I am interested in starting the implementation for B250E.
The car was designed when Mercedes co-operated with Tesla, so BMS and drive unit should be already well supported. Additionally Smart ED might be very similar to this one.
Is there anyone who have done some experiments with this car? What would be the easiest way to verify that the CAN bus is available in the OBD connector (before buying OVMS)? Generic adapters do not report anything from the car..
