i bought this shield.
My project is to make a tracker using the gps and upload the data to server
this is the code im using
int8_t answer;
int onModulePin= 2;
char gps_data[100];
int counter;
char aux_str[50];
char server[ ]="***.***.net";
char port[ ]="80";
void setup(){
pinMode(onModulePin, OUTPUT);
Serial.begin(115200);
Serial.println("Starting...");
power_on();
delay(5000);
// starts GPS session in stand alone mode
answer = sendATcommand("AT+CGPS=1,1","OK",1000);
if (answer == 0)
{
Serial.println("Error starting the GPS");
Serial.println("The code stucks here!!");
while(1);
}
//sendATcommand("AT+CPIN=5512", "OK", 2000);
//delay(3000);
while( (sendATcommand("AT+CREG?", "+CREG: 0,1", 500) ||
sendATcommand("AT+CREG?", "+CREG: 0,5", 500)) == 0 );
// sets APN, user name and password
sendATcommand("AT+CGSOCKCONT=1,\"\",\"jawalnet.com.sa\"", "OK", 2000);
sendATcommand("AT+CSOCKAUTH=1,1,\"\",\"\"", "OK", 2000);
}
void loop(){
answer = sendATcommand("AT+CGPSINFO","+CGPSINFO:",1000); // request info from GPS
if (answer == 1)
{
counter = 0;
do{
while(Serial.available() == 0);
gps_data[counter] = Serial.read();
counter++;
}
while(gps_data[counter - 1] != '\r');
gps_data[counter] = '\0';
if(gps_data[0] == ',')
{
Serial.println("No GPS data available");
}
else
{
Serial.print("GPS data:");
Serial.println(gps_data);
Serial.println("");
sprintf(aux_str, "AT+NETOPEN=\"TCP\",%s", port);
answer = sendATcommand(aux_str, "Network opened", 20000);
if (answer == 1)
{

sprintf(aux_str, "AT+TCPCONNECT=\"%s\",%s", server, port);

}
}
}
else
{
Serial.println("Error");
}
delay(5000);
}
void power_on(){
uint8_t answer=0;
// checks if the module is started
answer = sendATcommand("AT", "OK", 2000);
if (answer == 0)
{
// power on pulse
digitalWrite(onModulePin,HIGH);

// check if the desired answer is in the response of the module

// Waits for the asnwer with time out

}
i don't know why its not connecting to the server !
this is on serial monitor
AT+NETOPEN="TCP",80
Network opened
AT+TCPCONNECT="malik.basalamah.net",80
Connect ok
Socket opened
AT+TCPWRITE=55
