Embodiment 1

[0041] figure 1 A schematic flowchart of an audio data transmission method according to an embodiment of the present invention is shown.

[0042] Such as figure 1 As shown, the audio data transmission method according to an embodiment of the present invention includes: step 102, when receiving the communication voice of the communication terminal through the first Bluetooth module and playing it through the hands-free playback device, through the second Bluetooth module. The audio to be played is sent to the peripheral Bluetooth audio device to be played by the peripheral Bluetooth audio device, wherein the Bluetooth protocol stack is encapsulated in the second Bluetooth module to identify the hardware abstraction of the connection between the second Bluetooth module and the peripheral Bluetooth audio device layer.

[0043] Such as Figure 7 As shown, in this embodiment, by encapsulating the Bluetooth protocol stack in the second Bluetooth module 704 itself, the second Blue...

Abstract

The invention provides an audio data transmission method, a vehicle machine platform, a vehicle machine and a readable storage medium. The audio data transmission method comprises the following steps:the communication voice of the communication terminal is received through one of the first Bluetooth module and the second Bluetooth module, and is played by a hand-free playing device; and the audioto be played is transmitted to the peripheral Bluetooth audio equipment through the other one of the first Bluetooth module and the second Bluetooth module, so that the audio to be played is played by the peripheral Bluetooth audio equipment. According to the technical scheme, the problem that in the prior art, a Bluetooth hardware abstraction layer and an audio hardware abstraction layer repel each other can be solved, and then audio receiving requirements of different users can be met on the same vehicle machine platform.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to an audio data transmission method, a vehicle-machine platform, a vehicle-machine and a computer-readable storage medium. Background technique [0002] In the related art, the user's mobile phone is connected via Bluetooth through a vehicle-machine HMI (Human Machine Interface, vehicle-machine user interface), or connected with the user's Bluetooth headset. [0003] Among them, when using the music player application on the car to play music, the main process includes: transmitting the music data stream to the Audio module, and the Audio module transmits it through the Audio A2DP (Advanced Audio Distribution Profile) HAL (Hardware Abstraction Layer) To the Bluetooth of the car, the Bluetooth of the car is transmitted to the Bluetooth headset through the ACL (Asynchronous Connectionless) link using A2DP, so as to realize the playback of music on the Bluetooth headset. ...
