Interface

Usage

Making a call

[code]

#include <SoftwareSerial.h>

SoftwareSerial mySerial(7, 8);

void setup()

{

mySerial.begin(19200);               // the GPRS baud rate  

Serial.begin(19200);               // the GPRS baud rate  

delay(2000);

mySerial.println("ATDxxxxxxxxx;"); // xxxxxxxxx is the number you want to dial. 

if(mySerial.available())

Serial.print((unsigned char)mySerial.read());

delay(10000);

delay(10000);

mySerial.println("ATH"); //End the call.

if(mySerial.available())

Serial.print((unsigned char)mySerial.read());

}

void loop()

{

//Do nothing

}
