Act as server and parse python-can messages about python-udsoncan HOT 6 CLOSED

Hi
You are passing an isotp payload directly to the UDS layer. You are lacking a layer of interpretation. The first byte is meant to be consumed by that isotp (transport layer). You can look at my other project for an implementation of that layer. If you input the whole Can message on one side, you will received the UDS payload on the other

Let me know if I can help, you have some doc reading to do first I believe :)

@pylessard thank you - but which one project you're talking about? :D Can you please point me some example or code line to get familiar with? I think you're talking about python-isotp.

I have 2 projects, the other one is called python-can-isotp. Which implements the isotp protocol as per above comment.
There are plenty of examples in the documentation, start there

@pylessard sorry for asking stupid questions, but as I understand I need to implement custom rxfn and txfn functions in isotp transport layer? Or totally avoid using isotp and implement own wrapper to handle this translation between isotp and uds?

Don't hack it. Isotp headers are not always 1 byte.

You need a custom rxfn/txfn if you have specialized hardware. If you use python-can, the work is already done. See this example : https://udsoncan.readthedocs.io/en/latest/udsoncan/examples.html#using-uds-over-python-can
