- | Bluetooth Low Energy (LE) is a wireless protocol transmitting at 2.4 GHz. It's designed and promoted by the [[https://www.bluetooth.com/|Bluetooth SIG]]. Bluetooth LE is separate to and not compatible with the previous 'Classic' Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR) protocol. Unlike Classic Bluetooth, devices do not have to pair. The Bluetooth 4.0 and Bluetooth 5.0 [[specifications|specifications]] allow devices to implement both LE and BR/EDR protocols on the same device. | + | Bluetooth Low Energy (LE) is a wireless protocol transmitting at 2.4 GHz.
