title: Android Bluetooth Low Energy readRemoteRssi
body: <p>I can't figure out how to get the 'onReadRemoteRssi' callback work.</p>
  
  <p>My code is very simple :</p>
  
  <pre><code>final BluetoothManager bluetoothManager = (BluetoothManager) getSystemService(Context.BLUETOOTH_SERVICE);
      BluetoothAdapter mBluetoothAdapter = bluetoothManager.getAdapter();
      BluetoothGatt gatt;
  
      mBluetoothAdapter.startLeScan(new LeScanCallback() {
  
          @Override
          public void onLeScan(BluetoothDevice device, int rssi, byte[] record) {
              gatt = device.connectGatt(getApplicationContext(), false, new BluetoothGattCallback() {
                  @Override
                  public void onReadRemoteRssi(BluetoothGatt gatt, int rssi, int status) {
                      super.onReadRemoteRssi(gatt, rssi, status);
                      Log.d(TAG, "rssi is : " + rssi);
                  }
              });
          }
      });
  
      gatt.readRemoteRssi(); //returns true
  </code></pre>
  
  <p>The callback is never called.
  Does anyone have any idea ? </p>
  
  <p>Thanks !</p>
