Properties

AttributeHandle	Gets the GATT Attribute handle used to uniquely identify this attribute on the GATT Server Device.
ProtectionLevel	Gets or sets the desired GATT security options for over the air communication with the device. Windows will negotiate the maximum security possible with the device as part of the pairing process, and specifying a lower level of security won’t degrade the existing security level.
Uuid	Gets the GATT Descriptor UUID for this GattDescriptor.

Methods

ConvertShortIdToUuid(UInt16)	Converts a Bluetooth SIG defined short Id to a full GATT UUID. Important The ConvertShortIdToUuid API is deprecated, and it may not be available in future versions of Windows. Instead, use BluetoothUuidHelper.FromShortId.
ReadValueAsync()	Performs a Descriptor Value read from a value cache maintained by Windows.
ReadValueAsync(BluetoothCacheMode)	Performs a Descriptor Value read either from the value cache maintained by Windows, or directly from the device.
WriteValueAsync(IBuffer)	Performs a Descriptor Value write to a Bluetooth LE device.
WriteValueWithResultAsync(IBuffer)	Performs a Descriptor Value write to a Bluetooth LE device.
