I am creating a driver in KMDF mode. I need to constantly read data (loop) from a serial COM port (that is, a device that connects via bluetooth and constantly sends data while connected).
Search and find these informations:
1) Use ZwReadFile. I was able to read data from the serial COM port, but I don't know how to make it read constantly. I thought of a solution using Timer, but I think there is another alternative that the WDK offers.
2) Use WDFIOTARGET. In fact, this was suggested to me at the Microsoft Q&A. But, I looked for how to use and I saw what they use in many examples. None of them understood how to use it, if you know a simple example it would be very helpful.
Either by ZwReadFile or WDFIOTARGET, any information would be very helpful.
