hye everybody.. im new in Arduino.. i want to make a program which can print value of AT+COPS? as a sms body? Answered

 yes. my hardware are working and i can get the comms to the phone (just work when i send simple message such as "Hello") but i cannot get the available network as the message to send via phone.
im using Arduino Duemilanove. what do you mean by interface?

How does the phone connect to the Arduino. The connection is called an interface.

So you can send AT commands to the phone  ?

Your code sends "AT +COPS" and should then wait and READ the reply from the phone. Your code has no read command

 is it something like this?

void setup()
{
  pinMode(led, OUTPUT);
  pinMode(onModulePin, OUTPUT);
  Serial.begin(115200;
  Serial.println("AT+CMGF=1");
}

void sms()
{
  Serial.println("AT+COPS?");
  if (Serial.available())
  {
     msg = Serial.read();
  }
}
void loop()
{
  while (count < timesToSend)
  {
     delay(1000);
     Serial.print("AT+CMGS=")
     Serial.print(34,BYTE);
     Serial.print("**********");      // where ********** is the phone number
     Serial.println(34,BYTE);
     Serial.print(msg);                // the sms body that will send message of the                                                       // available network
     Serial.println(0x1A,BYTE);

     count++;
}
if (count == timesToSend)
{
   Serial.println("AT+PSCPOF");
   count++;
}
}

What HARDWARE are you using to talk to the phone ? Are you tying up the serial port on the Arduino, or have we got something we can use as a debug port ? 

Can you talk to the phone at all ? 

I would want to see the message from the phone after
{
  Serial.println("AT+COPS?");
  if (Serial.available())
  {
     msg = Serial.read();
  }

- im using Sagem Communication MODULE Hilo (GSM Module).

-i already can make a missed call and send a simple message to the phone.

- the above coding maybe not working because i got nothing message from the phone..

What does the manual say about the at+cops command ? There are only approximate standards for the AT commands.

 can you help me to correct the coding if there are any errors..
the above coding actually will send an empty message..
thanks a lot for the help

 and im using Windows 7
