Bluetooth function is a radio technology that supports short-distance communication between devices (generally within 1m). It can exchange wireless information among many devices, including mobile phones, PDA, wireless headphones, notebook computers, related peripherals and so on. The standard of Bluetooth is IEEE82.15, which works in 2.4GHz band and has a bandwidth of 1 MB/s.. Bluetooth supports voice and data transmission; Using radio technology, the transmission range is large, which can penetrate different substances and spread among substances; Using frequency hopping spread spectrum technology, it has strong anti-interference and is not easy to eavesdrop; In theory, there is no interference problem when using spectrum that is unrestricted in all countries; Low power consumption; Low cost.
