In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the application.

In order to explain the technical solutions described in the present application, the following description will be made by way of specific embodiments.

A communication processing method applied to the Bluetooth shield provided by the embodiment of the present application is described. Referring to FIG. 1, the communication processing method in the embodiment of the present application includes:

Step 101: Listening to an acquisition event of a Bluetooth connection message when the Bluetooth shield is in a USB communication connection state;

In the embodiment of the present application, the Bluetooth shield refers to a device that integrates the Bluetooth function and the U shield function. When the Bluetooth shield is in the USB communication connection state, it indicates that the Bluetooth shield has been inserted into the external communicable device through the USB interface (the external communicable device refers to a device supporting USB communication, such as a PC, a notebook, etc.) and establishes a USB communication connection. At this time, the Bluetooth shield uses the USB communication channel for communication.

The above Bluetooth connection message is related to establishing a Bluetooth communication connection with the Bluetooth shield.

In an application scenario, the Bluetooth connection message may be initiated by a peripheral device and used to request a Bluetooth connection request message for establishing a Bluetooth communication connection with the Bluetooth shield. Specifically, when the Bluetooth shield turns on the Bluetooth function, the Bluetooth shield broadcasts its Bluetooth related information, so that the device located around the Bluetooth shield can search for the Bluetooth shield based on the Bluetooth technology and initiate the Bluetooth connection request message for the Bluetooth shield.

In another application scenario, the Bluetooth connection message may also be a message that is broadcasted by a device located around the Bluetooth shield and carries the device identifier (eg, device serial number) of the Bluetooth shield. Specifically, if a history record of establishing a Bluetooth communication connection with the Bluetooth shield is present in a device, when the device starts the Bluetooth function, the device broadcasts a Bluetooth connection message carrying the device identifier of the Bluetooth shield. In the embodiment of the present application, after the Bluetooth function is enabled, the message that is not related to establishing a Bluetooth communication connection with the Bluetooth shield may be filtered from a message broadcasted by a device located in the periphery of the Bluetooth shield (ie, the Bluetooth shield is not carried. The message of the device identification) obtains a Bluetooth connection message (ie, a message carrying the device identifier of the Bluetooth shield mentioned above) associated with establishing the Bluetooth communication connection with the Bluetooth shield.

In step 101, the acquisition event of the Bluetooth connection message is monitored to be known in time when the Bluetooth connection message is obtained.

Step 102: When listening to the acquisition event of the Bluetooth connection message, controlling the Bluetooth shield to establish a Bluetooth communication connection with the corresponding device based on the Bluetooth connection message;

In step 102, when the acquisition event of the Bluetooth connection message is monitored in the USB communication connection state of the Bluetooth shield, it indicates that the current Bluetooth shield has a requirement for establishing a Bluetooth communication connection, and the Bluetooth shield is controlled based on the Bluetooth connection message. Establish a Bluetooth communication connection with the corresponding device. The foregoing device is a sending device of the foregoing Bluetooth connection message. Specifically, the process of establishing a Bluetooth communication connection between the Bluetooth Shield and the corresponding device based on the foregoing Bluetooth connection message may be implemented by referring to the prior art, and details are not described herein again.

Step 103: If the Bluetooth shield successfully establishes a Bluetooth communication connection with the corresponding device based on the Bluetooth connection message, disconnect the USB communication connection of the Bluetooth shield, and control the Bluetooth shield to enter a Bluetooth communication connection state;

In step 103, when the Bluetooth shield successfully establishes a Bluetooth communication connection with the corresponding device based on the Bluetooth connection message (equivalent to Bluetooth pairing success), the USB communication connection of the Bluetooth shield is disconnected, and the Bluetooth shield is controlled to enter the Bluetooth communication. Connection Status. Wherein, when the Bluetooth shield is in the Bluetooth communication connection state, the Bluetooth shield uses a Bluetooth communication channel for communication. It should be understood that if the Bluetooth shield is powered on and is not in the USB communication connection state, the Bluetooth communication connection is successfully established with the surrounding device, and the Bluetooth shield will also enter the Bluetooth communication connection state.

Specifically, the USB communication connection for disconnecting the Bluetooth shield may be a USB soft extraction process for the Bluetooth shield. The above USB soft extraction processing can be implemented by referring to the prior art, and details are not described herein again.

