Abstract
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.
Highlights
Bluetooth is a short-distance wireless data communication technology, which can connect multiple devices at the same time
Data transmission by frequency hopping spread spectrum technology has high security and antiinterference ability, and establishes data transmission channels for fixed and mobile devices. It widely used in mobile phones, wireless headsets, notebook computers, automobiles and other related external devices [2]
Using Bluetooth technology, a connection channel can be established between fixed devices or mobile devices within an effective range, which is essentially to establish a universal Radio Air Interface for the communication environment between various devices, further combining communication technology with computer technology, and carrying out data intercommunication transmission without cables
Summary
Bluetooth is a short-distance wireless data communication technology, which can connect multiple devices at the same time. It has the characteristics of low cost, fast speed, convenient use and low power consumption [1]. Data transmission by frequency hopping spread spectrum technology has high security and antiinterference ability, and establishes data transmission channels for fixed and mobile devices. It widely used in mobile phones, wireless headsets, notebook computers, automobiles and other related external devices [2]. This paper mainly introduces the new features of Bluetooth 5.2, mainly introduces the Enhanced Attribute Protocol (EATT), LE Power Control and LE Isochronous Channels technology
