#69593 Hello guys!!!
what is the best way to send and receive information from esp8266 in C# and showing it???
i used some codes but they didn't work:(
on the ESP:
Code: Select allvoid loop() {
  WiFiClient client = server.available();
  if (!client) {
    return;
  }
  while (!client.available()) {
    delay(1);
  }
  String request = client.readStringUntil('\r');
  Serial.println(request);
  client.flush();

  client.println(Data);

}

Wifi Connection is valid and the ip address is known.this code waits for a request and shows the request on SerialTerminal and send the "Data" to client.


and the PC side using System.Net.WebClient:
Code: Select allWebClient wc = new WebClient();
byte[] Data = wc.DownloadData("http://192.168.1.100/This_is_a_test");
File.WriteAllBytes(@"D:\A.txt", Data);


the problem is that when you request on a web explorer(Like mozila or anything) on a PC is in the same LAN it works great. it shows the Data and Serial shows the request that you entered on web explorer.

but the C# codes give me an error:
The server committed a protocol violation. Section=ResponseStatusLine

however the request that i entered in the C# codes ("This_is_a_test") is shown in the SerialTerminal.


is there anyway to communicate between esp and a C# application without these errors??? :?: :?: :?:
