You can configure some pin to interrupt with INTx interruptions.

This is a example: http://www.avr-tutorials.com/interrupts/avr-external-interrupt-c-programming

See ATMega328 manual for more information.

Hi,

How did you send/receive SMS? Between two shields? With a smartphone to send or to receive?

Please, tell us more details.

hi, can you execute ReceiveSMS example with debug mode??

To actívate debug mode, replace this line:
GSM gsmAccess;
with:
GSM gsmAccess(true);

Jump pin 2 with pin 10.

You can try it. You have to connect TX/RX and POWER_KEY modem pins to the appropiate outputs of Funduino.

Put this code in your Arduino and enter AT commands with Serial Monitor:

#include <SoftwareSerial.h>
#include <string.h>

char incoming_char = 0;
SoftwareSerial cell(2,3);

void setup()
{
  // Initialize serial ports for communication.
  Serial.begin(9600);

  // Reset
  Serial.println("Start Reset");
  pinMode(7, OUTPUT);
  digitalWrite(7, HIGH);
  delay(12000);
  digitalWrite(7, LOW);
  delay(1000);
  Serial.println("End Reset"); 

  cell.begin(9600);

  Serial.println("Enter your AT commands (with CR & NL)...");
}

void loop()
{
  if(cell.available() > 0)
  {
    incoming_char = cell.read();
    if((incoming_char >= ' ') && (incoming_char<='z'))
      Serial.print(incoming_char);
    else
    {
      Serial.print("%");
      Serial.print((int) incoming_char);
      Serial.print("%");
      if(incoming_char == 10)
        Serial.println();
    }
  }

  if(Serial.available() > 0)
  {
    incoming_char = Serial.read();
    cell.print(incoming_char);
  }
}

You can do it with SoftwareSerial library. Modem uses digital pin 2 for RX and digital pin 3 for TX.
53  Products / Arduino GSM Shield / Re: Original Arduino GSM Library - change RX / TX to Hardware Serial on: February 20, 2014, 09:12:21 am
In theory, you can replace all references to SoftwareSerial with Serial class.
54  Products / Arduino GSM Shield / Re: Softserial problem / using uart possible? on: February 20, 2014, 09:04:57 am
If I can remember, Mega has three Serials, Serial1, Serial2 and Serial3. Replace Serial with Serial1, Serial2 or Serial3.

PIR sensors are very sensitive with radio communications, they can give false positives with a simple communication.  Check with your serial monitor if is a problem of sensor or a problem of GSM library when it executed.

Hi,

Search a tutorial for Arduino, GSM Shield doesn't affect if you use others digital o analog pins (D2 and D3 are used by GSM Shield). You can use a servo connected to a PWM output, and manage it rotation in your sketch.

BlueVia SIM only works with other BlueVia SIM for SMS service.

You cannot see how much data have you spent. You can ask this question to your operator.

Now, in BlueVia website you can see the telephone number.

Official Arduino GSM Library was designed for Quectel M10 modem, included in oficial GSM Shield.
