Has anyone connected a TrackerOne to a vehicle or equipment using the OBD2 interface? I purchased the M8 adapter cable from Particle and an ODB2 connector cable from Amazon. I’m looking for both wiring and firmware examples if available. -Thanks!
The Tracker CAN Application Note uses OBD-II to demonstrate CAN capabilities and includes wiring information for the J1962 cable.

Thank you so much! That’s exactly what I was looking for!
Hi rickkas7, Maybe you can help me. I got the TrackerOne and OBD-2 connected and I’m reading from the OBD-2 port of my vehicle using your sample code from github. However, I’m not getting the RPM data. If I understand correctly, the response should start with the OBD_CAN_REPLY_ID (7e8). Below is an example of what the canInterface.readMsgBufID is reading. I let it run for 15 minutes and never got the 7e8 code. Could it be different on my car? How can I find this info? TIA
