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.

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.
