Tranciever circuit to interface with "off the shelf" BT headset.

[delambo]

As per the title I am looking for a circuit to interface any standard bluetooth headset (for mobile phones) with any audio equipment. I want a transceiver to receive audio from the microphone in the headset and output it via a jack plug to a recording device, and to receive audio from a playback device via a jack plug to be transmitted to the bluetooth headset.

I have done some research but having never had anything to do with bluetooth whatsoever it all seems a bit of a minefield!!

What I am looking for is pretty much exactly **broken link removed**!! Infact if it was availale to buy somewhere I would buy it and modify the jack plug for the application I want.

Still maybe it will help to understand what I want to achieve.
