isotprecv works the other way around.
:-D Yes. Trapped into this myself some times.
Btw. @Marvin are you really sure with the given values for the CAN IDs?
The help text says:
Usage: isotpsend [options] <CAN interface>
Options:
-s <can_id> (source can_id. Use 8 digits for extended IDs)
-d <can_id> (destination can_id. Use 8 digits for extended IDs)
So your IDs 00000680 and 00000780 are 29 bit CAN identifiers!
Is this intentionally?
Some people mix up the nominal values with the 11/29-bit IDs and think
every CAN ID below 0x800 is a 11 bit CAN ID.
