I'm using Java ME and Java Wireless Development Kit for my work. In Addition to that, one needs some Java - Plugins. I'm testing my programs on my mobile phone.

I've never used the JSR-82 API only read about it briefly, so I can't really help on that end. I should maybe have a look. Is there a simple way to get the API onto my PCs or PDAs?

JSR82 <> InTheHand

hello,

I'm working on a connection between JSR82 ( Java on a mobile phone) and PC ( C# ( inthehand) ).

The PC works as a server:

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

   public static Guid TEXTSERVICE = new Guid("12100000000000000000000000000121");
        private Thread thread;
        private bool run = true;
        private BluetoothListener btl;
        private ServiceRecordBuilder SvcBuilder;

        public Form1()
        {
            InitializeComponent();
            if (!BluetoothRadio.IsSupported)
            {
                MessageBox.Show( "No Bluetooth Adapter found!!!");
            }
            else
            {
                if (BluetoothRadio.PrimaryRadio.Mode == RadioMode.PowerOff)
                    BluetoothRadio.PrimaryRadio.Mode = RadioMode.Discoverable;
                // Create and start a thread, listening for an incoming text message
                thread = new Thread(new ThreadStart(runThread));
                thread.Start();
            }
        }

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

private void runThread()
        {
            try
            {
                run = true;
                SvcBuilder = new ServiceRecordBuilder();
                SvcBuilder.AddServiceClass(BluetoothService.RFCommProtocol);
                SvcBuilder.ServiceName = "MyService";

                ServiceRecord record = SvcBuilder.ServiceRecord;

                btl = new BluetoothListener(TEXTSERVICE, record);
                btl.Start();
                while (run)
                {
                    BluetoothClient btc = btl.AcceptBluetoothClient();
                    StreamReader sr = new StreamReader(btc.GetStream());
                    // Create a delegate for setting the text on the main thread
                    this.Invoke((MethodInvoker)delegate
                    {
                        MessageBox.Show("Message received: ");
                    });
                    sr.Close();

                }
            }
            // If the thread gets aborted, an exception is thrown
            catch { }
        }
    }
}

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

Now I'm able fo find the service ( My Service) on mobile Phone(Java) side , but don't know what I've got to do for sending a message to the server and get one back. In a lot of examples work with a objectnotifier by using RFcomm, but inthehand don't have them, or? Or is there anothersolution for sending messages over bluetooth between C# and Java on a mobile phone?

It would be nice, if someone could help me. I wasted the whole last day for this problem.
