WDM to WDF convert question.

NTDEV
1

Dear All,
my university project is bluetooth driver using wdf.
I build the bluetooth protocol which include (obex, rfcomm, l2cap, hci )
the problem that I face which I think in the driver is the driver for some reason will stop of sending or reciving.
I have read some articles around that wdf solve some problem of locks and has default queues for I/O requests.
in fact I m new in driver developmenet, if some one help me to conevrt my driver from wdm to wdf I will be so thankful.
the driver is taken from open source code at this link, www.freebt.net.
regards,

I don’t think anyone is going to port it for you, but before you set out to port from wdm to wdf, you should really triage what the problem(s) you are having and decide if KMDF is really going to help you or not. For instance, why the receiving/sending path actually stopping? A deadlock between 2 diff locks? A missing HCI credit?

Anyways, if you decide that kmdf is going to help you there are porting resources on WHDC, http://www.microsoft.com/whdc/driver/wdf/KMDF.mspx. Look for “Porting from WDM to KMDF” and the associated topics

Um…no ;). Besides what I am sure are a ton of IP issues, I do not have the time and you should learn to bail yourself out of your own problem. Having someone else do it for you is not the right way to learn, is it?
