“At this point I don’t think I CAN-Bus”. Now I’ve got a CAN stream but while making the DBC mapping the content sniffed from the BMS is different from what I expected and then it should be, but why???
Big thanks to Mischa (Garage71) for solving the CAN-BUS mystery! Solution: press write button in BMS software twice. First run does not always write everything correctly so CAN message content can become a mix of previous and new settings. The good news: easy fix and now know what to do and it was not caused by my lack of understanding.
