Bluetooth

Bluetooth is a wireless communication standard for short-range data exchange between devices, operating in the 2.4 GHz ISM band. It enables connectivity between various electronics like smartphones, headphones, speakers, and IoT devices, supporting both classic and low-energy (BLE) modes for different power and data requirements.

Also known as: BT, BLE, Bluetooth Classic, Bluetooth Low Energy, Bluetooth 5.0
