PC application with bluetooth

[urip]

Hello everybody,

I'm trying to develop a PC application with a Bluetooth connection using a USB dongle.
The application is supposed to search for devices in range, choose one of them, and then send him a file...


I have searched the net looking for a way to do it, but didn't find one.
Is it possible to develop such application? If so, how can I do it? What should I look for? Is Java the ideal language for this application? (I don't care to use C# or C++ instead...)



Thanks....

That's an interesting question. I haven't program anything like that but I found some information for you (and for my own enjoyment ). Apparently Java provides an API to interact with bluetooth devices on the package javax.bluetooth. You can find the information here: Using the Java APIs for Bluetooth Wireless Technology

How didn't I find this one? Seems like a very good place to start from...
Thank you very much

Well, after a lot of work, using bluecove (jsr-82), I've succeeded in making a device discovery search, select a mobile phone, search for services and make a connection attempt..
So far so good, but when I try to connect the mobile, my cell demands a passkey (in order to pair itself to the PC).
So I have two questions (I've listed some code in the bottom):

1. Is it possible to send a message without the passkey and the pairing? (only by clicking yes/no to accept the connection by the cell) For instance, when I send a file from one mobile phone to another, it doesn't request a passkey, only an approval from the mobile user. How is it done?

2. If it's not possible to connect without the passkey, how do I enter the pairing passkey back in the PC?

This is how I'm trying to initialize the connection:

    ...
    //after finding the remote device...
    int[] attrSet = new int[] { 0x0100};
    UUID uuidSet[] = new UUID[] { new UUID(0x1106) };
    int bl = _discoveryAgent.searchServices(attrSet, uuidSet, devices[i], this);
    ...
 
    public void serviceSearchCompleted(int transID, int respCode)
    {
            if(respCode == SERVICE_SEARCH_COMPLETED)
            {
                try
                {
                    //servRecord holds the found ServiceRecord
                    String connectionUrl = servRecord[0].getConnectionURL(ServiceRecord.NOAUTHENTICATE_NOENCRYPT, false);
                    StreamConnection streamConnector = (StreamConnection) Connector.open(connectionUrl);
                    String msg = "Success.";
                    OutputStream os = streamConnector.openOutputStream();
                    os.write(msg.getBytes());
                    streamConnector.close();
                }
                catch(Exception exc)
                {
                    System.out.println("Error occured: " + exc);
                }
            }
    }

I hope I explained the code enough
Thanks
