Abstract

The application provides a method and a device for adjusting Bluetooth A2DP (Advanced Distribution Profile) coding setting. The method for adjusting Bluetooth A2DP coding setting provided by the invention, which is applied to a source, includes the following steps: when a Wi-Fi module state change event occurs in an initial state of an AVDTP (Audio / video Distribution Transport Protocol) link or after initialization of the AVDTP link, determining a coding setting matching the current state parameters of the Wi-Fi module of the source for the source; determining an enabling strategy of the coding setting according to the current state of the AVDTP link; and using the enabling strategy to enable the coding setting, and when the coding setting is enabled, sending the coding setting to a sink. The method and the device for adjusting Bluetooth A2DP coding setting provided by the application can ensure that the coding setting of the source can always adapt to Wi-Fi interference, in order to reduce the interference of Wi-Fi signals with transmitted data and to avoid sound quality problems caused by improper coding setting in the presence of Wi-Fi interference.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a method and a device for adjusting Bluetooth A2DP (Advanced Distribution Profile, A2DP for short) encoding settings. Background technique [0002] Bluetooth technology is a wireless communication technology working in the 2.4GHz frequency band. The emergence of Bluetooth technology enables users to listen to music through Bluetooth technology. The realization principle is: when the source device (Source, referred to as SRC, for example, it can be a smart TV) and the receiver device (Sink, referred to as SNK, for example, it can be a Bluetooth speaker) establish an AVDTP (Audio / videoDistribution Transport Protocol, referred to as AVDTP ) link, the source device encodes the audio data, and then sends the audio data to the receiver device through the AVDTP link established between the two devices, and the receiver device decodes and plays the audio data...
