TWS device connection method and medium

Abstract

The embodiment of the invention discloses a TWS device connection method and a medium.The method is used for a first TWS device of a TWS system, the TWS system comprises an intelligent device, the first TWS device and a second TWS device. The method comprises the following steps: S100, communicating with the intelligent device based on a standard Bluetooth protocol, and executing a step S200 after a first time interval; s200, searching the second TWS equipment based on a private protocol, after a second time interval, if the search is unsuccessful, returning to the step S100, and if the search is successful, executing the step S300; and S300, entering a connection initiating state at a preset time point according to the received information sent by the second TWS equipment, and establishing connection with the second TWS equipment. According to the embodiment of the invention, the connection between the TWS master and slave earphones can be established quickly and reliably.

Description

technical field [0001] The present invention relates to TWS technology, in particular to a TWS device connection method and medium. Background technique [0002] With the development of Bluetooth wireless technology, TWS true wireless earphones have become the mainstream of the market. The typical system structure is as follows: image 3 with Figure 4 Two possibilities are shown. [0003] From the perspective of physical structure, the TWS earphone contains two earphones: earphone 1 and earphone 2. From the perspective of role, it includes the master earphone and the slave earphone. The master earphone is directly connected to the smart device (the first link). In order to transmit control information, Audio stream data, etc., the master earphone is connected to the slave earphone at the same time (second link). Has the following characteristics: [0004] 1. The device as the main earphone is random, it may be earphone 1 or earphone 2; [0005] 2. The order of establish...

Problems solved by technology

[0007] 4. For the situation where the first link is established first, and then the second link is established, the status of the slave headset may also be in the state of just starting up, abnormal disconnection after the second link is connected, etc.;

[0008] 5. For two devices connected via standard Bluetooth, it is necessary to set one device as initiating connection, and set the other device as waiting for connection. For earphone 1 and earphone 2, it is impossible to ensure that they are connected at the same time without knowing the state of the other party. , one is initiating a connection and the other is waiting for a connection

[0011] 1. Through the Bluetooth standard connection process, earphone 1 is set to initiate connection, earphone 2 is set to wait for connection (or vice versa), and the main earphone is set to initiate connection. earphone;

[0012] 2. Through the Bluetooth standard connection process, earphone 1 is set to initiate a connection, and earphone 2 is set to wait for connection (or vice versa). If the first link has been established, the role of the earphone connected to the smart device is the master earphone. If earphone 2 Connect with the smart device first, and wait for the headset 1 to connect. If it takes up less bandwidth, the connection will be slow. If it takes up more bandwidth, it will affect the communication between the headset 2 and the smart device;

[0013] 3. Through the Bluetooth standard connection process, both earphone 1 and earphone 2 are in the state of initiating connection and waiting for connection in turn. The disadvantage is that if earphone 1 and earphone 2 are not turned on at the same time, they may be in the state of initiating connection or waiting for connection at the same time. , resulting in failure to connect, or a long connection time
