Not sending frames in sequence
tvesalainen opened this issue · 2 comments
I was testing cannelloni with following command:
cannelloni -l 10000 -p -t 10 -R 224.0.0.3 -I can1
I noticed that there are gaps in seqNo field. 24, 26, 28. SeqNo's 25 and 27 are missing.
Following is a print of
tcpdump -x port 20000
at the same host as cannelloni is running.

Do you have logs of the interface can1? This would prove that 25 & 27 actually arrived on the physical interface.
To enable logging in cannelloni, use: -d cu - this will print CAN frames in a similar fashion like candump does.
Closing because of inactivity.
