Innovative functions of Bluetooth communication between smartphones and information appliances

Bluetooth technology, in short, is a wireless communication technology used to support short-distance communication between devices, usually effective within 10 meters. This technology has been widely used in mobile phones\PDAs\wireless headsets\laptops and other related peripherals and other devices, realizing wireless information exchange between them. The application of Bluetooth technology not only simplifies the communication between mobile communication devices, but also provides a convenient wireless data transmission method, and also speeds up the speed of the device. Communication with the Internet has greatly expanded the application fields of wireless communications.

Bluetooth technology is an advanced technology designed for short-distance wireless connections. It can transmit data and voice in a convenient, efficient, safe, economical, and low-power manner. Therefore, it is widely considered to be the key to supporting wireless personalization. One of the main technologies for area network communication. Although the original design goal was to replace infrared communication, Bluetooth technology has now become an important wireless communication standard with a wide range of application prospects.

The core concept of Bluetooth technology is to establish a universal radio air interface based on low-cost short-range wireless connections and integrate communication technology with computer technology. This enables various 3C devices to communicate or operate with each other within a short range without the need for Wire or cable connection. In short, Bluetooth technology is a low-power wireless data transmission technology that operates in the globally common 2.4GHz ISM band and adopts the IEEE 802.15 protocol. Bluetooth technology actively promotes the development of low-rate wireless personal area networks .

Bluetooth technology has many applications in smart homes:
