Error in decoding J1939 frames

[acode-x]

Hi,

I am using a demo J1939 DBC file from CSSElectronics.
Here is the example I am testing dbcppp with

BO_ 2364540158 EEC1: 8 Vector__XXX

> cansend vcan0 0CF00400#FFFFFF6813FFFFFF

I notice the DBC ID is 32bits (2364540158) and CAN ID is 29bits (217056256), and due to same, the example from the README.md fails to find a match.

        receive_frame_data(&frame);
        auto iter = messages.find(frame.can_id);
        if (iter != messages.end())

---

Please note from above image, CAN ID is different from DBC ID for the same PGN.

I face the similar behaviours in cantools.

Could you suggest me how to handle the above. Having a separate function to convert CAN ID to DBC ID is 1 way I could think of, but I am not sure how to do that.
Would like to know your thoughts.

Thanks in advance.

Some times the source address (last 8bits) is also different but PGN is same. Not sure if checking only the PGN is right approach.
