OBD2
« on: September 22, 2018, 11:15:36 pm »
I bought 2 USB dongles but none of them acknowledged by Window 10 computer. I installed provided software on one USB and it work. I want to develop my own software, but first step is communication between ODB2 and my computer. For some unknown reasons I am unable to communicate. I am using Windows 10.

Any help will be very much appreciated.  8)

If the device vendor or another source doesn't provide documentation for how to communicate with the device in your own programs, you might need to reverse-engineer the protocols by capturing data on the bus.

Windows Device Manager will show what driver Windows has assigned to the device.

Jan, I was recently in need of a better one that I have.
I found many of those links no longer work or point to devices no longer supported/manufactured.
