hi everyone,
how can i blink an LED when the GSM shield is initialised, the shield has an inbuild one but i want to add an external one because the shield will be enclose and i need and external 1 as guide.
#include <GSM.h>
// PIN Number for the SIM
#define PINNUMBER ""
// initialize the library instances
GSM gsmAccess;
GSM_SMS sms;
// Array to hold the number a SMS is retreived from
char senderNumber[20];
void setup()
{
pinMode(5, OUTPUT);
// initialize serial communications and wait for port to open:
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for Leonardo only
}
Serial.println("SMS Messages Receiver");
// connection state
boolean notConnected = true;
// Start GSM connection
while (notConnected)
{
if (gsmAccess.begin(PINNUMBER) == GSM_READY)
{
notConnected = false;
digitalWrite(5,HIGH);
delay(64);
digitalWrite(5,LOW);
delay(3000);
}
else
{
Serial.println("Not connected");
delay(1000);
}
}
Serial.println("GSM initialized");
Serial.println("Waiting for messages");
}
void loop()
{
char c;
// If there are any SMSs available()
if (sms.available())
{
Serial.println("Message received from:");
// Get remote number
sms.remoteNumber(senderNumber, 20);
Serial.println(senderNumber);
// An example of message disposal
// Any messages starting with # should be discarded
if (sms.peek() == '#')
{
Serial.println("Discarded SMS");
sms.flush();
}
// Read message bytes and print them
while (c = sms.read())
{
Serial.print(c);
}
Serial.println("\nEND OF MESSAGE");
// Delete message from modem memory
sms.flush();
Serial.println("MESSAGE DELETED");
}
delay(1000);
}
