Embodiment 1

[0032] Equipment master-slave role switching system for wireless communication, such as figure 2 Shown: including the master device, slave device and host device, taking the Bluetooth headset as an example, the master device receives the data packet of the host device, for example, the host device can be a mobile phone or a computer, the data packet is language information or call information, the master device includes the master Processing module, the master earphone is the master earphone of the Bluetooth earphone, the main processing module is the main processor in the master earphone, the slave device includes the slave processing module, the slave earphone is the slave earphone of the Bluetooth earphone, and the slave processing module is the slave earphone The slave processor, the power supply and the microphone in the master device and the slave device use the existing design, which will not be repeated here. The slave processing module establishes a monitoring link fo...

Embodiment 2

[0040] The difference from Embodiment 1 is that when the communication quality of the main earphone is poor, the earphone is always used as the main earphone to receive data packets, which may easily cause the overall communication quality of the Bluetooth earphone to decrease, or even interrupt the communication. Therefore, in the main processing module of the main earphone When it is detected that the communication quality is lower than that of the slave earphone, the communication quality is characterized by the strength of the received signal and the success rate of receiving packets. The master earphone sends a role swap request to the slave earphone through the monitoring link, and the role exchange request is obtained from the slave processing module of the earphone. After changing the request, reply a confirmation packet to the main earphone in the monitoring link, then the main processing module of the main earphone switches roles to establish a monitoring link, and the...

Abstract

The invention relates to the technical field of Bluetooth headset communication, in particular to a device master-slave role switching system and method for wireless communication, and the method comprises the steps: S100, building a monitoring link for the communication between a master device and a host device; s200, when role switching between the master device and the slave device is triggered, switching the master device to the slave device; any one of the master device and the slave device initiates a role exchange request through a monitoring link; the method comprises the steps that arole interchange request is received, a role interchange time point is appointed in the role interchange request, the other party replies a received request confirmation packet for receiving the roleinterchange request through a monitoring link, the system comprises a master device, a slave device and a host device, the master device comprises a master processing module, and the slave device comprises a slave processing module. According to the invention, the roles of the master device and the slave device are interchanged, so that the energy consumption of the two devices tends to be consistent, the service life of the devices is prolonged, and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of bluetooth earphone communication, in particular to a device master-slave role switching system and method for wireless communication. Background technique [0002] Bluetooth headsets are typical products that use Bluetooth wireless communication technology for applications. Bluetooth headsets can interact with voice or call data without connecting cables to host devices such as mobile phones or computers. Bluetooth headsets greatly facilitate users when using electronic devices. The use of information interaction in the equipment process. [0003] The dual wireless bluetooth headset includes a master headset and a slave headset, and the two headsets play music from the master device or make a call synchronously. At present, the communication implementation schemes between the two earphones of the dual wireless Bluetooth earphone include: the first one is that the host device only communicates wit...
