Application of bluetooth technology tws earbuds connection

1. Walkie-talkie
In the future, the mobile phone using Bluetooth technology will be "three-in-one", that is, it integrates three functions of mobile phone, cordless phone and walkie-talkie. A direct voice channel can be established between two Bluetooth devices within a short distance. For example, between two cellular phone users, a direct conversation can be conducted through a Bluetooth connection, so that the mobile phone can be used as a walkie-talkie. www.bjbjaudio.com    <a style="opacity:0.0;color:#ffffff">tws earbuds connection</a>   <a style="opacity:0.0;color:#ffffff">tws earbuds connection</a>

2. Cordless phone
The mobile phone with built-in Bluetooth chip can be used as a cordless phone indoors, and can be connected to PSTN for voice transmission through the base station of the cordless phone, so that there is no need to pay for expensive mobile calls. Of course, it is still used as a mobile phone port outdoors or on the way. This application model defines two device roles; gateway and terminal. The gateway serves as the end point for the external network and handles all traffic to this network. For external calls, the gateway is the center that handles all call setup requests to or from the external network. The gateway role can be a PSTN or ISDN home base station, a GSM base station, a satellite base station or an H.323 base station. www.bjbjaudio.com      <a style="opacity:0.0;color:#ffffff">tws earbuds connection</a>

Gateways can be divided into two categories: one can support multiple active terminals at the same time, and the other type only supports a single active terminal at the same time. The terminal may be a cordless phone, a cellular phone or a multimedia PC. In this application mode, both connection-oriented and connectionless channels are used,   
The connectionless channel is mainly used for the gateway to send broadcast information to the terminal, and only the gateway can use the connectionless channel to send information. www.bjbjaudio.com

3. Headphones
Headphones using Bluetooth technology can be used as voice input and output interfaces for mobile phones, personal computers, etc., while maintaining private conversations, allowing users to get rid of the shackles of cables and have greater freedom of movement. This kind of headset must be able to send AT commands and receive corresponding encoded signals, so that the user can complete operations such as picking and hanging up without manual operation. www.bjbjaudio.com   <a style="opacity:0.0;color:#ffffff">tws earbuds connection</a>

4. Dial-Up Networking
Devices such as mobile phones and Modem using Bluetooth technology can be used as "Internet bridges". For example, the mobile phone can be used as a wireless modem for a computer to access a dial-up network server, or the computer can receive data through the mobile phone or the modem. At this time, the mobile phone and Modem act as gateways to provide access to the public network, while desktop computers or notebook computers act as data terminals and use the services provided by the gateway. www.bjbjaudio.com   <a style="opacity:0.0;color:#ffffff">tws earbuds connection</a>
