I guess he wants to control something by detecting an incoming call without answering it.

Well here you go:

WaitForCall();
If (ledIsOff()){
    TurnLedOn();
}else{
    TurnLedOff();
}

Just fill in the blanks

Sorry, I forgot to set my phone's autocorrect language to "C" :stuck_out_tongue:

  • Detect the RING mesages from your modem.
  • You need to wait for the second RING - then parse the Caller-ID sentence.
  • Validate the incoming number against your allowed callers.
  • Send 'Hang Up' to the modem (ATH).

Do whatever you want with the knowledge that a 'valid' number called and you hung up on them without answering.
If you don't care who calls - skip steps 2 & 3

this is the code for LED Turn in and OFF LED by using missed Call

#include<SoftwareSerial.h>
SoftwareSerial gsm(2,3);//2 is RX Pin 3 is TX Pin of Arduino Uno
int led = LED_BUILTIN;
char phoneNo[]="91xxxxxxxxxx";//replace xxxxx with your mob no.
int ledState =0;
int oldCon = 0;
int con;

void setup()
{ pinMode(led, OUTPUT);

gsm.begin(9600);
}
void loop()
{
if(gsm.available())
{
con = gsm.find(phoneNo, 12);//function gsm.find() only return '1'or '0'

if(con==1 && oldCon==0)
{
delay(2000);
gsm.println("ATH");

if(ledState==0)
{digitalWrite(led, HIGH);
ledState=1;
}
else
{digitalWrite(led, LOW);
ledState=0;
}

}

oldCon=con;
}

}
