Hi,

have anyone gets readind the response of an http request with this modeule ?

I got to send information more or less every 10 seconds. But when I try to get the response of the http the socket closes before i got the data,

This is working ok:

  sprintf(cTemHum,"fTemper=%s&fHumita=%s HTTP/1.1",cTemper,cHumita);
  Serial.print("cTemHum:");
  Serial.println(String(cTemHum));
  
  String request="GET /arduino/guardaTemHum.php?tTipTem=Celsius&"+String(cTemHum); //+"&fHumita="+String(cHumita);
  
  // we're now connected and can send HTTP packets!
  int packetLength = 26+host.length()+request.length()+useragent.length(); // 26 is size of the non-variable parts of the packet, see SIZE comments below
  
  Serial.println("HTTP packet"); //Serial.println(String(packetLength));
  cell.print("AT+SDATATSEND=1,"+String(packetLength)+"\r");
  waitFor('>'); // wait for GSM module to tell us it's ready to recieve the packet
  cell.print(request+"\r\n"); // SIZE: 2
  cell.print("Host: "+host+"\r\n"); // SIZE: 8
  cell.print("User-Agent: "+useragent+"\r\n\r\n"); // SIZE: 16
  cell.write(26); // ctrl+z character: send the packet
  delay(200);
  waitTil("OK");  if (GPRS_Error) return ;
  
  sockAllSend=false;
  sendATCommand("AT+SDATASTATUS=1"); if (GPRS_Error) return ;
  delay(500);
  
  nNumIte=1;
  while (!sockAllSend && sockStatusReady && nNumIte++<30)
  {
     sendATCommand("AT+SDATASTATUS=1"); if (GPRS_Error) return ;
//     delay(500);
  } 
  if (nNumIte>=30) { GPRS_Error=true; return; }
  
    sendATCommand("AT+SDATASTATUS=0"); if (GPRS_Error) return ;
 
  sendATCommand("AT+SDATASTART=1,0"); if (GPRS_Error) return ;
  
  sendATCommand("AT+CGACT=0,1"); if (GPRS_Error) return ;
  delay(1000);
}

buy when I try to read: can’t get it !

  nNumIte=1;
  waitTil("+STCPD:1");  if (GPRS_Error) return ;
  sendATCommand("AT+SDATAREAD=1"); if (GPRS_Error) return ;

CME ERROR: 21 Invalid index

STCPC:1 , comes before READ data !!!

HELP PLEASE !!

Thank’s