In order to better understand the communication processing method shown in FIG. 1, the following describes a specific application scenario. The Bluetooth shield in this application scenario includes: a Bluetooth chip module (for providing Bluetooth communication function), a security chip (mainly used for digital decryption and storing digital certificates), and a USB interface, wherein a Bluetooth chip module and a security chip are available Through the serial port connection, the USB interface and the security chip are electrically connected. In an application scenario, the security chip and the USB interface can be integrated in the security chip module. When the Bluetooth shield is in the USB communication connection state, if the Bluetooth chip module obtains the Bluetooth connection message, the security chip is not notified yet, and the Bluetooth communication connection is established with the corresponding device based on the Bluetooth connection message, when the Bluetooth connection message is based on the Bluetooth connection message. When the Bluetooth communication connection is successfully established with the corresponding device, an instruction (such as a notification message) indicating that the Bluetooth communication connection is successfully established is sent to the security chip, and the security chip performs USB soft extraction processing on the Bluetooth shield under the instruction of the instruction, and The communication channel of the above Bluetooth shield is switched to a Bluetooth communication channel to control the Bluetooth shield to enter the Bluetooth communication connection state.

In order to prevent the user from performing a transaction through the USB interface of the Bluetooth shield, since the USB communication connection of the Bluetooth shield is disconnected to affect the transaction, optionally, step 103 may be specifically performed as follows: if the Bluetooth shield is based on the Bluetooth connection. The message successfully establishes a Bluetooth communication connection with the corresponding device, and the Bluetooth shield does not currently process the APDU command through the USB interface, then disconnects the USB communication connection of the Bluetooth shield, and controls the Bluetooth shield to enter the Bluetooth communication connection state. The above APDU (the full name of the APDU in English) The Protocol Data Unit command is a command that is transmitted between the Bluetooth shield and the external communication device. Specifically, the APDU command can be referred to the existing description, and is not described here. Further, after the step 102, the method further includes: if the Bluetooth shield successfully establishes a Bluetooth communication connection with the corresponding device based on the Bluetooth connection message, and the Bluetooth shield is currently processing the APDU command through the USB interface, then: disconnecting the Bluetooth communication connection, or After waiting for the above-mentioned APDU command to be processed by the above-mentioned Bluetooth shield, the USB communication connection of the Bluetooth shield is disconnected and the Bluetooth shield is controlled to enter the Bluetooth communication connection state.

In addition, in the scenario where the Bluetooth shield is configured with a rechargeable battery, the rechargeable battery can be in a charging state at this time.

Further, when the Bluetooth shield disconnects the Bluetooth communication connection, the USB interface of the Bluetooth shield is enabled, so that when the Bluetooth shield is connected to the external communicable device through the USB interface, the USB connection request of the external communicable device is responded to, The above external communicable device refers to a device that supports USB communication. According to a specific application scenario, when the Bluetooth shield is in the Bluetooth communication connection state and has been inserted into the external communicable device through the USB interface, if the Bluetooth shield disconnects the Bluetooth communication connection at this time, the USB interface of the Bluetooth shield is The external communicable device has been inserted, and the USB interface of the Bluetooth shield can be enabled at this time, so that the Bluetooth shield can establish a USB communication connection with the external communicable device, thereby automatically switching from the Bluetooth communication connection state to the USB communication connection state.

In order to save the power consumption of the above-mentioned Bluetooth shield, the Bluetooth communication can be controlled when the Bluetooth communication connection is not established and the USB interface of the Bluetooth shield is not connected to the external communication device (ie, the USB interface is not inserted into the external communication device). The shield goes to sleep or shuts down. Optionally, the communication method in the embodiment of the present application may include:

If the USB interface of the Bluetooth shield is not connected to the external communicable device when the Bluetooth shield is disconnected from the Bluetooth communication, the Bluetooth shield is controlled to enter a sleep state or the Bluetooth shield is controlled to be shut down. Specifically, when the Bluetooth shield disconnects the Bluetooth communication connection, it is detected whether the USB interface of the Bluetooth shield is connected to the external communication device, and if the USB interface of the Bluetooth shield is detected to be not connected with the external communication device, then the control is performed. The Bluetooth shield enters a sleep state or is turned off; and/or, when the USB interface of the Bluetooth shield is pulled out from the external communicable device, detecting whether the Bluetooth shield is in a Bluetooth communication connection state, and if the Bluetooth shield is detected not to be in Bluetooth communication In the connection state, the above-mentioned Bluetooth shield is controlled to enter a sleep state or shut down.

Further, in the sleep state of the Bluetooth shield, the Bluetooth shield of the Bluetooth shield may be connected to the external communicable device or the preset first button command may be used to wake up the Bluetooth shield. And/or, in the shutdown state of the Bluetooth shield, the Bluetooth shield can be controlled to be connected when the USB interface of the Bluetooth shield is detected to be connected with the external communicable device or when a preset second button command is received.

It should be noted that the communication processing method in the embodiment of the present application may be applied to the communication processing device, and the communication processing device may be an independent device, or may be integrated into the Bluetooth shield, which is not limited herein.
