httpGET not returning numdata or savind output on results variable.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. On Arduino 1.0.1, open the Library_Client example the is distributed with 
the package.
2. Configure the service provider GPRS details.
3. Upload the sketch to Arduino Uno and watch the serial monitor.

What is the expected output? What do you see instead?
It is expected that,m when the "numdata=inet.httpGET("www.google.com", 80, "/", 
msg, 50);" is executed, the variable "numdata" is filled with the number of 
bytes transfered and the "msg" array with the output of the SIM900 module.
Instead, both variables are not being updated, but I can confirm that the 
SIM900 is returning data if I watch the software serial output.

What version of the product are you using? On what operating system?
Library v304
Arduino 1.0.1
Arduino Uno
Ubuntu 12.10

I got the sema problem too. In rare cases connects and gets an IP, many others 
do not, but whether they connect or not, never gets numdata or msg.

suggestions?

CODE:
#include "SIM900.h"
#include <SoftwareSerial.h>
#include "inetGSM.h"

InetGSM inet;              

char msg[200];
int numdata;
char inSerial[50];
int i=0;
boolean started=false;

void setup()
{
  Serial.begin(9600);
  Serial.println("GSM Shield testing.");
  if (gsm.begin(2400)){
    Serial.println("\nstatus=READY");
    started=true; 
  }
  else Serial.println("\nstatus=IDLE");

  if(started){
    if (inet.attachGPRS("claro.com.br","claro", "claro"))
      Serial.println("status=ATTACHED");
    else Serial.println("status=ERROR");
    delay(1000);

    gsm.SimpleWriteln("AT+CIFSR");
    delay(5000);
    gsm.WhileSimpleRead();
    numdata=inet.httpGET("it.wikipedia.org", 80, "/", msg, 200);
    Serial.println("\nNumero di byte ricevuti:");
    Serial.println(numdata); 
    Serial.println("\nData recived:");
    Serial.println(msg);
  }
};
void loop()
{
}

OUTPUT:

GSM Shield testing.

status=READY
status=ATTACHED

10.79.196.158

Numero di byte ricevuti:
200

Data recived:

There is no Data recived....

[GoogleCodeExporter]

here i  am getting the data received but no in variable msg. if i remove this 
part still will write the data received:

Serial.println("\nNumero di byte ricevuti:");
    Serial.println(numdata); 
    Serial.println("\nData recived:");
    Serial.println(msg);

this is because in SimpleRead is writing this. anyway to get this in msg to be 
able to get this in variable and do whatever i need to do with this?

Thanks

You need to modify the length for the internal communication buffer in the 
GSM.h library!!

#define COMM_BUF_LEN        768
