UDP

I want status update from the devices which communicate on udp, every minute. what method i should use. Any kind of suggestions will be appreciated. Thanks

What I have tried:

I have tried this

foreach (IPAddress ips in iPAddresses)
        {
            Byte[] receiveBytes = { };
            Byte[] dataToSend = new Byte[] { 0x8B, 0xB9, 0x00, 0x03, 0x05, 0x01, 0x09 };
            IPEndPoint endPoint = new IPEndPoint(ips, 1024);
            EndPoint ep = (EndPoint)endPoint;
            Socket udpClient = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);

            try
            {
                udpClient.Connect(endPoint);
                udpClient.SendTo(dataToSend, ep);
               // Thread.Sleep(50);
                IPEndPoint localip = new IPEndPoint(IPAddress.Any, 1200);

                UdpClient receivingUdpClient = new UdpClient(localip);


                receiveBytes = receivingUdpClient.Receive(ref endPoint);
               // Thread.Sleep(50);

                udpClient.Close();


                receivingUdpClient.Close();
                receivingUdpClient.Dispose();
                updateData(receiveBytes, ips);
            }
            finally
            {

                udpClient.Dispose();
            }

        }

The problem I can find is through this line-

receiveBytes = receivingUdpClient.Receive(ref endPoint);

ref endpoint in receive() is having 1st ip address only. its not changing. Send method is able to change ip address. but not receive method.

I have tried some other methods too before this. but this is what I am doing now
