title: Continual Bluetooth LE Signal Strength on Android
body: <p>Can anyone suggest how to continually read BT4-LE Signal Strength on Android API Level 18+ as to detect relative proximity to BT-LE beacons?   I know that LE radio signal strength is returned during scanning (see: <a href="http://developer.android.com/reference/android/bluetooth/BluetoothAdapter.LeScanCallback.html" rel="nofollow">http://developer.android.com/reference/android/bluetooth/BluetoothAdapter.LeScanCallback.html</a>), but once scanning is complete and a connection is established is there anyway to get the updated BT-LE signal strength without rescanning?</p>
