hi RickHaleParker ,

thanks for the useful tips

The Arduino code has a CAN-bus reset routine, which brings all devices back to live. You may want to add progModeOff(); as a last line in setup() function and remove everything from the loop() function.

>>> more is not possible >>>

why does the program not continue

You have no jumpers on J1, the end of bus is not terminated, lots of signal reflections.

Should I set a jumper on both CAN bus shields
put a jumper on J1?
Can you please help me out,
I do not have so much experience with it,
but I would like to complete this project successfully.

On both shields.

Thanks vtl for your helpful tips,
I will try again tomorrow with Jumper on J1, of course if it does not snow tomorrow or is too cold outside.

I can't be of any help "testing-wise", I still need to do some other things before I can even think about ordering the parts.

But if there are language barriers between english and german, I'm happy to help!

It is good, but very expensive for the task.
