As far as I know OBDLink brand and scan tool (IC manufacturer) are under the same ownership/direct partnership. the STN2100 is just the newer version of the chip.
I would suspect one of the OBDLink products uses it, that’s past what I looked into. may be best to contact them and ask if it isn’t in their documentation.
But don’t mind me, I’m a total novice and hack at this stuff, I have some defined things I want to do and still building the path to get them done.
all that research on OBDLink/Scan Tool is what lead me to the A0 since it does everything the OBDlink cable does but more and easier (since I don’t live and dream in c++ or other code/programing/networking environments) and the hardware can be repurposed to implement everything it was used to figure out since I do muddle around in Arduino.
it took just a few minutes to get Saavycan to record traffic with the A0, which took a bit more to do with the OBDlink cable displaying the CAN traffic in PuTTY, I couldn’t figure out how to get the obdlink cable to work with saavycan or any other CAN divide and conquer software (that was windows based) that didn’t cost more than the A0.
maybe your skillset is great enough in this are that all you need is the OBDLink hardware ST command set to bridge CAN to your preferred environment which would rock and I’m envious of, I have enough trouble just getting software and hardware to acknowledge each other’s existence, let alone play nice to each other.
