We would like to evaluate your STM32WBA55G and nucleo-WBA55CG boards for a project. So we have several questions:
Is it possible to stream BLE audio between two STM32WBA55G boards by taking the sound from the Mems microphone and streaming it to the pc via the USB port (We could see the live audio of the audacity) If so, what examples should we use in your codes?
Is it possible to do the same thing but having the nucleo connected to the PC and which to recover the audio in BLE. We would have the card STM32WBA55G further away that would be streaming the audio by picking up the audio from its microphone
Is it possible to connect a STM32WBA55G to an nRF5340 Audio via BLE audio?
I guess you are speaking about the STM32WBA55G-DK1 board.
So here are few answers
It depends on your needs: current projects don't use the MEMS but drivers support it. You could update the application to source audio from the MEMS. However, the most difficult part is the connection to the PC since the WBA55 doesn't support USB protocol. The USB connector is for the STLink and maybe the VCP (UART) could be used to send audio to the PC, but it's a non-synchronous, non-audio standard and baudrate limited bus. Either PBP (simplest) or TMAP (in media mode) could be used as a starting point.
Same problem as above: you can remove BSP from the DK project to use on a Nucleo board however the connection to the PC is the trickiest things
Yes, they are interoperable (at the protocol level) but the application may need to be adapted
Is it a correct assumption to consider the STM32WBA55G-DK1 Board as a kind of superset for the Nucleo-WBA55CG Board? Demos and other software codes written for the Nucleo-WBA55CG Board should be portable to the STM32WBA55G-DK1 Board if the functions related to the buttons are changed to be suitable for the joystick.
Yes, totally, and both references are using MB1803 (MCU RF board with the STM32WBA55CG). Only the mother board changes and the DK have more components / functionalities.
