//| :class:`Adapter` --- BLE adapter information
//| ----------------------------------------------------
//|
//| Get current status of the BLE adapter
//|
//| Usage::
//|
//|    import bleio
//|    bleio.adapter.enabled = True
//|    print(bleio.adapter.address)
//|

//| .. class:: Adapter()
//|
//|     You cannot create an instance of `bleio.Adapter`.
//|     Use `bleio.adapter` to access the sole instance available.
//|

//|     .. attribute:: adapter.enabled
//|
//|         State of the BLE adapter.
//|

//|     .. attribute:: adapter.address
//|
//|         MAC address of the BLE adapter. (read-only)
