Definition

Overloads

ReadValueAsync() ReadValueAsync() ReadValueAsync() ReadValueAsync() ReadValueAsync()

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

ReadValueAsync(BluetoothCacheMode) ReadValueAsync(BluetoothCacheMode) ReadValueAsync(BluetoothCacheMode) ReadValueAsync(BluetoothCacheMode) ReadValueAsync(BluetoothCacheMode)

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

ReadValueAsync() ReadValueAsync() ReadValueAsync() ReadValueAsync() ReadValueAsync()

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

public : IAsyncOperation<GattReadResult> ReadValueAsync()
IAsyncOperation<GattReadResult> ReadValueAsync() const;
public IAsyncOperation<GattReadResult> ReadValueAsync()
Public Function ReadValueAsync() As IAsyncOperation(Of GattReadResult)
Windows.Devices.Bluetooth.GenericAttributeProfile.GattCharacteristic.readValueAsync().done( /* Your success and error handlers */ );

Returns

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.
