Abstract

The present invention provides a master-slave connection switching method of a Bluetooth headset, the method comprising: a) a host device is connected to a Bluetooth master device through a first link, and a Bluetooth master device is connected to a Bluetooth slave device through a second link; b) The Bluetooth master device stops receiving the data packets sent by the master device, and sends the link information of the first link to the Bluetooth slave device; c) When the Bluetooth slave device receives the link information of the first link, it replies with an ACK confirmation flag; d) The Bluetooth slave device connects with the host device by establishing a third link according to the received link information of the first link; e) When the Bluetooth slave device receives the data packet of the third link sent by the host device, the Bluetooth The slave device sends an acknowledgment flag of successful packet reception to the Bluetooth master device, and at the same time connects with the master device through a third link. The present invention seamlessly switches the master device and the slave device of the wireless earphone under the condition that the master device is not disconnected.

Description

technical field [0001] The invention relates to the technical field of bluetooth headset communication, in particular to methods for master-slave connection switching, call monitoring and microphone switching of the bluetooth headset. Background technique [0002] The dual wireless Bluetooth headset includes two Bluetooth devices, one of which is connected to the host device (such as a mobile phone, a personal computer, a laptop, etc.) Connect, usually the Bluetooth device as a Bluetooth slave device. [0003] 1) Existing wireless bluetooth earphones, when performing master-slave switching between the bluetooth master ear device and the bluetooth slave device (for example: the bluetooth master device leaves the cochlea), it needs to be disconnected from the host device before switching. When playing music, there will be no music for more than one second, which seriously affects the user experience. [0004] 2) When the host device establishes a call, it will establish a Sy...
