What is your device?

I wrote an application for a Dell Axim that sends serial data over
bluetooth. I think this type of communication is called RFCOMM. It turns out
if you open up com7: on an Axim, it will prompt you to select a bluetooth
device and then you use WriteFile and ReadFile like any regular serial
applicaiton.

m_hComm = CreateFile(_T("com7:"), //Bluetooth is com7 on Dell Axim
       GENERIC_READ | GENERIC_WRITE, // Open for Read-Write
            0, // COM port cannot be shared
            NULL, // Always NULL for Windows CE
            OPEN_EXISTING, // For communication resource
            0, // Non-overlapped operation only
            NULL); // Always NULL for Windows CE

The thing I don't know how to do (and I'd love to know more detail) is how
to open an RFCOMM connection to a device without having to open up the
Bluetooth Manager and request the user to select the device. If I know the
Bluetooth Address of the device I want to connect to, how can I simply
connect directly to it (perhaps by some bluetooth API call before the
CreateFile???

Hope this helps get you started.

Hi All,

I need to make an application that send and receive data to/from another
PocketPC, using serial ports, does anyone have an sample application that
shows how using bluetooth technology? or how to use the serial COM
communications?

Thanks,
