Pocket PC Networking, MS / widcomm bluetooth programming

Hi I'm rather new to Bluetooth programming.

Is there a way to make one program using VC++ CE 4.2 that works both with
Widcomm and Microsoft Bluetooth stack? Does programming with OBEX or Serial
Connectivity works?

I couldn't find a simple up-to-date answer of this issue on the internet.

Please help

Microsoft and Widcomm have completely different SDKs. If you are creating
a simple enough application you might be able to get away with just using
virtual COM ports (Serial Port Profile). Virtual COM ports use standard
Windows CE APIs which wrap Microsoft and Widcomm BT stacks.

I hope this helps.

Hi Greg,

Can you point us at more info on using "virtual com ports (Serial Port
Profile)" ?

There is a lot of info on MSDN. The following page actually shows you how
to register the virtual COM port with BT (most devices have some UI to do
this). So you probably won't need to call RegisterDevice as described here:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wcecomm5/ht
ml/wce50concomportemulationfacility.asp

Here are some links to the general purpose APIs for using COM ports (this
will be applicable for both MS & Widcomm stacks):

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wceobjst/ht
ml/cerefCreateFile.asp

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wceobjst/ht
ml/cerefreadfile.asp

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wceobjst/ht
ml/cerefwritefile.asp

If you install Windows CE Platform Builder (evaluation edition) you can
find some samples here:

public\common\oak\drivers\bluetooth\sample
public\common\sdk\samples\bluetooth

Good luck!
