a display interface including an SMS notification icon may include a view for displaying text and a view for displaying pictures.

The phone manager is used to provide communication functions of the electronic device 300, such as management of call status (connected or hung up).

The resource manager provides various resources to the application, such as localized strings, icons, pictures, layout files, and video files.

The notification manager enables the application to display notification information in the status bar, which can be used to convey notification-type messages, and can automatically disappear after a short stay without user interaction. For example, the notification manager is used for download completion notifications and message reminders. The notification manager can also manage notifications that appear in the status bar at the top of the system in the form of charts or scrolling text, such as notifications from applications running in the background. The notification manager can also manage notifications that appear on the screen in the form of dialog windows, such as prompting text messages in the status bar, making alert sounds, vibrating electronic devices, and blinking lights.

Android Runtime includes core library and virtual machine. The Android runtime is responsible for the scheduling and management of the Android system.

The core library consists of two parts: one part is the function function that the java language needs to call, and the other part is the core library of Android.

The application layer and the application framework layer run in virtual machines. The virtual machine executes the java files of the application program layer and the application program framework layer as binary files. The virtual machine is used to perform functions such as object life cycle management, stack management, thread management, security and exception management, and garbage collection.

The Native layer can improve some local services and link libraries, etc. Wherein, the Native layer may include a Bluetooth protocol stack. In some other embodiments, the Bluetooth connection method provided by the embodiment of the present application may also be realized by performing adaptive modification on the Bluetooth protocol stack in the Native layer. In some embodiments, the Bluetooth protocol stack may include a queue module. The queue module may include nodes (nodes) generated based on Bluetooth connection requests. For example, when the electronic device 300 automatically connects back to the second external device, nodes 1 and 2 are generated in the queue. Node 1 is used for processing the call connection request of the second external device, and node 2 is used for processing the media (such as music) connection request of the second external device. For example, the queue is sorted according to the order of node 1 and node 2.

In this embodiment of the application, if the electronic device receives a connection request from the first external device during the automatic connection back process of the second external device, the first external device is a priority connection device, and the connection request of the first external device passes through the node 3 processing, then in the queue, arrange node 3 ahead of node 1 and node 2, and process the request of node 3 preferentially, that is, preferentially connect to the first external device. For example, the queue is sorted in the order of node 3, node 1, and node 2. In addition, after the connection of the first external device is completed, the second external device may continue to be connected, that is, after the processing of node 3 is completed, the processing of nodes 1 and 2 continues.

It should be understood that the node 1, the node 2, and the node 3 are described here as examples, and this embodiment of the present application is not limited thereto. In fact, more nodes can be included in the queue as well.

The HAL layer is an interface layer between the operating system kernel and the hardware circuit, which can abstract the hardware. The physical layer provides the underlying hardware driver interface.

The kernel layer is the layer between hardware and software. The kernel layer may include driver modules such as display driver, camera driver, audio driver and sensor driver.

It can be understood that the electronic device 300 may also be another operating system, which is not limited in this embodiment of the present application. In some other operating systems, the framework layer and the Native layer can also be set as one layer. Therefore, in some other embodiments, the Bluetooth connection method provided by the embodiment of the present application may also be implemented by making adaptive modifications to the existing Bluetooth protocol in this layer.

It should be noted that, the foregoing is only to illustrate the structure of the electronic device by using FIG. 3 , and to illustrate the software architecture of the electronic device by using FIG. 4 , which is not specifically limited in this embodiment of the present application.

Take the bluetooth service Service in the framework layer as an example to illustrate. In the Bluetooth protocol based on the embodiment of the present application, the Bluetooth service Service in the framework layer of the electronic device determines that it has been paired with the Bluetooth headset, and when receiving the BLE broadcast message sent by the Bluetooth headset, it sends to the upper-level Bluetooth application (such as Bluetooth settings ( setting) application) to report that it has been connected to the Bluetooth headset. For example, the Bluetooth service Service in the framework layer can specifically notify the Bluetooth setting application that it has been connected to the Bluetooth headset through the Android broadcast message mechanism. The upper-level Bluetooth application displays related information about the connected Bluetooth headset, such as the battery level, on the relevant interface (for example, in the status bar of the display interface, or in the notification bar, or on the Bluetooth management interface, or on the negative 1 screen, etc.) , wearing status, business status, connection status, device name, device model, device icon, connection logo and other connected information. Wherein, the BLE broadcast message may include one of working status information such as device name, device type, device model, battery level, wearing status, connection status or business status of the Bluetooth headset. Wherein, the connection state information may indicate whether a physical connection has been established with the electronic device. The service status information may indicate whether the bluetooth headset is currently in an idle state, or the audio service being processed by the bluetooth headset. Moreover, the BLE broadcast message is sent periodically, and the Bluetooth application can update the relevant information of the connected Bluetooth headset displayed on the relevant interface in real time according to the status information of the Bluetooth headset in the BLE broadcast message obtained in real time.

