Problems solved by technology

When the smart device sends a Bluetooth audio data frame to the Bluetooth device, the Bluetooth device cannot receive it correctly due to communication conditions, which causes the smart device to resend it multiple times until the Bluetooth audio data frame is correctly received by the Bluetooth device.
Bluetooth devices usually use hard judgment to demodulate the received retransmitted Bluetooth audio data frame each time, and hard judgment often misses part of the data information in the Bluetooth audio data frame, thereby reducing the accuracy of data judgment nature, resulting in an increase in the number of retransmissions of Bluetooth audio data frames in the air, resulting in unnecessary waste of communication resources

Abstract

The invention relates to a Bluetooth communication method and a Bluetooth communication device. The Bluetooth communication method comprises the following steps: receiving a first Bluetooth frame sentfor the first time; determining first soft decision data based on the first Bluetooth frame; performing de-whitening processing on the first soft decision data to obtain de-whitened first soft decision data; receiving a retransmitted second Bluetooth frame, wherein the second Bluetooth frame and the first Bluetooth frame correspond to the same audio data but have different bit data due to whitening processing; determining second soft decision data based on the second Bluetooth frame; performing de-whitening processing on the second soft decision data to obtain de-whitened second soft decisiondata; and fusing the first soft decision data after de-whitening processing and the second soft decision data after de-whitening processing to obtain third soft decision data after de-whitening processing. Thus, when a Bluetooth device receives the Bluetooth frame retransmitted by an intelligent device for multiple times, the method can reserve more data information in the Bluetooth frame bit data and improve the accuracy of subsequent data judgment, thereby reducing the number of retransmissions of the Bluetooth frame in the air and improving the reliability of the system.

Description

technical field [0001] The present disclosure relates to the field of Bluetooth communication, and more particularly, to a Bluetooth communication method and a Bluetooth communication device. Background technique [0002] Smart devices (such as smartphones, laptops, tablets, etc.) realize the transmission and playback of audio data by establishing a communication connection with Bluetooth devices (such as Bluetooth headsets, Bluetooth speakers, etc.). When the smart device sends the Bluetooth audio data frame to the Bluetooth device, due to communication conditions, the Bluetooth device cannot receive it correctly, causing the smart device to resend it multiple times until the Bluetooth audio data frame is correctly received by the Bluetooth device. Bluetooth devices usually use hard judgment to demodulate the received retransmitted Bluetooth audio data frame each time, and hard judgment often misses part of the data information in the Bluetooth audio data frame, thereby red...
