The btleService type is used to handle a Bluetooth Low Energy service ("Bluetooth GATT Service").

Each Bluetooth LE service is identified by a unique character string (UUID) and it contains a set of characteristics. A list of different standard services can be found on the site https://www.bluetooth.com/specifications/gatt/services.
For more details about the standard specifications, see: https://www.bluetooth.com/specifications/protocol-specifications.

Bluetooth LE service features can be defined and modified using various WLanguage properties.
