title: Android Bluetooth Quick Device Discovery
body: <p>I am developing an Bluetooth 4.0 Low Energy application to scan surrounding advertise-only device quickly (10 times or more per second) and get their address with RSSI.
  According to <a href="http://developer.android.com/reference/android/bluetooth/BluetoothAdapter.html#startDiscovery%28%29" rel="nofollow">Android Bluetooth API</a>, the discovery is asynchronous and takes around 12 seconds. Is there any way to set this time? Or is it possible to directly communicate with the device using HCI or the Bluetooth stack?</p>
