Hello!

Please specify where do you send data via retranslator to Wialon  or to other system (from Wialon)
Which TCP protocol do you use?

Re: wialon retrasnlator response

hello! thank for the answer!
i  convert the hex string into binary data with this c# code

string finalBinaryString = String.Join(String.Empty,
                finalHexString.Select(
                    c => Convert.ToString(Convert.ToInt32(c.ToString(), 16), 2).PadLeft(4, '0')
                )
                );

and then i convert the binary data into byte array with this code

int numOfBytes = finalBinaryString.Length / 8;
                byte[] binaryBytes = new byte[numOfBytes];
                for(int i = 0; i < numOfBytes; ++i)
                {
                    binaryBytes[i] = Convert.ToByte(finalBinaryString.Substring(8 * i, 8), 2);
                }

finally i send it via tcp protocol with web socket

IPEndPoint remoteEP = new IPEndPoint(ipAddress, 20163);
 Socket sender = new Socket(ipAddress.AddressFamily, SocketType.Stream, ProtocolType.Tcp); 
  sender.Connect(remoteEP);
int bytesSent = sender.Send(binaryBytes);
