need help in MCU selection regarding Bluetooth

[Preet]

Dear esteemed members,

I am designing a Bluetooth based small headset kind of application, which will be capable of

1. receiving audio stream, streamed through a device like mobile or any other.
2. also need to control few GPIO with mobile, command will be sent over Bluetooth.
3. also looking for Broadcast mode, so that multiple such headset will be receiving the same stream in future designs.

Kindly let me know about the same

Warm Regards

What kind of "audio stream"?

Note that ST have nothing for Classic Bluetooth - only BLE:

So that means Auracast (LE Audio), then?

Although ST do have Auracast support, note that this is quite new - so a lot of existing BT kit doesn't support it
