Is it possible to receive audio from microphone over Bluetooth and play it from device?

Android question:

Is there any way I can use a Bluetooth microphone to live stream audio speech and play the audio real-time through the speakers of my phone ?

NOTE: I am aware that there is concepts of Sink and Source in such streaming - is this also the case, as my microphone takes the role of a Source and my smartphone the role of a Sink? Or is this a whole different scenario altogether?

I am also aware there typically are used two different kinds of Bluetooth Profiles: Advanced Audio Distribtion Profile (A2DP) and Handsfree-Headset Profile (HFP). I'm guessing then only A2DP is relevant in this situation as it regards audio streaming and HFP is used only for heands-free phonecalling, right?

The idead is I would be able to speak through a Bluetooth microphone and then hear the speech real-time through the speakers of my phone - like a one-way radio system ;-)

I am not looking for a complete code or anything, merely an answer to whether this is acutally possible? (And then a maybe a fingers-point in the right direction).

Sincerely thanks,

David

As you mentioned, Classic BT allows bidirectional conversation.

I have not tried this way but of-course you can try changing in-built Audio profile at time you need.

Please give it a hit and let me know in case it works for you.
