//       allows user to add/remove Bluetooth adapter.
// Currently, B2G recognizes build-in Bluetooth chip as default adapter and
// don't support adding additional Bluetooth dongles in gonk layer.
// Therefore, the 'onattributechanged' would be triggered *only* when the
// instance of BluetoothManager is created.
