Bluetooth simply emulates a serial port, network interface, keyboard, mouse,
or sound card. You interact with this emulated device the same way you do
with native devices that have the same functionality. None of this requires a
dedicated SDK.
What are you trying to do with it? Just get some data to another computer?
Are the two machines already paired?
If that's the case, you just need to use the bluetooth serial port to do
your bidding. This works just like the other serial ports: the simplest way
is to just open a stream to "COMx:", where x is the serial port that is
assigned to your bluetooth connection. You can also connect your devices
through TCP/IP using the personal network Bluetooth profile. Then your PDA
can exchange data with any PC on your LAN, or even through the Internet.
