 As a last demonstration, I'd like to focus on audio streaming over Bluetooth using Opus Kodak. This is a part of Function Pack, which is available in source on ST website. One of the example applications demonstrates full band stereo music streaming from the phone to the STM32WB. The audio is captured in stereo at 48 kHz and after the processing of Opus Kodak, the resulting bitstream is 96 kbps. After the data are received by the WB, it's decoded and sent to the PC over USB, so the PC sees the device as a standard microphone. I would like to point out that Discovery board integrates the STM32WB module. So now let's go to the demonstration. The WB Discovery is flashed with the audio streaming example. On the left, I opened Audacity so that we can visualize the incoming audio data. But we will also be able to hear it, so don't worry. I open STBLE sensor and connect to my device. I can start streaming by simply pressing the play button and as you can hear the audio quality is quite nice.
