Problems solved by technology

When the Bluetooth master device forwards data, if there is strong interference, or the distance between the Bluetooth master and slave devices is relatively far or blocked, then the data forwarding is prone to errors, and the music received by the Bluetooth slave device is prone to lag
The robustness and reliability of this Bluetooth data forwarding method are poor

Abstract

The invention provides a bluetooth communication system including a smart wireless device, a bluetooth master device and at least one bluetooth slave device, the smart wireless device and the bluetooth master device establish an ACL link connection according to the bluetooth wireless protocol; the bluetooth master device includes a first bluetooth chip, a second A Bluetooth chip establishes a CSB link, and generates CSB broadcast data; performs channel coding on the generated CSB broadcast data, and transmits the coded data to the Bluetooth physical layer for sending; the Bluetooth slave device includes a second Bluetooth chip, a second Bluetooth The chip establishes a CSB link, and the Bluetooth physical layer of the second Bluetooth chip receives the encoded data sent by the Bluetooth physical layer of the first Bluetooth chip, and performs channel decoding on the received encoded data, and restores the CSB broadcast data after decoding. The invention improves the bluetooth protocol between the master device and the slave device. The subsystem formed by the master device and the slave device adopts channel coding and decoding for the data to be transmitted, thereby improving the reliability of the entire audio data transmission.

Description

technical field [0001] The invention relates to the technical field of bluetooth communication, in particular to a bluetooth communication system and a communication method. Background technique [0002] With people's pursuit of wireless life, audio equipment such as wireless earphones and wireless speakers have entered ordinary families. As the most popular wireless connection method, Bluetooth is used in wireless earphones and wireless speakers. Not only get rid of the shackles of wires between smart devices (such as smart phones, personal computers, laptops, etc.) It can also get rid of the shackles of wires and realize true wireless connection. In the existing wireless Bluetooth system, the Bluetooth master device forwards data (which can be music or voice, etc.) to the Bluetooth slave device. According to the Bluetooth wireless protocol, an asynchronous connectionless (Asynchronous Connectionless, ACL) link can be established, and a PBD (Profile Broadcast Data) link c...
