Bluetooth Standards

All Bluetooth standard versions with speeds, features, and compatibility.

Bluetooth standards provide short-range wireless connectivity for audio, peripherals, and IoT devices. Bluetooth 5.0 quadrupled range and doubled speed over 4.2, while Bluetooth 5.3 improved reliability for LE Audio. The LC3 codec in LE Audio delivers CD-quality audio at half the bitrate of SBC. Bluetooth Auracast enables broadcast audio to unlimited receivers — transforming public venues, hearing aids, and personal audio sharing.
