Embodiment 1

[0041] Embodiment 1 of the present invention provides a Bluetooth-based audio transmission method, and describes the Bluetooth-based audio transmission method provided by the present invention from the side of the Bluetooth device receiving BLE broadcast data. The steps of the method can be as follows figure 1 shown, including:

[0042] Step 101, receiving BLE broadcast data.

[0043] In this step, the Bluetooth device can receive the BLE broadcast data sent by other Bluetooth devices, and the BLE broadcast data carries an audio transmission request.

[0044] Specifically, in this step, the Bluetooth device may receive BLE broadcast data sent by at least two other Bluetooth devices.

[0045] Step 102, performing audio data transmission.

[0046] In this step, the Bluetooth device can send audio data to other Bluetooth devices or receive audio data sent by other Bluetooth devices after establishing a connection with other Bluetooth devices according to the received audio tran...

Embodiment 2

[0068] Embodiment 2 of the present invention provides a Bluetooth-based audio transmission method, and describes the Bluetooth-based audio transmission method provided by the present invention from the side of the Bluetooth device that sends BLE broadcast data. The steps of the method can be as follows Figure 4 shown, including:

[0069] Step 201, sending BLE broadcast data.

[0070] In this step, the Bluetooth device can send BLE broadcast data to other Bluetooth devices, and the BLE broadcast data carries an audio transmission request.

[0071] Specifically, in this step, the Bluetooth device may send BLE broadcast data to at least two other Bluetooth devices.

[0072] Step 202, perform audio data transmission.

[0073] In this step, the Bluetooth device may receive audio data sent by other Bluetooth devices or send audio data to other Bluetooth devices after establishing a connection with other Bluetooth devices that have received BLE broadcast data.

[0074] Of course,...

Embodiment 3

[0078] Embodiment 3 of the present invention provides a Bluetooth-based audio transmission method. In this embodiment, it can be assumed that the Bluetooth device receiving BLE broadcast data is a Bluetooth speaker (which can be recorded as the main speaker in this embodiment), and sends BLE broadcast data. The Bluetooth device is a plurality of Bluetooth speakers (each Bluetooth speaker that sends BLE broadcast data can be recorded as a slave speaker in this embodiment), and the schematic diagram of the system function framework can be as follows Figure 5 shown. Figure 5 In the illustration, the number of slave speakers is three as an example, and in this embodiment, the number of slave speakers is at least one.

[0079] The following describes the audio transmission process between a slave speaker that sends BLE broadcast data and a master speaker that receives BLE broadcast data. Assuming that in this process, the audio transmission request carried in the BLE broadcast d...

Abstract

The invention relates to the technical field of Bluetooth, in particular to an audio transmission method and device based on Bluetooth, a medium and equipment. The embodiment of the invention providesa scheme. The invention discloses Bluetooth equipment needing audio transmission. According to the technical scheme, the audio transmission request can be sent through the BLE broadcast data, audio transmission can be achieved after connection is established between the Bluetooth devices according to the audio transmission request, pairing does not need to be conducted in the prior art, the audiotransmission process is simplified, operation complexity is reduced, waiting time in the audio transmission process is shortened, and consumed time is shortened.

Description

technical field [0001] The invention relates to the technical field of bluetooth, in particular to a bluetooth-based audio transmission method, device, medium and equipment. Background technique [0002] Bluetooth is a low-cost, high-capacity, short-range wireless communication specification that enables data exchange between fixed and mobile devices. On this basis, Bluetooth headsets, Bluetooth speakers and other products came into being. [0003] The existing Bluetooth-based audio transmission scheme is mainly based on the Advanced Audio Distribution Profile (A2DP, Advanced Audio Distribution Profile) protocol and the Audio / Video Remote Control Profile (AVRCP, Audio / Video Remote Control Profile) protocol. [0004] A2DP stipulates the protocol stack software and usage method for transmitting high-quality music file data using Bluetooth asynchronous transmission channel mode. Based on this protocol, high-quality music can be transmitted through Bluetooth. AVRCP is designed...
