title: Android App Bluetooth Determining distance between paired devices
body: <p>so I'm trying my hand at android developing this summer. I was trying to make a sort of alarm app when a pair of connected devices go out of range of each other.</p>
  
  <p>From looking around on the internet / stack overflow, it seems that looking at the RSSI value will help me achieve this.</p>
  
  <p>However, it seems that the RSSI value can only be read at the time of connection with the device, that is it doesn't update itself (or there is no method to do so).</p>
  
  <ol>
  <li>Is the RSSI value the only way to achieve my goal?</li>
  <li>Would it be possible to use <a href="http://snapshot.bluecove.org/bluecove/apidocs/javax/bluetooth/RemoteDevice.html" rel="nofollow">RemoteDevice</a> and <a href="http://snapshot.bluecove.org/bluecove/apidocs/com/intel/bluetooth/RemoteDeviceHelper.html#readRSSI%28javax.bluetooth.RemoteDevice%29" rel="nofollow">RemoteDeviceHelper</a>? Has anyone tried this?</li>
  <li>Any other suggestions and hints would be much appreciated</li>
  </ol>
