Hi. I am new in GSM shield.
Using icomsat 1.1 I successfully connected my Arduino Uno to pin 4 and pin 5 with library BETA_GSM_GPRS_GPS_IDE100_v304..
For some reason the code authorization doesn't really do anything even though I have 1 phone-book save in the SIMCARD the other SMS that is not save in the phone book will be print also..
#include "SIM900.h"
#include "sms.h"
#include <SoftwareSerial.h>
SMSGSM sms;
boolean started=false;
char phone_num[20]; // array for the phone number string
char sms_text[100]; // array for the SMS text string
void setup()
{
//Serial connection.
Serial.begin(9600);
Serial.println("GSM Shield testing.");
//Start configuration of shield with baudrate.
//For http uses is raccomanded to use 4800 or slower.
if (gsm.begin(2400)){
Serial.println("\nstatus=READY");
started=true;
}
else Serial.println("\nstatus=IDLE");
if(started){
//Enable this two lines if you want to send an SMS.
//if (sms.SendSMS("3471234567", "Arduino SMS"))
//Serial.println("\nSMS sent OK");
}
};
void loop() {
char position = sms.IsSMSPresent(SMS_UNREAD);
char position2 = sms.IsSMSPresent(SMS_READ);
if (position) {
if(sms.GetAuthorizedSMS(position, phone_num, sms_text, 100, 1, 10))
{
Serial.println(phone_num);
Serial.println(sms_text);
}
else {
sms.DeleteSMS(1);
Serial.println("deleted");
}
}
if (position2) {
sms.DeleteSMS(position2);
}
delay (100);
};
What I am really wanted to do is print only the SMS coming from my phonebook. Sorry for my bad English. I hope you'll answer this soon. I really need it.
