step S10, controlling the first control device to establish an audio transmission channel with a terminal based on the general specification of a low-power consumption Bluetooth protocol stack;
here, the audio transmission channel is specifically a communication data transmission channel for transmitting audio data.
When receiving the first instruction, the first control device can be controlled to establish an audio transmission channel with the terminal according to a general specification (GATT protocol) of a bluetooth low energy protocol stack (BLE protocol stack). By the mode, compared with the mode that the data channel is established between the existing first control equipment and the terminal by adopting the A2DP protocol, the load of the first control device is lower, the energy consumption of the first control device is greatly reduced, and the cruising ability of the control equipment is ensured.

In order to avoid the energy consumption of large data transmission such as audio data, the first control device and the second control device are connected based on a file distribution protocol to form a control signal link, and the control signal link is only used for transmitting control signals, but not audio data. Specifically, the link for the Audio data related control signal may be formed based on an AVRCP protocol (Audio/Video Remote Control Profile, audio/video remote control specification) connection.

When the audio transmission channel is established, or when the first control device receives an instruction that the terminal needs to transmit audio data, the first control device can be controlled to generate a first message. The first message is sent to the second control device via a control signal link between the first control device and the second control device.
The first message is specifically an enabling message for driving the second control device to monitor the audio transmission channel.
When the second control device receives the first message of the first control device, the second control device can be controlled to start monitoring the transmission data in the audio transmission channel, and the transmission data in the audio transmission channel is copied to the second control device. Because the terminal sends the audio data to the first control device through the audio transmission channel, the second control device can receive the audio data sent to the first control device by the terminal through monitoring the audio transmission channel. It should be noted that, the process of sending the audio data to the first control device by the terminal is not affected by the listening of the second control device to the audio transmission channel.

In order to ensure that the second control device can rapidly realize monitoring of the audio transmission channel, the first message may specifically include configuration information of the audio transmission channel, based on which, the step S10 of controlling the first control device to send the first message to the second control device, so that the second control device monitors and receives data transmitted in the audio transmission channel includes: and controlling the first control device to send a first message to the second control device, so that the second control device monitors and receives the data transmitted in the audio transmission channel according to the configuration information. The configuration information specifically comprises connection parameters, connection keys and the like between the terminal and the first control device.
After the second control device receives the first message, configuration information in the first message can be extracted, and the second control device is controlled to acquire the monitoring authority of the audio transmission channel by adopting the configuration information, so that monitoring and receiving of data transmitted in the audio transmission channel are realized.
It should be noted that, the specific number of the first control devices connected to the terminal is one, and the second control device may be provided with one or more than one according to the need.
Further, based on the above embodiments, referring to fig. 3, another embodiment of the audio data processing method of the present application is provided. In this embodiment, after the step S20, the method further includes:
when the first control device receives the audio data, step S30 is executed: extracting part of data in the audio data as first data;
specifically, the first control device can be controlled to separate the received audio data to form data required to be played by the first control device and the second control device, and the partial data required to be played by the first control device is extracted as the first data.

Specifically, when the second control device has received the first frame of audio data, state information including a first state is generated; and when the second control device does not receive the first frame of audio data, generating state information comprising a second state. After the first control device receives the status information, the first data is played according to the received status information, and the specific implementation process can be referred to the above embodiment, which is not described herein.
In this embodiment, in the process that the second control device monitors the audio transmission channel, state information about the audio data receiving state is sent to the first control device, so that the playing of the first data in the first control device can be adapted to the data receiving state of the audio data in the second control device, which is beneficial to ensuring the synchronicity when the first control device and the second control device cooperate to play the audio data.
In addition, the embodiment of the invention also provides a readable storage medium, wherein the readable storage medium stores an audio data processing program, and the audio data processing program realizes the relevant steps of any embodiment of the audio data processing method when being executed by a processor.
