The error code I am getting when I try this sometimes is 0. The error codes listed are 1, -1, -2, -3 and -4 in the site Ethernet - Arduino Reference. Why am I getting 0?
thanks in advance for any help!
How about posting the code that you are using ?

void StopCall()
{
Serial.println();
Serial.print("Call status - ");
client.stop();
/*Close any connection before a new request is sent to free the socket on the WiFi shield!
* Any GET request, the server generates a response.
* Until the response is read, this connection is open.
* 4 connections at a time is the maximum!
* Hence, close the connection just to be sure, by reading the response.
*/
//client.connect(ip/url, port) - (SUCCESS = 1; TIMED_OUT = -1; INVALID_SERVER = -2; TRUNCATED = - 3; INVALID_RESPONSE = -4;)
int callStatus = client.connect(server, 8085);
switch (callStatus)
{
case 1:Serial.println("Connection established with server!");
//GET request for e-stop
client.println("GET URL HTTP/1.1");
client.println("Host: IP");
client.println("Connection: close");
client.println();
Serial.println("Server response...");
delay(serverResponseDelay);
/*while(client.available()) //Print response
{
char c = client.read();
Serial.print(c);
}
Serial.println();*/
realizeJson();
lastCallTime = millis();
break;
case -1:Serial.println("Timed out. Retrying!");
break;
case -2:Serial.println("Invalid server. Retrying!");
break;
case -3:Serial.println("Truncated response. Retrying!");
break;
case -4:Serial.println("Invalid response. Retrying!");
break;
default:Serial.print("Unknown! - Error Code: ");
Serial.println(callStatus);
break;
}
}
When I print callStatus when the code goes into the default case, I get an output as 0.
I am thinking it is because my WiFi had no signal. I am seeing that behavior when I switched off my WiFi connection. Earlier the connection might have been intermittent. Am I getting this right?
