title: Initiation of BlueTooth Connection to Android by BlueTooth Device(Master)
body: <p>I have a BlueTooth(BT) device (Master) which must be connected to the android device automatically, after BT device is turned on.
  <br>In my opinion it will be something like BT headset device connection to the android, i.e. while headset turned on - it's automatically initiates connection to android and connects to it. It's not acceptable to create and keep open socket for BT connections on android.</p>
  
  <p> My question is it is possible to do that and how?</p>
  
  <p>If there is some listener/service which run in background of android system and create some event/intent for incoming BT connection, and what is it, and how i can to get information/notification from it? </P>
  In addition it is interesting to know - how android knows that BT headset want to connect - if it receives message/packet or something else?</p>
