+//| :class:`Central` -- A BLE central device
+//| =========================================================
+//|
+//| Implement a BLE central, which runs locally. Can connect to a given address.
+//|
+//| Usage::
+//|
+//|    import bleio
+//|
+//|    scanner = bleio.Scanner()
+//|    entries = scanner.scan(2.5)
+//|
+//|    my_entry = None
+//|    for entry in entries:
+//|        if entry.name is not None and entry.name == 'MyCentral':
+//|            my_entry = entry
+//|            break
+//|
+//|    central = bleio.Central(my_entry.address)
+//|    central.connect()
+//|
+
+//| .. class:: Central(address=None, scan_entry=None)
+//|
+//|   Create a new Central object. If the `address` or :py:data:`scan_entry` parameters are not `None`,
+//|   the role is set to Central, otherwise it's set to Peripheral.
+//|
+//|   :param bleio.Address address: The address of the central to connect to
+//|   :param bleio.ScanEntry scan_entry: The scan entry returned from `bleio.Scanner`
