PC application with bluetooth

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. :icon_sad:
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.... :icon_wink:

Personally, use C++.

Thank you, your link was very helpful.
But now I have another question:

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.

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

Re: PC application with bluetooth

Can be done with JSR with J2me

Re: PC application with bluetooth

In this case, I'm talking about J2SE only, due to the fact I'm programming this application for my computer...

I know this attributes determine the type of service we are looking for:

    int[] attrSet = new int[] { 0x0100};

    UUID uuidSet[] = new UUID[] { new UUID(0x1106) };

Those variables are later on passed to the discovery agent:

_discoveryAgent.searchServices(attrSet, uuidSet, devices[i], this);

Maybe there are other properties except 0x0100 and 0x1106 that will do the work? I tried to learn more about those properties but found nothing about it.