The Bluetooth connection method in the embodiment of the present application will be described in detail below with reference to FIG. 5 to FIG. 9 . In the embodiment of the present application, the electronic device and the external device include a bluetooth module, and the electronic device and the external device are wirelessly connected through bluetooth as an example for description.

Referring to FIG. 5 , FIG. 5 shows an exemplary diagram of a method 500 for determining preferentially connected devices according to an embodiment of the present application. It can be understood that the method in FIG. 5 is applicable to electronic equipment. For example, it is applied to the scene shown in FIG. 1 . Method 500 in FIG. 5 includes the following steps:

In step 501, the electronic device turns on Bluetooth.

The embodiment of the present application does not specifically limit the entry for enabling the Bluetooth of the electronic device. For example, the user can slide down the notification bar (or status bar), and then click the Bluetooth control in the notification bar to enable the Bluetooth function. For another example, the user can enter the Bluetooth function switch option in the setting application program or the Bluetooth application program of the electronic device, and choose to enable the Bluetooth function.

In step 502, the electronic device performs automatic reconnection and starts scanning at the same time.

Exemplarily, after the Bluetooth function is turned on, the electronic device actively tries to connect to a recently connected device (or last connected device). In the embodiment of the present application, the recently connected device is named as the second external device. For example, the second external device is the earphone 11 shown in FIG. 1 .

While performing automatic reconnection, the electronic device can also start scanning synchronously to discover other connectable external devices. For example, the electronic device scans to the first external device. Scanning can also be understood as the process of searching or discovering new devices.

Step 503, the electronic device discovers the first external device.

For example, the first external device may be the earphone 12 shown in FIG. 1 .

The embodiment of the present application does not specifically limit the manner in which the electronic device discovers the first external device. The electronic device may discover the first external device through BR scanning, or may discover the first external device through BLE broadcasting.

Optionally, as an implementation, the electronic device discovers the first external device through BLE broadcasting, specifically as follows:

The first external device broadcasts an electronic device Bluetooth Low Energy BLE broadcast message, and the BLE broadcast message includes a Bluetooth address; correspondingly, after receiving the BLE broadcast message, the electronic device obtains the Bluetooth address by parsing the BLE broadcast message.

Optionally, the BLE broadcast message may be sent periodically by the first external device.

It should be understood that the foregoing BLE broadcast message may also include other information, which is not specifically limited in this embodiment of the present application.

Optionally, as an implementation manner, the electronic device discovers the first external device through BR scanning, including:

The electronic device sends an inquiry (inquiry) request to the first external device;

The first external device replies a response request message to the electronic device, and the response request message includes a basic rate BR address.

After receiving the response request information, the electronic device can know that the first external device has been scanned.

It should be understood that the two manners for discovering the first external device shown above are only exemplary descriptions, and this embodiment of the present application is not limited thereto. In fact, the electronic device may also discover the first external device in other reasonable ways.

After the first external device is scanned, the electronic device may perform a matching operation with the first external device based on the resolved Bluetooth address.

Exemplarily, after receiving the BLE broadcast message, the electronic device parses the BLE broadcast message to obtain the Bluetooth address, and performs pairing (or matching) with the first external device based on the Bluetooth address and the pairing list device.

Pairing refers to sharing a link key (link key) between the electronic device and the first external device. Link keys can be used to mutually authenticate Bluetooth devices and encrypt exchanged data. For example, the pairing manner of the Bluetooth device may include PIN code pairing (PIN code pairing) and secure simple pairing (secure simple pairing, SSP).

When the electronic device is successfully paired with the first external device, it can be considered that the first external device is in a paired state. At the same time, it can also be determined whether the first external device is connectable. The connectable state may be understood as a state in which the first external device is capable of being connected.

Step 504, judging whether the first external device is in a connectable and paired state.

Exemplarily, the paired state can be understood as: the state when the first external device can be searched by the electronic device, and the electronic device and the first external device are successfully paired.

In some possible implementation manners, the connectable state may be determined based on the maximum number of connected devices supported by the first external device. For example, the first external device supports connecting to two devices at most. If the first external device has already connected to one device, it means that the first external device can be connected again, and the first external device is in a connectable state.

If the first external device is in a connectable and paired state, step 504 is executed. If the first external device is not in a connectable state or a paired state, step 504 is not executed.

Optionally, after discovering the first external device, the electronic device may also display a first window (or a first pop-up window), so as to prompt the user that the first external device can be connected.

Optionally, the method 500 also includes:

A first interface is displayed, the first interface includes a first window, and the first window is used to prompt that the first external device can be connected.

Exemplarily, after the first external device is in a connectable and paired state, the user may also be prompted through the first window that the first external device is connectable. The first interface may be the interface shown in (1) in FIG. 8 later, and the first window may be the window 801 in (1) in FIG. 8 .

Optionally, the first window may further include an option or a control for connecting the first external device. After the user clicks the option of connecting to the first external device in the first window, the connection of the first external device may be initiated. An example of the first window will be described later in the interface in FIG. 8 .

Step 505, the electronic device sets the first external device as a priority connection device.

In the embodiment of the present application, the electronic device marks the first external device as a device for preferential connection. The device that is connected with priority means that the connection order is higher than that of the device that the electronic device is currently connecting to (such as the device that is automatically reconnecting).

It should be understood that the embodiment of the present application does not limit the specific marking manner of marking the devices for preferential connection.

Exemplarily, when the pairing of the first external device is successful, identification information may be added to the pairing information of the first external device, where the identification information is used to identify the first external device as a device that allows preferential connection.

Exemplarily, in the case that the first external device has not been paired, the first external device may be set as a priority connection device during the process of connecting the first external device based on the BLE result temporarily cached locally by the electronic device.

In the embodiment of the present application, the first external device is set as the priority connection device, which can facilitate the quick connection of the first external device for the user. The connection process of the first external device will be described below with reference to FIG. 6 .

Referring to FIG. 6 , FIG. 6 shows a schematic flowchart of a Bluetooth connection method 600 according to an embodiment of the present application. It can be understood that the method in FIG. 6 is applicable to electronic equipment. For example, it is applied to the scene shown in FIG. 1 . It should also be understood that the method in FIG. 6 may be implemented in combination with the method in FIG. 5 or may be implemented independently, which is not specifically limited. Exemplarily, when the method in FIG. 5 and the method in FIG. 6 are implemented in combination, the method in FIG. 5 may be executed first, and then the method in FIG. 6 may be executed.

As shown in FIG. 6, the method 600 includes the following steps:

In step 601, a first user operation is detected, and the first operation is used to instruct to initiate a Bluetooth connection of a first external device.

The first operation may be an operation initiated manually by the user to connect to the first external device. The embodiment of the present application does not limit the specific form of the first operation.

The first operation may be initiated at the electronic device or at the first external device, which is not specifically limited.

In one implementation manner, the user may click on the electronic device to connect to the first external device. For example, the description of step 504 in Figure 5 above mentioned that "when the user clicks the option to connect to the first external device in the first pop-up window, the connection to the first external device can be initiated", that is, the first operation can be the user clicking the first The option to connect the first external device in the pop-up window. For example, the first operation may be the operation of clicking the "Yes" option in window 801 in FIG. 8 .

In yet another implementation manner, the user may initiate a Bluetooth connection by touching the touch operation area of the first external device. This embodiment of the present application does not limit it.

The embodiment of the present application does not specifically limit the manner in which the electronic device discovers the first external device.

Step 602, determine whether the second external device is currently being connected.

Optionally, the second external device is an automatic connection back device of the electronic device.

The connection back refers to an operation in which the electronic device is trying to perform a connection back with a previously paired and connected second external device by means of paging. In some embodiments, the connection back includes: the electronic device sends a paging (page) data packet to the second external device to request establishment of a communication connection with the second external device.

Or, optionally, the second external device is a device that the user selects to connect to before initiating the first operation, and the second external device cannot currently establish a connection with the electronic device. Exemplarily, before detecting the first operation by the user, the electronic device further detects a second operation, and the second operation is used to indicate to connect the second external device.

Exemplarily, the second external device cannot establish a connection with the electronic device, including one or more of the following situations: the second external device is in a power-off state and cannot establish a connection with the electronic device; the second external device is far away from the electronic device, The data sent by the electronic device cannot be received because it is not within the communication range of the electronic device; the second external device has established a connection with other devices, and the maximum number of connections has been exceeded, so it cannot establish a connection with the electronic device.

It should be understood that the foregoing description about the situation that the second external device cannot establish a connection with the electronic device is only an exemplary description, and this embodiment of the present application is not limited thereto.

If the electronic device is being connected to the second external device, step 603 is executed to determine whether the first external device is a priority connection device. What is described here is that the first operation of the user is detected when the electronic device is being connected to the second external device. Certainly, if the electronic device is not being connected to the second external device, it is sufficient to directly initiate a connection with the first external device after detecting the user's first operation.

Step 603, in the case that the second external device is being connected, determine whether the first external device is a priority connection device.

The preferential connection device refers to a device (such as a second external device) that is connected in a higher order than the electronic device is currently connected to.

For the setting method of the preferentially connected device, reference may be made to the description of step 504 in FIG. 5 above. For the sake of brevity, details are not repeated here.

