v0.12.0 - 2022-03-03

Added

  • Interface layer to help porting applications to different boards.

Changed

  • Moved most of the code in app/common/ to bsp/interface/.

  • Updated audio applications to account for Audio Core audio_protocol_cfg_t changes.

  • Updated all applications to use the new interface layer.

  • Adjusted output power for most applications.

Removed

  • Removed DESTINATION_ADDRESS and LOCAL_ADDRESS from Ranging application’s STM32CubeIDE project as these are already defined in the source code.

Fixed

  • Fixed an issue that prevented the pairing timeout from occurring in a Node device.

  • Clock drift compensation is now handled correctly in the Audio Core for the Audio 4-Channel application.

  • Audio User Data application needed a hard reset after being programmed for audio to start playing.

  • Audio Compression application could hard fault when starting a debug session in STM32CubeIDE for the first time.
