Namespace: InTheHand.Net.Bluetooth.Sdp
Assembly: InTheHand.Net.Bluetooth (in InTheHand.Net.Bluetooth.dll) Version: 4.0.32+5cdf1cfd21064ea31c5de33d160200ca1c4bc218

C#

public static ServiceElement CreateL2CapProtocolDescriptorListWithUpperLayers(
	params ServiceElement[] upperLayers
)

VB

Public Shared Function CreateL2CapProtocolDescriptorListWithUpperLayers ( 
	ParamArray upperLayers As ServiceElement()
) As ServiceElement

C++

public:
static ServiceElement^ CreateL2CapProtocolDescriptorListWithUpperLayers(
	... array<ServiceElement^>^ upperLayers
)

F#

static member CreateL2CapProtocolDescriptorListWithUpperLayers : 
        upperLayers : ServiceElement[] -> ServiceElement

Parameters

upperLayers ServiceElement: The list of upper layer elements, one per layer. As an array.

Return Value

ServiceElement
The new ServiceElement.

Remarks

Thus is the following structure at the first layer:

ElementSequence
   ElementSequence
      Uuid16 = L2CAP
      UInt16 = 0      -- The L2CAP PSM Number.

One can add layers above that; remember that all layers are formed of an ElementSequence. See the example below.

Example

C#

var netProtoList = new ServiceElement(ElementType.ElementSequence,
    ServiceElement.CreateNumericalServiceElement(ElementType.UInt16, 0x0800),
    ServiceElement.CreateNumericalServiceElement(ElementType.UInt16, 0x0806)
    );
var layer1 = new ServiceElement(ElementType.ElementSequence,
    new ServiceElement(ElementType.Uuid16, Uuid16_BnepProto),
    ServiceElement.CreateNumericalServiceElement(ElementType.UInt16, 0x0100), //v1.0
    netProtoList
    );
ServiceElement element = ServiceRecordHelper.CreateL2CapProtocolDescriptorListWithUpperLayers(
    layer1);
