You can also optionally give ‘re obdii extended …’ for extended frames as well. The RE tool will then treat messages on those IDs as OBDII requests/responses and key appropriately. The keys are O2Q for query, and O2P for reply. The “m1” is mode #1. The final digits (after the “:”) is the PID requested/replied. This should work for both OBDII requests and replies (although only standard mode requests tested so far). At the moment, I’m monitoring frames inbound (can rx) only. We could monitor tx as well, without too much difficulty. Here is what a O2 vehicle module on the box, talking to an external OBDII ECU simulator, looks like: OVMS > re obdii standard 7df 7ef Set OBDII standard ID range 7df-7ef OVMS > vehicle module O2 I (593927) v-obdii: Generic OBDII vehicle module I (593927) events: Signal(power.can1.on) OVMS > re list key records ms last can1/7e8 3 19666 22 37 32 35 32 33 36 37 can1/7e8:O2Pm1:12 6 9833 04 41 0c 3c 13 00 00 00 can1/7e8:O2Pm1:13 5 11800 03 41 0d 5b 00 00 00 00 can1/7e8:O2Pm1:15 2 29500 03 41 0f 41 00 00 00 00 can1/7e8:O2Pm1:47 2 29500 03 41 2f 80 00 00 00 00 can1/7e8:O2Pm1:5 2 29500 03 41 05 40 00 00 00 00 can1/7e8:O2Pm1:70 2 29500 03 41 46 3c 00 00 00 00 can1/7e9:O2Pm1:12 6 9833 04 41 0c 3c 13 00 00 00 can1/7e9:O2Pm1:13 5 11800 03 41 0d 5b 00 00 00 00 can1/7e9:O2Pm1:5 2 29500 03 41 05 40 00 00 00 00 can1/7ea:O2Pm1:13 5 11800 03 41 0d 5b 00 00 00 00 Committed, and pushed.
