Abstract
A Bluetooth receiving method, a Bluetooth receiver, and a Bluetooth audio device are disclosed in the present invention. The Bluetooth receiving method includes: obtaining load data and a CRC result of the load data, and processing the load data based on signal quality of each of a plurality of data segments in one or more pre-stored load data having failed CRC results when the CRC result of the load data fails and a remaining retransmission time for the load data is no longer available. The signal quality is determined based on a signal angle difference before and after judgment for each of the plurality of data segments in each load data during demodulation. By using solutions provided in the present invention, damage caused by a data loss to a voice or audio can be concealed, and data reliability of limited retransmission of Bluetooth can be effectively improved, thereby improving Bluetooth communication performance.
