Bluetooth technology was originally developed to simplify and improve data transmission between devices. Bluetooth module can be embedded in various electronic devices, such as smart phones, tablets, computers, audio devices, auto parts, sensors and industrial equipment. It allows these devices to communicate within a relatively short distance (usually 10 meter) without using a traditional wired connection.
Bluetooth module usually includes the following main components and functions:
Bluetooth chip: integrates the hardware and software functions such as RF circuit, modem and protocol stack required for Bluetooth communication.
Antenna: used to send and receive Bluetooth signals.
Interface: used to connect and communicate with other devices or host systems. Common interfaces include UART (serial port), SPI (serial peripheral interface) and I2C (serial bus interface).
Driver and protocol stack: used to manage Bluetooth communication, data transmission and interaction with other devices.
Through the Bluetooth module, devices can realize wireless audio transmission, data synchronization, remote control, sensor data acquisition and interconnection between devices. The development of Bluetooth module makes the connection between devices more convenient, and provides important technical support for the intelligent and wireless interaction between devices.