Exemplarily, when step 504 in FIG. 5 above is used to set the first external device as the priority external device, it can be judged here that the first external device is the priority connection device, that is, the connection of the first external device is better than that of the second external device. Connection of external devices.

Step 604, in response to the first operation, when it is determined that the first external device is the priority connection device, cancel the connection of the second external device, and establish a Bluetooth connection between the electronic device and the first external device.

Exemplarily, canceling the connection of the second external device may be understood as: for the second external device being connected, canceling or terminating the physical link connection of the second external device.

Optionally, after the connection between the first external device and the electronic device is completed, if it is necessary to restore the connection of the second external device, you may continue to try to connect the second external device.

In the embodiment of the present application, after the first operation of the user is detected, it is judged whether there is a second external device being connected; is the priority connection device; when the first external device is the priority connection device, canceling the connection with the second external device and establishing a Bluetooth connection with the first external device can significantly improve the connection speed and connection success of the first external device Rate. For the case where the second external device cannot be successfully connected, the embodiment of the present application can significantly increase the connection speed of the first external device on the premise of retaining the automatic connection back function.

Of course, if the first external device is not the priority connection device, you can add the connection request of the first external device to the queue, and connect in sequence according to the queue order. For example, after the connection of the second external device times out or ends, then connect to the first external device. equipment.

The following will be described in conjunction with the process in FIG. 7 as an example. It should be understood that for some features, terms, or concepts involved in FIG. 7 , reference may be made to the foregoing description, and details will not be repeated below. Taking the first external device as an example and the second external device as device B as an example, as shown in FIG. 7, the following steps are included:

In step 701, the user requests to connect to device A.

In step 702, the electronic device determines whether other devices (such as device B) are being connected.

If device B is connecting, execute step 703; if no other device is connecting, execute step 704.

In step 703, the electronic device determines whether device A is a priority connection device.

If device A is a preferentially connected device, step 705 is performed. If device A is not a preferentially connected device, step 707 is performed.

In step 704, the electronic device directly initiates a connection with device A.

Step 705, the electronic device cancels the connection of device B, and establishes the connection of device A.

For example, when it is determined that device A is the device to be connected with priority, the connection of device B is canceled and the connection of device A is initiated immediately.

Optionally, after step 705 is performed, step 706 may also be performed, that is, continue to connect to device B.

In step 707, the electronic device adds the connection request of device A to the queue, and executes the connection of device B.

Step 708, after the connection of the device B times out or ends, execute the connection of the device A.

It should be understood that the process in FIG. 7 is only an exemplary description, and this embodiment of the present application is not limited thereto. In fact, those skilled in the art can implement the above process with more steps or fewer steps on the basis of FIG. 7 .

Optionally, after establishing the Bluetooth connection between the electronic device and the first external device, the method 600 further includes:

A second interface is displayed, the second interface includes prompt information, and the prompt information is used to prompt that the first external device has been connected.

That is to say, after the first external device is successfully connected to the electronic device, the user can be prompted on the interface that the first external device has been successfully connected, so that the user can intuitively know that the first external device has been successfully connected.

It can be understood that other information may also be displayed on the second interface, which is not specifically limited in this embodiment of the present application.

The following description will be made in conjunction with the interface examples in FIG. 8 and FIG. 9 .

Referring to FIG. 8, FIG. 8 shows an example diagram of an interface according to an embodiment of the present application. As shown in (1) in FIG. 8 , the Bluetooth management interface of the mobile phone 10 is displayed in the interface. The interface shown in (1) in Figure 8 is similar to the interface shown in (1) in Figure 1 above, and the specific content of the interface will not be repeated here.

After adopting the Bluetooth connection method of the embodiment of the present application, as shown in (1) in Figure 8, when the earphone 11 is automatically reconnecting, if the earphone 12 is successfully paired with the mobile phone 10, a pop-up window can also be displayed on the interface of the mobile phone 10 801 (corresponding to the first window above). Window 801 includes options of "Yes" and "No". Window 801 is used to prompt the user to connect the headset 12 if the scan finds that the headset 12 is connected. If the user clicks the "Yes" option in window 801, the interface will display the interface as shown in (2) in FIG. 8 . Compared with FIG. 1 shown above, the earphone 12 in FIG. 8 does not need to wait for the connection with the earphone 11 to time out before establishing a connection with the mobile phone 10 . Therefore, the interface of (2) in FIG. 8 does not appear the connection failure window 13 shown in (2) in FIG. 1 .

It should be understood that the options included in the window 801, the position of the window 801 in the interface, and the size of the window 801 are only exemplary descriptions, and the embodiment of the present application is not limited thereto.

Exemplarily, the first operation of step 601 above may be that the user clicks the “Yes” option in window 801 .
