Bluetooth Speaker profile question

I am interested in using the ReSpeaker Core 2.0 as a Bluetooth microphone and speaker.



In the built-in Bluetooth Speaker slave device mode, do the microphones send audio to the master device?



From what I understand:



If the Bluetooth Speaker mode is using the A2DP Bluetooth profile, then only the speakers will work.



For the mic to also stream back to the master device, the ReSpeaker must use the Bluetooth HFP (Hands Free Profile) or HSP (Handset Profile).



Thanks!

Hi Robert,



In the built-in Bluetooth Speaker slave device mode, do the microphones send audio to the master device? Yes, it sends the merged audio back to master device.



We use both HFP and HSP. thanks.
