GattCharacteristic.ReadValueAsync Method

Definition

Namespace:

Windows.Devices.Bluetooth.GenericAttributeProfile

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:
 virtual IAsyncOperation<GattReadResult ^> ^ ReadValueAsync() = ReadValueAsync;

/// [Windows.Foundation.Metadata.Overload("ReadValueAsync")]
/// [Windows.Foundation.Metadata.RemoteAsync]
IAsyncOperation<GattReadResult> ReadValueAsync();

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.

ReadValueAsync(BluetoothCacheMode)

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

public:
 virtual IAsyncOperation<GattReadResult ^> ^ ReadValueAsync(BluetoothCacheMode cacheMode) = ReadValueAsync;

/// [Windows.Foundation.Metadata.Overload("ReadValueWithCacheModeAsync")]

public IAsyncOperation<GattReadResult> ReadValueAsync(BluetoothCacheMode cacheMode);

function readValueAsync(cacheMode)

Public Function ReadValueAsync (cacheMode As BluetoothCacheMode) As IAsyncOperation(Of GattReadResult)

Parameters

cacheMode

BluetoothCacheMode

Specifies whether to read the value directly from the device or from a value cache maintained by Windows.

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.
