btleService (Type of variable)

In french: btleService

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.

The characteristics of Bluetooth LE service can be defined and modified by several WLanguage properties.

Remark: For more details on the declaration of this type of variable and the use of WLanguage properties, see Declaring a variable.

myDevice is btleDevice
myService is btleService <- myDevice.Service[1]
