Abstract

The invention relates to a Bluetooth communication method, a Bluetooth communication system, a Bluetooth receiving method and a Bluetooth receiving device. The Bluetooth communication method comprisesthe steps of: sending generated Bluetooth data through multiple Bluetooth sending branches in different frequency-domain channels; receiving the Bluetooth data in multiple Bluetooth receiving branches through different frequency-domain channels, wherein the Bluetooth data includes cyclic redundancy check information and load data; and, determining a current working mode, determining whether the load data in the multiple Bluetooth receiving branches is retransmitted or not in the current working mode according to the cyclic redundancy check information in the multiple Bluetooth receiving branches, and screening out output data in non-retransmission load data. According to the Bluetooth communication method, the Bluetooth communication system, the Bluetooth receiving method and the Bluetooth receiving device disclosed by the invention, the Bluetooth data is received/sent through the multiple different frequency-domain channels; furthermore, a check retransmission mechanism in differentworking modes is provided; therefore, the Bluetooth system retransmission time is effectively reduced, so that the communication efficiency is increased; and thus, high-quality and reliable Bluetoothinformation transmission is completed.

Description

technical field [0001] The present application relates to the technical field of Bluetooth communication, in particular to a Bluetooth communication method and system, and a Bluetooth receiving method and device. Background technique [0002] The extensive development of Bluetooth technology has made Bluetooth products and services a part of people's lives, especially voice or audio applications such as Bluetooth headsets and Bluetooth speakers have brought great convenience to people's lives. However, as people have higher and higher requirements for voice and audio performance, communication distance, real-time performance or communication reliability, the Bluetooth technology designed with low cost and low power consumption as the goal has more and more shortcomings in communication distance and reliability. more and more obvious. [0003] The Bluetooth wireless communication system mainly adopts frequency diversity technology based on adaptive frequency hopping and auto...
