Receiving and Playing Bluetooth Audio?

earphone jack = audio out, not audio in.

Yes I know, I want to stream audio over bluetooth to phone and play it OUT of the headphone socket, can this be done?

Well this does pose multiple questions. First thing is how can you decode the audio stream from the bluetooth device. First try saving the stream to file and see what you get.

Trouble is I am a total noob and don't know where to start.

There is an Android app called airbubble that uses the phone as a wireless receiver although this seems to play audio which has been wifi streamed to it from a Mac or Windows PC acting as a server.

Its not quite what I want but heading in the right direction.

I have a bluetooth transmitter which is sending audio (I think it uses a headset profile or can use A2DP), normally you would pair this with a bluetooth headset, so in effect the bluetooth is just a virtual audio cable.

I want to use the Android phone in place of the headset so the virtual audio cable connects from the BT transmitter to the phone, I would then like to be able to listen to this audio using wired earphones plugged into the phone jack socket, it would also be nice to record the audio to SD card as well.

I dont think an Android device can be used as an A2DP Sink.
and I cannot find much information about how to do it either.
There is some talk of the BlueZ bluetooth stack in current versions of Android not supporting this (however if they upgraded to the latest version it is possible).

After a bit of a google I found a few things that imply BlueZ can act as an A2DP sink, I found this article from 2 years ago:-

BlueZ now has A2DP Sink support | jprvita’s weblog

It still leaves me none the wiser as where to even start with this

Any Ideas?

Maybe Gingerbread uses 4.64 so it may be possible.
However I cannot find any information on whether the Android OS exposes this functionality in the API.
