//|
//| :class:`Scanner` -- scan for nearby BLE devices
//| =========================================================
//|
//| Allows scanning for nearby BLE devices.
//|
//| Usage::
//|
//| import bleio
//| scanner = bleio.Scanner()
//| entries = scanner.scan(2500)
//| print(entries)
//|
//| .. class:: Scanner()
//|
//| Create a new Scanner object.
//|
//| .. attribute:: interval
//|
//| The interval (in ms) between the start of two consecutive scan windows.
//| Allowed values are between 10ms and 10.24 sec.
//|
//| .. attribute:: window
//|
//| The duration (in ms) in which a single BLE channel is scanned.
//| Allowed values are between 10ms and 10.24 sec.
//|
//| .. method:: scan(timeout)
//|
