udp send and receive

[yyy898]

hi all, i have a program that needs bi directional comunication with a device i bought,
i can send udp commands to it, thats working like a charm, but when i try to receive data from it i can only see the data that im sending, not the response,
my code:

 Public udpClient As New UdpClient(11000)
 Public udpClient2 As New UdpClient(52380)
 Private Sub Hoofd_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        udpClient.Connect("255.255.255.255", 52380)
        udp_scan.Start()
        udpClient2.Client.ReceiveTimeout = 1000
    End Sub

Private Sub udp_scan_Tick(sender As Object, e As EventArgs) Handles udp_scan.Tick
        info_label.Text = "ZOEKEN..."
        Dim sendbytes = New Byte() {&H2, &H45, &H4E, &H51, &H3A, &H6E, &H65, &H74, &H77, &H6F, &H72, &H6B, &HFF, &H3}
        udpClient.Send(sendbytes, sendbytes.Length)
        doread()
    End Sub

Function doread()
        Try
            Dim iepRemoteEndPoint As IPEndPoint = New _
            IPEndPoint(IPAddress.Any, 52380)
            Dim strMessage As String = String.Empty
            Do


                Dim bytRecieved As Byte() =
               udpClient2.Receive(iepRemoteEndPoint)
                strMessage = Encoding.ASCII.GetString(bytRecieved)

                Console.WriteLine("This is the message you received: " _
               + strMessage)

            Loop While (strMessage <> "exit")
            udpClient2.Close()


        Catch e As Exception

            Console.WriteLine(e.ToString())
        End Try
        Return 0
    End Function

in wireshark i can see both the data i send and the response, in my program i only receive what im sending not the response.
