Hello everybody,

I'm trying to make a connection between my mobile and my pc.
Im using J2me midp 2.0 to create my code.
The jar of my mobile wants to make a connection to the bluetoothaddress of my pc.
My mobilecode is based on a MIDlet.
But everytime the connection fails. Could someone give me some tips and look to my code.

package bt;

import hello.AlertMsg;
import java.io.IOException;
import javax.bluetooth.RemoteDevice;
import javax.microedition.io.Connector;
import javax.microedition.io.StreamConnection;

/**

 */
public class DeviceConnection {

    private StreamConnection con = null;
    private String devAddress = null;
    private int port = 0;

    public DeviceConnection(String devAddress, int port) {
        this.devAddress = devAddress;
        this.port = port;
        
    }

    public boolean connect() {
        String connectionURL = "btspp://" + devAddress + ":" + port + ";authenticate=false;encrypt=false;master=false;";
        try {
            con = (StreamConnection) Connector.open(connectionURL);
            
            return true;
        } catch (IOException ex) {
            ex.printStackTrace();
        }
        return false;
    }

    public boolean disconnect() {
        try {
            if (con != null) {
                con.close();
            }
            return true;
        } catch (IOException ex) {
            ex.printStackTrace();
        }
        return false;
    }

    public boolean isConnected() {
        if (con != null) {
            return true;
        }
        return false;
    }

    public StreamConnection getConnection() {
        return con;
    }
}
package bt;

        } catch (BluetoothStateException ex) {
            ex.printStackTrace();
        }
    }
