Abstract

The invention provides a communication method, device and system for a Bluetooth device. The Bluetooth device comprises a first terminal and a second terminal which establishes Bluetooth communication connection with the first terminal. The first terminal determines a valid idle channel. The first terminal switches to the valid idle channel. The first terminal sends frequency information of the valid idle channel to the second terminal through Bluetooth, so the second terminal can switch to the valid idle channel according to the frequency information of the valid idle channel. The first terminal transmits an audio modulation signal to the second terminal through the valid idle channel, so the second terminal receives and plays the audio modulation signal. According to the communication method, device and system for the Bluetooth device provided by the invention, the problem that when audio information with a high audio quality demand is transmitted between the Bluetooth devices, the audio quality playing effect is poor due to signal distortion resulting from limitation of a frequency response range is solved.

Description

technical field [0001] The invention relates to the technical field of bluetooth, in particular to a communication method, device and system of bluetooth equipment. Background technique [0002] With the development of society, Bluetooth communication technology is becoming more and more mature. The communication equipment using Bluetooth communication not only has low electromagnetic radiation, but also frees hands when talking and listening to music. It consumes less power and is easy to carry. However, the functions of existing Bluetooth communication devices are relatively simple; at the same time, audio information with high sound quality requirements is limited by the frequency response range when transmitted between Bluetooth devices, and the signal will be distorted, making the playback sound quality poor. Contents of the invention [0003] The main purpose of the present invention is to provide a communication method, device and system for Bluetooth devices, which...
