Hows that for trying to confuse bots?

I'm interested. I have ordered a Flipper Zero and should have it at the end of this week. I really want to see CAN added to Flipper. And, being able to then interface that to SavvyCAN would be nice. I'll keep an eye on the pull request over at the link you posted.

if you are ready to add support to the program, I am ready to do whatever is needed from the flipper side

[Skorpionm]

but for CAN FD/Lin to work on the flipper, an additional module is required, which is not yet available.

I can implement any work protocol. all you need is a description of it.
the can chacker 2 (lawicel) protocol is now implemented, but it does not support Lin and CAN FD

This document describes the GVRET protocol I use to communicate with my SavvyCAN program: https://github.com/collin80/M2RET/blob/master/CommProtocol.txt

I'm thinking to build a CAN board, at least temporarily for my own use. I have the protoboards for flipper coming with it so I should be able to rig something up to test CAN at least.

Sorry, this is not a complete protocol at all, there are no Lin frames, no examples of packets and responses to them, no algorithm for calculating checksums. and other things. It would be nice to have at least a trace of communication between the device and your program, ideally with comments about what you are sending and signatures of packet types
https://github.com/collin80/M2RET/blob/master/M2RET.ino
https://github.com/collin80/SavvyCAN/blob/master/connections/gvretserial.cpp

it's more clear. yes I can implement such a protocol. but the question is, is this a protocol invented by you or from some standard piece of hardware? As I understand it, it lacks support for CAN FD packets, installation of a master mode for lin, it is not clear with time stamps of packets, and some other subtleties. And is this protocol more fully supported in your program?
