Получение UDP от Arduino Board

/ 01 мая 2020

Я использую этот класс для получения данных с платы Arduino со щитом rnet. Он застрял в строке "byte [] receiveBytes = clientReturn.Receive (ref receiveEndPoint);" 

public string IP_Connection(string IP_Address)
        {
            //Port and IP Data for Socket Client
            var IP = IPAddress.Parse(IP_Address);
            int port = 8888;

            var udpClient = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
            var sendEndPoint = new IPEndPoint(IP, port);
            var receiveEndPoint = new IPEndPoint(IP, port);
            var clientReturn = new UdpClient(port);

            //int.TryParse(inputVal, out inputInt);
            int.TryParse("1", out int inputInt);

            // Sends a message to the host to which you have connected.
            byte[] sendBytes = Encoding.ASCII.GetBytes(inputInt.ToString());

            udpClient.SendTo(sendBytes, sendEndPoint);
            string returnData = string.Empty;

            // Blocks until a message returns on this socket from a remote host.
            byte[] receiveBytes = clientReturn.Receive(ref receiveEndPoint);
            returnData = Encoding.ASCII.GetString(receiveBytes);

            udpClient.Close();
            clientReturn.Close();
            return returnData;
        }
