How to scan for available bluetooth devices in range in android?

Question

I need to get a list of available bluetooth devices in the area using google android 2.1.

Thing is, i don't just need a list of those devices, i need some unique id for each device found and i need an indicator, how "good" the signal is received (like the "level" in android.wifi.ScanResult)... How do i do that?

Check out code below :

Starting search

mBluetoothAdapter.startDiscovery(); 
mReceiver = new BroadcastReceiver() {
public void onReceive(Context context, Intent intent) {
    String action = intent.getAction();

    //Finding devices                 
    if (BluetoothDevice.ACTION_FOUND.equals(action)) 
    {
        // Get the BluetoothDevice object from the Intent
        BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
        // Add the name and address to an array adapter to show in a ListView
       mArrayAdapter.add(device.getName() + "\n" + device.getAddress());
    }
  }
};

IntentFilter filter = new IntentFilter(BluetoothDevice.ACTION_FOUND); 
registerReceiver(mReceiver, filter);
