SDK

v1.1.0 - 2022-11-30

Added

  • Statistics printed every second in Audio High Resolution, Audio Compression, Audio 4-Channel, Audio Mixer, Audio Streaming and Audio User Data.

  • Build configuration for dual radio in the Hello-World STM32CubeIDE project. Note that the dual radio feature requires a custom board with two SPARK transceivers.

Changed

  • Enable clear channel assessment (CCA) in the Audio Compression application.

  • Audio processing is now handled in a low priority timer’s interrupt service routine in Audio High Resolution, Audio Compression, Audio 4-Channel, Audio Mixer, Audio Streaming and Audio User Data to make sure the statistics computing and printing (which occur in background) do not interfere with it.

  • Update all applications for Wireless Core changes. See Wireless Core changelog for more details.

  • Update all audio applications for Audio Core changes. See Audio Core changelog for more details.

  • Code for pairing has moved from app/common/ to the Wireless Core core/wireless/pairing/.

Removed

  • Common code folder app/common/.

  • Deprecated audio interface function iface_audio_critical_section_init(). Critical section functions are now set through iface_sac_hal_init().

Fixed

  • Coding style issues.

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.
