Topic: Difficulties in editing Receive Voice Call example >.< (Read 4632 times) previous topic - next topic


Hey everyone :)
iv been having problems programming  since im a newbie and after many searches and dead ends iv been  told this is the right place to ask

i wanted to make a simple code to switch on a relay on if the calling number is only my number and if i called again it switches it off so i tried to compare the (numtell) array with a my number but it doesn't work

// Include the GSM library
#include <GSM.h>

// PIN Number
#define PINNUMBER ""

// initialize the library instance
GSM gsmAccess;
GSMVoiceCall vcs;

// Array to hold the number for the incoming call
char numtel[20];           

pinMode(4, OUTPUT);
  digitalWrite(4, LOW);

void setup()
  // initialize serial communications and wait for port to open:
  while (!Serial) {
    ; // wait for serial port to connect. Needed for Leonardo only

  Serial.println("Receive Voice Call");
  // connection state
  boolean notConnected = true;
  // Start GSM shield
  // If your SIM has PIN, pass it as a parameter of begin() in quotes
      notConnected = false;
      Serial.println("Not connected");
  // This makes sure the modem correctly reports incoming events
  Serial.println("Waiting for a call");

void loop()
  // Check the status of the voice call
  switch (vcs.getvoiceCallStatus())
    case IDLE_CALL: // Nothing is happening
    case RECEIVINGCALL: // Yes! Someone is calling us
      Serial.println("RECEIVING CALL");
      // Retrieve the calling number
      vcs.retrieveCallingNumber(numtel, 20);
      if( numtel == +11111111111 ;){
digitalWrite(4, HIGH);
\\and the  rest of the things i want to be done
      // Print the calling number
      // Answer the call, establish the call
    case TALKING:  // In this case the call would be established
      Serial.println("TALKING. Press enter to hang up.");
      Serial.println("Hanging up and waiting for the next call.");     

and some other few questions (other than the main question up there):
1 -how can i make a delay without stopping the arduino (with a small example please)
2 -i notice there is a command called (Break;) what does it mean and how can i use it

and im sorry if im asking too silly questions or asking alot
and thanks in advance :)


No one knows anything??
or am i in the wrong section??


I'm fairly sure that your actual code doesn't have a smiley face in it!

If you read the sticky about how to use the forum and reformat your code as outlined in there then you might get more assistance.
