gsm900 programming problem....

[GoogleCodeExporter]

Please i need help i m doing my final year project...... what i want is when 
send sms "On" led should turn on and when i send sms "Off" led should turn off 
but when i send sms "Off" PIR sensor should start work..... but i dont know its 
not working here is my code please anyone can help meee

#include "SIM900.h"
#include <SoftwareSerial.h>
//#include "inetGSM.h"
#include "sms.h"
SMSGSM sms;
int numdata;
boolean started=false;
char smsbuffer[160];
char n[20];
int ledPin = 13; // led connected to control pin 13
int PIRSensor = 2; // the PIR sensor will be plugged at digital pin 2
int val=0;
void setup() {
pinMode(ledPin, OUTPUT); // declare the ledPin as as OUTPUT
pinMode(PIRSensor, INPUT); // declare the PIRSensor as as OUTPUT
Serial.begin(9600); // use the serial port
  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 PIRON(){

if(digitalRead(PIRSensor==HIGH)){   // read the input pin
  digitalWrite(ledPin, HIGH);      // sets the LED to the button's value
  delay(1000);    
digitalWrite(ledPin, LOW);   // delay in milisecond. 3000 = 3 second
  }

}

void loop() {
   if(started){
    //Read if there are messages on SIM card and print them.
    if(gsm.readSMS(smsbuffer, 160, "On", 20))
    {
       digitalWrite(ledPin, HIGH);
      Serial.println(n);
      Serial.println(smsbuffer);

    }
     if(gsm.readSMS(smsbuffer, 160, "Off", 20))
    {

  digitalWrite(ledPin, LOW);

       PIRON();
 Serial.println(n);
      Serial.println(smsbuffer);

    }
    delay(1000);

  }

}

look how readSMS() works...
readSMS(char* msg, int msglength, char* number, int nlength)

the third parameter is number not string_expected

You have to compare the message saved from readSMS, with 
if(strcmp(msg,"On"))
   LED ON
else if(strcmp(msg,"Off")
   LED OFF
check the return of strcmp.
However for this kind of request is better if you use the Arduino's forum (that 
sometimes I check and answer).

The issue are strictly only for library's problem.
