Description
Returns the UUID of the measurement unit of the value of the characteristic that provides the descriptor.
Use GetKnownUnitName to obtain the English name of a unit given its UUID. Bluetooth Low Energy devices may however specify additional, non-standard units using custom UUIDs.
You can only call DoGetFormatUnit if the kind of the descriptor is PresentationFormat.
- Note: This is an abstract method that platform-specific subclasses of TBluetoothGattDescriptor implement.
