-//| entries = scanner.scan(2.5)
-//|
-//| my_entry = None
-//| for entry in entries:

-//| my_entry = entry
-//| break
-//|
-//| if not my_entry:
-//| raise Exception("'InterestingPeripheral' not found")
-//|
-//| central = bleio.Central()
-//| central.connect(my_entry.address, 10) # timeout after 10 seconds
-//| remote_services = central.discover_remote_services()
-//|
-
-//| .. class:: Central()
