Problems solved by technology

When there is a lot of environmental interference at a certain moment, resulting in poor BLE CIS link quality, if a data packet has reached its corresponding number of retransmissions, the data packet will be discarded, correspondingly, the data in the data packet Frames are also dropped
Once data frames are frequently discarded, there will be a data interruption phenomenon on the earphone end, which will cause playback freezes

Abstract

The application provides a data transmission method, device, equipment, system and medium. The method includes: the transmitting end reduces the first encoding code rate of the transmitting end to thesecond encoding code rate; the transmitting end generates multiple first data frames according to the second encoding code rate and generates a plurality of first data packets, wherein each first packet includes a plurality of first data frames, and at least two packets in the plurality of first packets contain at least one same first data frame; and the transmission side generates a plurality offirst data frames according to the second encoding code rate The end sends multiple first packets to the receiving end. This eases the problem of playing carton

Description

technical field [0001] The present application relates to the technical field of Bluetooth communication, and in particular to a data transmission method, device, equipment, system and medium. Background technique [0002] At present, Bluetooth technology is mainly divided into classic Bluetooth and Bluetooth Low Energy (Bluetooth Low Energy, BLE). Compared with classic Bluetooth, Bluetooth Low Energy can effectively reduce power consumption. In the new version of the Bluetooth 6.0 standard, a new audio transmission technology based on Low Energy (LE) technology is proposed, which introduces an BLE is a point-to-point synchronous stream transmission connection (Connected isochronous stream, CIS) link, the BLE CIS link is specially used to transmit data to achieve low-latency and low-power Bluetooth transmission. This link is also called a BLE synchronous (Isochronous) link. [0003] When a BLE CIS link is established, the link will be configured with corresponding Quality ...
