Service Registration question

[asmatic]

Hello

I'm creating a service (serial port) in a Nokia 6600 phone.

When I start the applet that starts the service, I can't see the service if I explore the surrounding devices with my PC and search for services in it.

Using BTbrowser I can see that the service appears to be up.

However the PC cant see it. The problem is that a external device that must connect (a RFID) with the service seems unable to see it neither, maybe because of the same reason.

Here is some code

--------------------------------

import javax.bluetooth.UUID;
import javax.microedition.io.*;
import javax.bluetooth.*;
import java.io.*;
import java.util.Enumeration;
/**

public class GestorBTServer extends GestorBT implements Runnable {

private StreamConnectionNotifier conexiones = null;
private UUID serverUUID = null; //new UUID("102030405060708090A0B0C0D0E0F010", false); just uing this UUID for testing purposes
private String srvName = "";
private RFIDParser parser = null;
private StringBuffer url = null;
private String data = null;

private boolean parar = false;

/**

public GestorBTServer(String name,String uuid,Actualizable a) {
super(a);
this.srvName = name;
this.serverUUID = new UUID(uuid,false);
setVisibilidadOn(); // permitir a otros dispositivos encontrarme si me buscan

this.url = new StringBuffer("btspp://localhost:"); // construimos la Url
this.url.append(this.serverUUID.toString());
this.url.append(";authenticate=true;encrypt=true");
this.url.append(";name=");
this.url.append(this.srvName);
this.parar = false;
}

try {
this.conexiones = (StreamConnectionNotifier) Connector.open(this.url.toString());

//

}
}
--------------------------

//... main midlet code
public RFID()
{
this.BT = new GestorBTServer("Bluetooth Serial Port\n","102030405060708090A0B0C0D0E0F010",this);
this.pantalla = Display.getDisplay(this);
this.mainFrm = new Form("Esperando conexion con RFID");

this.mainFrm.setCommandListener(this);
this.infoAlert = new Alert("Información:","",null,AlertType.INFO);
}

protected void startApp() throws MIDletStateChangeException {
this.pantalla.setCurrent(this.mainFrm);
this.BT.runServer(); // inicia servidor
}
//...
---------------------------------

maybe I'm doing something wrong.

All the attributes that I enable on the service record are to mimic the attributes that i can find on the serial port service of my USB dongle (the RFID connects suscesfully to my PC)

Thank you

Another question:

When I create the service with master=true in the URL the app creates an exception with symbian error code -5. (The operation requested is not supported)

maybe the 6600 can't create services as a master?

thanks
