ESP32RET
FirmwareRead and record CAN traffic with a Macchina A0
ESP32RET turns a Macchina A0 into a CAN interface for SavvyCAN, a desktop tool for examining vehicle messages. It also provides Bluetooth Classic ELM327 emulation, which the author tested with Torque.
You flash the A0 over USB, then plug it into the car's OBD-II port. The project describes itself as work in progress, and LAWICEL support is experimental. Its CAN interface can transmit as well as receive, so a recording setup should begin in listen-only mode.
