title: Is it possible to receive audio from microphone over Bluetooth and play it from device?
body: <p>Android question:</p>
  
  <p>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 ?</p>
  
  <p>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? </p>
  
  <p>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?</p>
  
  <p>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 ;-)</p>
  
  <p>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). </p>
  
  <p>Sincerely thanks, </p>
