// Product name: GPS/GPRS/GSM Module V3.0
// # Product SKU : TEL0051
// # Version     : 0.1

// # Description:
// # The sketch for driving the gsm mode via the Arduino board

// # Steps:
// #        1. Turn the S1 switch to the Prog(right side)
// #        2. Turn the S2 switch to the Arduino side(left side)
// #        3. Set the UART select switch to middle one.
// #        4. Upload the sketch to the Arduino board
// #        5. Turn the S1 switch to the comm(left side)
// #        6. RST the board

byte gsmDriverPin[3] = {
  3,4,5};//The default digital driver pins for the GSM and GPS mode
//If you want to change the digital driver pins
//or you have a conflict with D3~D5 on Arduino board,
//you can remove the J10~J12 jumpers to reconnect other driver pins for the module!
void setup()
{
  //Init the driver pins for GSM function
  for(int i = 0 ; i < 3; i  ){
    pinMode(gsmDriverPin[i],OUTPUT);
  }
  digitalWrite(5,HIGH);//Output GSM Timing
  delay(1500);
  digitalWrite(5,LOW);
  digitalWrite(3,LOW);//Enable the GSM mode
  digitalWrite(4,HIGH);//Disable the GPS mode
  delay(2000);
  Serial.begin(9600); //set the baud rate
  delay(5000);//call ready
  delay(5000);
  delay(5000);
}

void loop()
{
  Serial.println("AT"); //Send AT command
  delay(2000);
  Serial.println("AT");
  delay(2000);
  //Send message
  Serial.println("AT CMGF=1");
  delay(1000);
  Serial.println("AT CMGS=\"15800449871\"");//Change the receiver phone number
  delay(1000);
  Serial.print("HELLO");//the message you want to send
  delay(1000);
  Serial.write(26);
  while(1);
}

You can see:

After several seconds, the receiver will get a message from this shield

// Product name: GPS/GPRS/GSM Module V3.0
// # Product SKU : TEL0051

// # Description:
// # The sketch for controling the GSM/GPRS/GPS module via SMS.
// # Steps:
// #        1. Turn the S1 switch to the Prog(right side)
// #        2. Turn the S2 switch to the USB side(left side)
// #        3. Set the UART select switch to middle one.
// #        4. Upload the sketch to the Arduino board(Make sure turn off other Serial monitor )
// #        5. Turn the S1 switch to the comm(left side)
// #        6. Turn the S2 switch to the Arduino(right side)
// #        7. RST the board until the START led is on(make sure you have >6V power supply)
// #        8. Plug the long side of LED into pin 13 and short side into GND
// #        9. Start sending "LH" and "LL" to your board to turn LED on and off.

 *  created:    2013-11-14
 *  by:     Grey
 *  Version:    0.3
 *  Attention: if you send the wrong SMS command to the module, just need to press RST.
 *  This version can't watch the module status via the serial monitor, it only display the Arduino command.
 *  If you want to watch the status,use the SoftwareSerial or the board with another serial port plese.

        delay(500);
      }
    }
  }
}

When you send the SMS "LH" to the module, it WILL turn led on; when you send the SMS "LL", it will be turned off.

How to drive the GPS Mode via Arduino board

• S1 - Comm
• S2 - Arduino
• S3 - UART ( Middle)

Sample code could be found here.

Project Sharing

This code will send GPS information to your phone via SMS. As the picture at right hand.

1. Please download the library.
2. Fill your phone number into the code.
3. Upload the sketch to your Arduino board, after about 5-10 minutes according to your GPS signal intensity.
