Problems solved by technology

[0003] When using a Bluetooth device to play audio, the mobile terminal transmits data to the Bluetooth device through the Bluetooth protocol. The Bluetooth protocol is a wireless transmission protocol. When it is affected by the interference of the surrounding environment and the Bluetooth device itself, data loss will occur, making audio playback Not smooth, not reliable

Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0032] When the audio data is transmitted to the Bluetooth device through the Bluetooth protocol for playback, because the Bluetooth protocol is a wireless protocol, it will be affected by the interference of the surrounding environment and the Bluetooth device itself, and data retransmission will occur, making the data in the Bluetooth protocol stack not timely. Send out and pile up. In the related technology, when the data backlog in the Bluetooth protocol stack is too much and there is not enough space to recei...

Abstract

The present invention discloses a Bluetooth audio data transmission method, a Bluetooth audio data transmission device, a terminal and a storage medium. The method includes the following steps that: first audio data are sent to a Bluetooth protocol stack, and the storage space state of the Bluetooth protocol stack is obtained; and if the storage space state of the Bluetooth protocol stack is not sufficient, the first audio data are not written into the Bluetooth protocol stack; and first audio data are retransmitted to the Bluetooth protocol stack. According to the Bluetooth audio data transmission method provided by the embodiments of the present invention, when the storage space state of the Bluetooth protocol stack is not sufficient, the first audio data are not written into the Bluetooth protocol stack; the first audio data are retransmitted to the Bluetooth protocol stack; and therefore, the loss of audio data can be avoided, audio playing streams are smooth, and the reliability of Bluetooth audio data transmission can be improved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of data transmission, and in particular to a transmission method, device, terminal and storage medium of Bluetooth audio data. Background technique [0002] With the rapid development of mobile communication technology and the popularity of smart terminal devices, mobile terminal devices have become an indispensable communication tool in people's lives. Since most mobile terminal devices support the Bluetooth function, some Bluetooth devices that match the terminal devices also emerge as the times require, such as Bluetooth headsets, Bluetooth speakers, and smart wearable devices. [0003] When using a Bluetooth device to play audio, the mobile terminal transmits data to the Bluetooth device through the Bluetooth protocol. The Bluetooth protocol is a wireless transmission protocol. When it is affected by the interference of the surrounding environment and the Bluetooth device itself...
