1. Bluetooth principle--Introduction
Bluetooth is a radio technology that enables devices to communicate over short distances. Wireless information exchange can be performed between many devices including mobile phones, PDAs, wireless headsets, notebook computers, and related peripherals. Bluetooth currently has V1.1, V1.2, and V2.0 standards in the field of mobile phones. The disadvantages and advantages of wireless Bluetooth of the Bluetooth 1.1 standard are equally obvious. In the latest Bluetooth 1.2 device standard announced by the Bluetooth SIG, the newly released 1.2 standard provides better co-channel anti-jamming capability, strengthens language recognition capability, and is backward compatible with 1.1 devices. www.bjbjaudio.com

2. Bluetooth principle--features
Both Bluetooth and infrared are used for wireless data transmission and information exchange. Infrared can only transmit data from a small angle, point-to-point straight line, and has strong security, but the speed is slow, the communication distance is short, it cannot move during the communication process, and the communication is interrupted when encountering obstacles. The Bluetooth technology is much more advanced than infrared, with fast speed, long communication distance, and is not blocked by obstacles. www.bjbjaudio.com

3. Bluetooth principle
Bluetooth is a short-range radio connection system that can link different electronic devices together. The principle is just like a radio, an electronic device equipped with Bluetooth can receive external information to carry out specific instructions. However, Bluetooth can not only receive, but also "transmit", so electronic equipment equipped with Bluetooth can communicate with each other. For example, a mobile phone cannot "go online" to receive e-mail if it is not connected to a telephone line, but with the help of Bluetooth, users can Do "wireless" Internet access. www.bjbjaudio.com

4. Bluetooth principle - application
Bluetooth mobile phones can not only surf the Internet, but also wirelessly connect with laptops within a certain range, making wireless Internet access for laptops a reality; for two users who hold Bluetooth mobile phones at the same time, they can exchange business cards, phone calls and mobile phone ringtones through their mobile phones. You can also play wirelessly. Within a 10-meter range, simply put on a Bluetooth headset and receive calls wirelessly in the car or in the office. The bluetooth function of the mobile phone will eventually replace the infrared of the chicken flank. www.bjbjaudio.com
