Voice Over BLE – Make audio streaming via Bluetooth® Smart possible

The “Voice over BLE” library implements a GATT specific profile based on the very low power Bluetooth Low Energy (BLE) specifications and aims to relay voice over the BLE radio link.

 

Key features

  • The G726 default CODEC can be negociated at startup of the communication
  • Half-duplex communication profile
  • Designed for applications using digital MEMS microphones
  • Easy portability across different architecture

The Voice Over BLE defines two roles: the TRANSMITTER and the RECEIVER.

  • The TRANSMITTER is the device which acts as the “microphone side” and sends the voice data to a device named RECEIVER.
  • The RECEIVER is the device that receives the voice data over the air from the RECEIVER and outputs it.
