In this embodiment, the communication module may receive the server data through wireless communication, for example, bluetooth, wi-Fi, etc., or may receive the server data through wired communication, for example, twisted pair, coaxial cable, etc., which is not limited in the embodiment of the present application. The communication module caches the server data, and sends the server data after the host is confirmed to be awakened, so that the loss of the server data can be avoided, and the normal operation of the host service is ensured. In an exemplary embodiment, the communication module transmits server data in a low power mode, the transmission control module of the communication module receives the server data, and then notifies the power module that the server data has been received by transmitting EVENT (EVENT) information, and the power module wakes up the host after receiving the EVENT information.

The third signal is used for waking up the communication module. As an example, the host is an MCU chip, and the communication module may be awakened by transmitting the third signal to the communication module through the TX pin or by pulling the level of the wake_ready pin high, and the third signal may be a low pulse waveform or a high pulse waveform. As another example, the host is a DSP chip that can wake up the communication module by pulling the VBUS pin or the wake_ready pin high.

For example, the second signal sent by the HOST to the communication module is to pull high the host_ready pin level, so as to inform the communication module that the HOST has been awakened.

607. 608, The GPIO driver receives the interrupt and notifies the PM module that the host has been awakened.

The communication module triggers the interrupt after receiving the second signal, and in the embodiment of the application, the signal adopts NETLINK communication modes through the communication interface, NETLINK communication is a special mechanism for communication between the kernel space and the user space, is also an inter-process communication mode, can also adopt other communication modes, and is not limited by the application.

Optionally, the host sends a third signal to the communication module for waking up the communication module.

Referring to fig. 7, fig. 7 is a flow chart of a wake-up method according to another embodiment of the application. The description of the communication module and the host involved in the method is referred to above and will not be described in detail here.

As shown, the device 701 is a mobile terminal, and can access to a wireless lan, which may be a mobile phone, a smart watch, a tablet, or other devices. The devices 702 and 705 are base stations, which may be the same base station or different base stations, and the functions of the two base stations are the same. The devices 703 and 704 are servers, where 703 server is a management server, 704 server is a target server, and 703 server can manage 704 server. 706 is a communication module, 707 is a host, and the two are connected by a USB mode or a UART mode. 708 is a device, such as a sharing bicycle, that integrates a communication module and a host. If the mobile terminal 701 and the device 708 belong to the same cell, the base stations 702 and 705 are the same base station, and if the mobile terminal 701 and the device 708 do not belong to the same cell, the base station of the cell to which the mobile terminal 701 belongs is 702, and the base station of the cell to which the device 708 belongs is 705. All the devices can perform data transmission according to the arrow direction to realize service interaction, and a specific communication flow of the embodiment of the application will be exemplified below.

As one example, a user needs to unlock the sharing bicycle. The user uses a mobile terminal 701, such as a mobile phone, which is located in a cell where the base station 702 is located, and establishes a communication connection with the base station 702. When a user has a need to use the shared bicycle 708, and scans the two-dimensional code on the target shared bicycle 708 with the mobile phone 701, the mobile phone sends an unlocking request for unlocking the target shared bicycle 708 to the base station 702, and the unlocking request may include location information, device information and the like of the target shared bicycle 708. The base station 702 sends an unlocking request to the server 703, the server 703 is a management center, the server 703 determines a corresponding target server 704 according to the position information of the shared bicycle 708, the server 703 sends the unlocking request to the server 704, the server 704 is a data center, after receiving the unlocking request, information corresponding to the target shared bicycle 708 is found through analysis, and then the server 704 sends the unlocking information to the communication module 706 of the target shared bicycle 708 through the base station 705 where the target shared bicycle 708 is located. At this point, the communication module 706 and the host 707 in the sharing bicycle 708 are both in a low power consumption mode. After receiving the unlock request, the communication module 706 caches the unlock request information, then sends a wake-up signal to the host 707 through the RI pin for waking up the host 707, after the host 707 is woken up, sends a woken-up signal to the communication module 706 through the MCU READY pin, after confirming that the host 707 has been woken up, the communication module 706 sends an unlock request to the host 707, then the host 707 executes an unlock procedure, and finally the target sharing bicycle 708 is unlocked.

As another example, the sharing bicycle reports status and location information, and the user finishes paying the fee deduction and ends the use. The mobile terminal 701 establishes communication connection between the two by scanning the two-dimension code of the shared bicycle 708, after the user uses the shared bicycle 708, the shared bicycle 708 reports the current state and the position information, the base station 705 receives the state and the position information and forwards the information to the target server 704, the target server 704 calculates the riding time according to the information, then determines the riding cost according to the riding time, and reports the riding time and the charging result to the management server 703. The management server 703 determines the base station 702 of the cell where the user is located according to the user information, then sends the riding time and the charging result to the base station 702, the base station 702 feeds back the riding time and the charging result to the mobile terminal 701, the user finishes payment, and the riding of the shared bicycle is finished.

In the embodiment of the present application, the communication module 706 receives the data sent by the server 704 during the low power mode and caches the server data, and then the communication module wakes up the host 707, receives the wake-up signal sent by the host 707, and sends the cached server data when the host 707 is confirmed to be woken up, so that the risk of losing the server data can be reduced.
