Abstract
Bluetooth, a wireless short-distance communication technology, realizes data exchange between fixed devices and mobile device. It widely used in wireless devices, including wireless mice, wireless headsets, notebook computers and other devices. With the development of the times, the traditional Bluetooth technology can no longer meet people’s needs, and a new generation of low-power Bluetooth audio technology standards came into being. Bluetooth 5.2 uses LE Audio technology, which uses low-complexity communication coding and decoding technology to realize low-power transmission of high-quality audio. This paper mainly introduces the new features of Bluetooth 5.2 technology, including enhanced ATT protocol, LE Power Control and LE Isochronous Channels.
