It looks like you're receiving the basic data (Voltage, Current, and SOC) but no other data. Given that, I think it's likely your BMS isn't responding to those other commands, or is responding with all 0s. Maybe it's an older version that doesn't implement those commands. Would you mind sharing a picture of what your BMS looks like. It might also be helpful to define the debug tag in the library so that all the debug info is printed out.
