In the car with ignition on, the listen-only probe found 500 kbps (2673 frames in 3 s, zero RX errors; nothing at other rates). The OBD port isn't gatewayed: 27 periodic IDs, ~893 frames/s. A udev rule now starts can-up@can_pcan on boot and hot-plug with 500k and listen-only, to be dropped when obd-poller becomes the single writer. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
