How to make an Android phone as a Bluetooth headset

Question

I have 2 Android phones and I want to pair them together via Bluetooth and make one of them a bluetooth headset.

So my question is how to set up a second phone to change its role profile to a “Bluetooth headset” when establishing a connection?

I found this post , but my question is a little different

Thanks for any tips or ideas :)

Answer 1

You cannot on Android. At least using the built-in Bluetooth A2DP .

Your phone will only act as a transmitter (source), not a receiver (receiver).

Please look at these two answers that I gave, why this is not possible:

• Is it possible to send / receive voice from a PC to an Android device via Bluetooth .

• Get audio via Bluetooth in Android

On the other hand, you can develop two applications, each of which acts as a client / server using its own protocol. For example, a server can broadcast audio content to a client via Bluetooth.

Another way to consider this, since using an Android device as an A2DP sink not possible on every phone, is to create these two applications using your Wi-Fi connection. It can be much faster and the sound will be much better.
