Thread: Stop receiving packet from motes

Hi everybody,

I have a java code that read packets from telosb motes.

here my main function

 
public static void main(String[] args) throws Exception {
 
  String source = null;
    if (args.length == 2) {
 
      if (!args[0].equals("-comm")) {
	       usage();
	       System.exit(1);
      }
 
      source = args[1];
    }
    else if (args.length != 0) {
      usage();
      System.exit(1);
    }
 
  PhoenixSource phoenix;
 
  if (source == null) {
      phoenix = BuildSource.makePhoenix(PrintStreamMessenger.err);
   }
   else {
     phoenix = BuildSource.makePhoenix(source, PrintStreamMessenger.err);
   }
 
   MoteIF mif = new MoteIF(phoenix); 
 
   Forwarder serial = new Forwarder(mif);
 
 
   }

and here the Forwarder constructor

public Forwarder(MoteIF moteIF) {
 
            this.moteIF = moteIF;
            this.moteIF.registerListener(new MyMessageMsg(), this);//  Register a listener for given messages type.
 
  }

and I have function that invoked when new packet arrive

public void messageReceived(int to, Message message) {
    MyMessageMsg msg = (MyMessageMsg)message;
 
 
 
 
 
    if(msg.get_area() != 7 ){ 
        System.out.println("-----Recive  New Message -------" ); 
 
 
    }
 
 
 
  }

my question is : how I can stop packets receiving after receiving 200 packets ?

I read from here MoteIF

That I can use "deregisterListener" method to do that

but I don't know how to do that to stop receiving packets


please, help me

I don't know for sure, but I'll hazard a guess: Count the packets as they arrive in the 'messageReceived' method, and check the count at the end of the 'messageReceived' method. If the count has reached 200, call this.moteIF.deRregisterListener().

Thank you so much

I did the same but I got exceptions.

the method 'messageReceived' is invoked automatically when one packet arrive

I couldn't stop this automatic calling with this way and I searched over web but I can't find any similar example

Any help please

Sadly, I'm not clairvoyant, so unless you post the code that shows exactly what you did and full text of the exception messages and stack traces you got, I can't help.

The problem is solved.
