Hi, for such a use case I've extended scapy a while ago. Maybe you can make use of it: https://scapy.readthedocs.io/en/latest/layers/automotive.html#uds

I've implemented some basic security access as part of a UDS scanner, but the authentication function can be used stand alone aswell. Maybe you want to have a look at...

Automotive - ISOTPSoftSocket: Bug fixes and performance improvements - Documentation and API-Doc improvements - Unit-Test speedups for Scanners - IPv6 support for DoIP - Bugfixes for DoIP - Unit-Test cleanups...

Another question, have you tried to use the argument :param frame_txtime: Separation time between two CAN frames during send on your ISOTPSocket?

Well, CANFD is already added to most parts. Just the ISOTPSoftSocket doesn’t support FD yet. Feel free to submit a PR.
