Communication method, device, apparatus and system of dual-wireless Bluetooth communication network

Abstract

The invention discloses a communication method, device, apparatus and system of a double-wireless Bluetooth communication network. The method comprises the steps of creating a first Bluetooth link with a Bluetooth sound source device, wherein in the first Bluetooth link, a Bluetooth playing master device serves as a network master device for controlling the communication process of a dual-wirelessBluetooth communication network, and the Bluetooth sound source device and a Bluetooth playing slave device serve as network slave devices of the dual-wireless Bluetooth communication network; sending an audio data request instruction to the Bluetooth sound source device through the first Bluetooth link, and based on the audio data request instruction, sending an audio data packet to a Bluetoothplaying master device and a Bluetooth playing slave device in the dual-wireless Bluetooth communication network by the Bluetooth sound source device; and keeping the state of not sending the audio data request instruction to the Bluetooth sound source equipment before the requirement of retransmitting the audio data packet exists. The problems of bandwidth waste and high power consumption caused by always sending data when the Bluetooth sound source device is used as a network main device are avoided.

Description

technical field [0001] The invention relates to the technical field of bluetooth communication, in particular to a communication method, device, equipment and system of a dual wireless bluetooth communication network. Background technique [0002] In the application of dual wireless Bluetooth communication, such as dual wireless Bluetooth headsets, dual wireless Bluetooth speakers and other scenarios, three Bluetooth devices need to communicate through at least two Bluetooth links, thus forming a dual wireless Bluetooth device communication system. That is, the dual wireless bluetooth device communication system includes three bluetooth devices, one of which is a bluetooth audio source device (such as a mobile phone, a notebook computer, etc.), etc.), the two playback devices are wireless Bluetooth devices, and the Bluetooth playback device connected to the Bluetooth audio source device is usually called the Bluetooth playback master device, and the Bluetooth playback device...

AI Technical Summary

Problems solved by technology

[0005] Bluetooth audio source device 101' and Bluetooth player master and slave devices (102', 103') are usually provided by different manufacturers. It will be difficult to evaluate whether the effect of dual Bluetooth communication is the best if the communication is carried out on the frequency point which is seriously interfered, which will affect the competitiveness of the product

However, because there is also a second bluetooth link between the bluetooth play master and the bluetooth play slave in the network slave, and the bluetooth sound source device 101' cannot learn the communication status of the second bluetooth link, therefore, as the network master It is difficult for the Bluetooth audio source device 101' of the device to evaluate performance problems such as dual Bluetooth communication quality and interference

[0006] In addition, in the existing network, the Bluetooth audio source device 101' will continuously resend audio data so that the Bluetooth playback master and slave devices (102', 103') can receive and monitor, thereby making the Bluetooth audio source device The power consumption of 101' increases; and, since the three are performing data transmission and reception operations at the same time, there will be signal interference between them
