title: Use Android device as a headset for another device
body: <p>When I use Bluetooth on my computer, I have a choice of a few different types of devices to look for. One choice is &quot;headset&quot;.</p>
  <p>I want to make an application that will connect to another device as though it is nothing but a headset. So the audio and microphone will route from the Android phone to the other device.</p>
  <p>Is this possible within the Bluetooth API? If so, is the Bluetooth Chat example the best thing to start with for something like this? Most of the information I can find deals with the opposite situation (using an actual headset with an Android device.)</p>
