Audio on STM32WB55CG?

Hello @STTwo-32 ! Thank you so much for clarifying everything! I am really thrilled with the STM32WBA Nucleo board. Could you please let me know, if it is compatible with the FP-AUD-BVLINKWB1 pack? If not, are there any code examples on how to implement Bluetooth audio on it? Such as pairing with headphones et cetera?

Hello @Skfir 

As said @Andrew Neil The STM32WB/WBA does not support Bluetooth Classic, which is the technology used by AirPods for audio streaming. The STM32WBA supports BLE (Bluetooth Low Energy) Audio features, which are different from the Bluetooth Classic used by AirPods.

If you are looking to implement audio streaming applications similar to True Wireless Stereo (TWS) using BLE, the STM32WBA can be a suitable choice, but it will not be compatible with AirPods.

For the FP-AUD-BVLINKWB1 it is compatible only with the STM32WB. And for test of the Audio.L.E. The Nucleo board may not do the job. You need to use the DK board.

Best Regards.

The STM32WBA is BLE only - so it won't work with things which only do "Classic" BT audio ...

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

      Just a followup question, since I don't know much about bluetooth in general. Do all the generations of AirPods use Bluetooth Classic? I mean, if I use STM32WB/WBA, will I lose compatibility with all the generations of AirPods, or just the first one?
