Hi all
Its a while i have been searching net
for some information about supporting Bluetooth
in Delphi application,but i have not found much.
Is there anyone who can help me with that?
I would verry much appreciate that .:)

Bluetooth was designed as a C and C++ API, but you can use the Windows Sockets interface directly to make a Bluetooth application. (People also sell components you can use with Delphi, but they aren't cheap.)

You might want to check out these MSDN articles:
Bluetooth Programming with Windows Sockets
Bluetooth Reference

That's the best I could google with a short attention span. Good luck!
