can you please point me some online tutorial/manual or some literature that can help me with bluetooth programming ?
I'm a newbie to Windows Mobile programming so any hints or recommendations will be appreciated.
Assuming you are talking about .NETCF development you'll find everything required in this package:-
Including source (C#), sample projects, class documentation. It also closely follows the IrDa classes in .NETCF so should be easy to pickup. It'll work on XP or Windows CE/ Windows Mobile so long as you are using the Microsoft stack (not from a third-party such as Broadcom).
