Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a communication processing method applied to a bluetooth shield according to an embodiment of the present invention is described below, where the communication processing method according to the embodiment of the present invention includes:
in the embodiment of the invention, the Bluetooth shield refers to equipment integrating a Bluetooth function and a U shield function. When the bluetooth shield is in the USB communication connection state, it indicates that the bluetooth shield has been inserted into an external communicable device (the external communicable device is a device supporting USB communication, such as a PC, a notebook, etc.) through a USB interface and establishes a USB communication connection, and at this time, the bluetooth shield performs communication using a USB communication channel.
The Bluetooth connection message is related to the Bluetooth communication connection established by the Bluetooth shield.
In an application scenario, the bluetooth connection message may be a bluetooth connection request message initiated by a peripheral device and requesting to establish a bluetooth communication connection with the bluetooth shield. Specifically, when the bluetooth shield starts the bluetooth function, the bluetooth shield broadcasts the bluetooth related information thereof, so that the devices located around the bluetooth shield can search 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 devices located around the bluetooth shield and carries a device identifier (e.g., a device serial number) of the bluetooth shield. Specifically, if a history of establishing a bluetooth communication connection with the bluetooth shield exists in a certain device, when the subsequent device starts a bluetooth function, the device broadcasts a bluetooth connection message carrying a device identifier of the bluetooth shield. In the embodiment of the present invention, after the bluetooth shield starts the bluetooth function, a message unrelated to the bluetooth communication connection established by the bluetooth shield (i.e., a message not carrying the device identifier of the bluetooth shield) may be filtered from messages broadcasted by devices located around the bluetooth shield, and a bluetooth connection message related to the bluetooth communication connection established by the bluetooth shield (i.e., a message carrying the device identifier of the bluetooth shield) may be obtained from the messages.
In step 101, an acquisition event of the bluetooth connection message is monitored so that the user can know the acquisition event in time when the bluetooth connection message is acquired.
102, when monitoring an acquisition event of the Bluetooth connection message, controlling the Bluetooth shield to establish Bluetooth communication connection with corresponding equipment based on the Bluetooth connection message;
in step 102, when an acquisition event of the bluetooth connection message is monitored in the USB communication connection state of the bluetooth shield, it indicates that the bluetooth shield has a requirement for establishing a bluetooth communication connection, and at this time, the bluetooth shield is controlled to establish a bluetooth communication connection with a corresponding device based on the bluetooth connection message. Wherein, the corresponding device is the sending device of the Bluetooth connection message. Specifically, the process of the bluetooth shield establishing the bluetooth communication connection with the corresponding device based on the bluetooth connection message may be implemented by referring to the prior art, and is not described herein again.
103, if the bluetooth shield successfully establishes the bluetooth communication connection with the corresponding equipment based on the bluetooth connection message, disconnecting the USB communication connection of the bluetooth shield, and controlling the bluetooth shield to enter a bluetooth communication connection state;
in step 103, when the bluetooth shield successfully establishes a bluetooth communication connection with a corresponding device based on the bluetooth connection message (which is equivalent to a successful bluetooth pairing), the USB communication connection of the bluetooth shield is disconnected, and the bluetooth shield is controlled to enter a bluetooth communication connection state. When the Bluetooth shield is in the Bluetooth communication connection state, the Bluetooth shield communicates by adopting a Bluetooth communication channel. It should be understood that, if the bluetooth shield is powered on and is not in the USB communication connection state, the bluetooth shield will enter the bluetooth communication connection state at this time if the bluetooth shield successfully establishes the bluetooth communication connection with the peripheral device.
Specifically, the disconnecting of the USB communication connection of the bluetooth shield may be a USB soft-unplugging process performed on the bluetooth shield. The above USB soft-pull processing can be implemented by referring to the prior art, and is not described herein again.
To better understand the communication processing method shown in fig. 1, a specific application scenario is described below. The bluetooth shield in this application scenario includes: the Bluetooth safety chip comprises a Bluetooth chip module (used for providing a Bluetooth communication function), a safety chip (mainly used for carrying out digital decryption and storing a digital certificate) and a USB interface, wherein the Bluetooth chip module and the safety chip can be connected through a serial port, the USB interface and the safety chip are electrically connected, and in an application scene, the safety chip and the USB interface can be integrated in the safety chip module. When the bluetooth shield is in a USB communication connection state, if the bluetooth chip module obtains a bluetooth connection message, the security chip is not notified once, and a bluetooth communication connection is established with a corresponding device based on the bluetooth connection message, and when the bluetooth communication connection is successfully established with the corresponding device based on the bluetooth connection message, an instruction (for example, a notification message) indicating that the bluetooth communication connection is successfully established is sent to the security chip, and the security chip performs a USB soft-unplugging process on the bluetooth shield under the instruction of the instruction, and switches the communication channel of the bluetooth shield to a bluetooth communication channel, so as to control the bluetooth shield to enter the bluetooth communication connection state.
