//| class Adapter:
//|     """
//|     The BLE Adapter object manages the discovery and connection to other nearby Bluetooth Low Energy devices.
//|     This part of the Bluetooth Low Energy Specification is known as Generic Access Profile (GAP).
//|
//|     Discovery of other devices happens during a scanning process that listens for small packets of
//|     information, known as advertisements, that are broadcast unencrypted. The advertising packets
//|     have two different uses. The first is to broadcast a small piece of data to anyone who cares and
//|     and nothing more. These are known as beacons. The second class of advertisement is to promote
//|     additional functionality available after the devices establish a connection. For example, a
//|     BLE heart rate monitor would advertise that it provides the standard BLE Heart Rate Service.
//|
//|     The Adapter can do both parts of this process: it can scan for other device
//|     advertisements and it can advertise its own data. Furthermore, Adapters can accept incoming
//|     connections and also initiate connections."""
