GattCharacteristic.ReadValueAsync Method

Definition

Overloads

ReadValueAsync()

Performs a Characteristic Value read from the value cache maintained by Windows.

ReadValueAsync(BluetoothCacheMode)

Performs a Characteristic Value read either from the value cache maintained by Windows, or directly from the device.

ReadValueAsync()

Performs a Characteristic Value read from the value cache maintained by Windows.

public IAsyncOperation<GattReadResult> ReadValueAsync();
function readValueAsync()
Public Function ReadValueAsync () As IAsyncOperation(Of GattReadResult)

Returns

IAsyncOperation<GattReadResult>

The object required to manage the asynchronous operation, which, upon completion, returns a GattReadResult object, which in turn contains the completion status of the asynchronous operation and, if successful, the data read from the device.