In order to avoid that when the user is performing a transaction through the USB interface of the bluetooth shield, the USB communication connection of the bluetooth shield is disconnected to affect the transaction, optionally, step 103 may be specifically represented as: and if the Bluetooth shield successfully establishes Bluetooth communication connection with corresponding equipment based on the Bluetooth connection message and the Bluetooth shield does not process an APDU command through a USB interface currently, disconnecting the USB communication connection of the Bluetooth shield and controlling the Bluetooth shield to enter a Bluetooth communication connection state. Specifically, for the APDU command, reference may be made to the existing description, and details thereof are not repeated herein. Further, step 102 may be followed by: if the bluetooth shield successfully establishes bluetooth communication connection with the corresponding device based on the bluetooth connection message and the bluetooth shield is currently processing an APDU command through a USB interface, then: and disconnecting the Bluetooth communication connection, or after waiting for the Bluetooth shield to process the APDU command, disconnecting the USB communication connection of the Bluetooth shield and controlling the Bluetooth shield to enter a Bluetooth communication connection state. Optionally, the USB interface of the bluetooth shield is turned off when the bluetooth shield is in the bluetooth communication connection state. By this alternative, when the bluetooth shield is in the bluetooth communication connection state, even if the bluetooth shield is plugged into the USB interface of an external communicable device such as a PC or a notebook, the bluetooth communication connection state of the bluetooth shield is maintained and the USB connection request (the USB connection request is used to request the bluetooth shield to establish the USB communication connection) is not received, i.e. the USB communication connection between the bluetooth shield and the external communicable device is not established. Of course, when the bluetooth shield is plugged into the USB interface of an external communicable device such as a PC or a notebook, the bluetooth shield can obtain power supply from the external communicable device regardless of whether a USB communication connection is established. In addition, in a scenario where the bluetooth shield is configured with a rechargeable battery, the rechargeable battery may 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 connects to an external communicable device through the USB interface, the USB connection request of the external communicable device is responded, wherein the external communicable device is a device supporting USB communication. Explaining by a specific application scene, when the bluetooth shield is in a bluetooth communication connection state and is inserted into an external communicable device through a USB interface, if the bluetooth shield is disconnected from the bluetooth communication connection at this time, because the USB interface of the bluetooth shield is inserted into the external communicable device, the USB interface of the bluetooth shield can be enabled at this time, so that the bluetooth shield can establish the USB communication connection with the external communicable device, thereby realizing automatic switching from the bluetooth communication connection state to the USB communication connection state.
In order to save the power consumption of the bluetooth shield, the bluetooth shield may be controlled to enter a sleep state or be powered off when the bluetooth shield does not establish a bluetooth communication connection and the USB interface of the bluetooth shield is not connected to an external communicable device (i.e., the USB interface is not plugged into the external communicable device). Optionally, the communication method in the embodiment of the present invention may include:
and if the USB interface of the Bluetooth shield is not connected with the external communication equipment when the Bluetooth shield is disconnected from the Bluetooth communication connection, controlling the Bluetooth shield to enter a dormant state or controlling the Bluetooth shield to shut down. Specifically, when the bluetooth shield disconnects the bluetooth communication connection, it may be detected whether the USB interface of the bluetooth shield is connected to an external communicable device, and if it is detected that the USB interface of the bluetooth shield is not connected to the external communicable device, the bluetooth shield is controlled to enter a sleep state or to be powered off; and/or when the USB interface of the Bluetooth shield is pulled out of the external communication equipment, detecting whether the Bluetooth shield is in a Bluetooth communication connection state, and if the Bluetooth shield is not in the Bluetooth communication connection state, controlling the Bluetooth shield to enter a dormant state or power off.
Further, in the dormant state of the bluetooth shield, the bluetooth shield can be waken up when detecting that the USB interface of the bluetooth shield is connected to an external communicable device or when receiving a preset first key instruction. And/or, in the power-off state of the bluetooth shield, controlling the bluetooth shield to be powered on when detecting that the USB interface of the bluetooth shield is connected with an external communication device or when receiving a preset second key instruction.
It should be noted that the communication processing method in the embodiment of the present invention may be applied to a communication processing apparatus, and the communication processing apparatus may be a stand-alone device or may be integrated in the bluetooth shield, which is not limited herein.
As can be seen from the above, in the embodiment of the present invention, when the bluetooth shield is in the USB communication connection state, the bluetooth shield is controlled to establish the bluetooth communication connection with the corresponding device, and when the bluetooth communication connection is successfully established, the bluetooth shield is controlled to disconnect the USB communication connection of the bluetooth shield, and the bluetooth shield is controlled to enter the bluetooth communication connection state, so that the bluetooth shield is automatically switched from the USB communication connection to the bluetooth communication connection. The switching process does not need human participation, so that the operation process of switching the Bluetooth shield from the USB communication connection state to the Bluetooth communication connection state is effectively simplified. In addition, the USB communication connection of the Bluetooth shield is disconnected when the Bluetooth shield and the corresponding equipment successfully establish the Bluetooth communication connection, so that the effective switching of the communication connection state of the Bluetooth shield can be ensured.
