STM32WBA55G-DK1 not compatible with all mobiles

Pallavi · ‎2024-07-22

Hi
I recently purchased DK board and connected to the phone to check the dumped code.
But, I couldn't listen to any music nor call.

I realised only few selected mobiles with BLE Audio can be used to test the board.
Any solution to this?

Thanks in advance!

Hi @Andrew Neil

Thank you. Got it!
I have understood that only few mobiles with BLE feature can be used to test the Audio features as mentioned in

The ST Chips do BLE only; they do not do "Classic" Bluetooth - so you obviously won't be able to use them with phones which only have classic Bluetooth!

You will need a separate Classic BT module to support Classic BT.

Yes, Auracast (LE Audio) is a very new BLE feature (only released this year?) - so very few phones yet support it.

Please mark the solution.
