BLE module for audio streaming that can be operated using commands (i.e. no programming)

[Ricko]

Hi,

is there any ST Bluetooth BLE module that can stream audio (preferably high quality) and that can be fully operated just by using commands (like AT or other/proprietary commands)?

Ideally for it to have a analog output pin/signal we can connect to a low power amplifier, but it can also be an I2C or other.

Thank you

Hello @Ricko 

For the Audio LE, I suggest you check on the STM32WBA series (take a look at this page specially the Discover our portfolio paragraph). But for a Module we have only the STM32WBA5M. It is not commanded directly throw the AT Commands (as it is) but you may program it with your own SW that make it configurable throw AT Commands.

Best Regards.

Thank you @STTwo-32 

it does not need to be AT commands. The reason for asking about that is that usually is the fastest way to setup and develop a product for audio streaming (we don't have any experience of Bluetooth). Both speed of development and simplicity of development (software wise) are the priority.

Bearing that in mind could you please explain:

1) if all we want to do is:

              - connect to a mobile phone and

              - stream audio from a mobile phone

              - ensure auto-reconnect if the phone moves out of range (when it comes back into range)

    then how simple is it to implement? And how fast (considering we are familiar with STM32 family and software)?

    Just to get a feel for it... a couple of days... weeks... months...? just a rough guideline.

2) how reliable is auto-reconnect? The ESP32-WROOM for example when it disconnects it sometimes does not auto-reconnect reliably. Assuming obviously there is full signal between the ST Micro module and the device, is auto-re-connection 100% reliable?

Thank you

Remember that most phones (and other devices) today do not support LE Audio - only BT Classic audio.

I can't give you an exact period since i didn't tested on my side. But i think with a team that used to program on STM32 MCUs (specially the Wireless products), it will not take long time. For the auto-reconnect, i suggest you test it on your side using your own FW to make sure that it is working well. Note that the ESP32-WROOM use the classic Bluetooth and the STM32 wireless products implement only BLE, and those two technologies are not compatible (as said @Andrew Neil). 

Best Regards.
