    Question

  •  private static readonly Guid RfcommChatServiceUuid = Guid.Parse("e0cbf06c-cd8b-4647-bb8a-263b43f0f974");

            private const UInt16 SdpServiceNameAttributeId = 0x100;
            private const byte SdpServiceNameAttributeType = (4 << 3) | 5;

            private const string SdpServiceName = "Bluetooth Rfcomm Chat Service";

            private StreamSocket socket;
            private DataWriter writer;
            private RfcommServiceProvider rfcommProvider;
            private StreamSocketListener socketListener; 

    here is Rfcomm intilization method

    rfcommProvider = await RfcommServiceProvider.CreateAsync(RfcommServiceId.FromUuid(RfcommChatServiceUuid));
                   
                    socketListener = new StreamSocketListener();
                    socketListener.ConnectionReceived += OnConnectionReceived;
                   await socketListener.BindServiceNameAsync(rfcommProvider.ServiceId.AsString(),
                        SocketProtectionLevel.BluetoothEncryptionAllowNullAuthentication);/*am getting access violation exception in this line*/
                   
                    // Set the SDP attributes and start Bluetooth advertising 
                    InitializeServiceSdpAttributes(rfcommProvider);
                    rfcommProvider.StartAdvertising(socketListener);

  • Hello Mahesh,

    Since this issue is related with windows store app, i would ask the moderator to help move it to the appropriate forum, the current form you post to is used to discuss general issues about developing applications for Windows.
