title: Android Bluetooth Pairing
body: <p><br>
  Can anybody tell me how to find out which pairing technique phone used while connecting to other device?<br>
  I have a Nexus S(Android 2.3.3) and a BT device(Bluetooth2.1+EDR).<br>
  When I try to pair them, I dont have to give any input(passkey). As both devices are having bluetooth 2.1, I want to know which pairing technique they used.<br>
  Can we specify the pairing technique to phone?</p>
