I get "no new messages" when I try rostopic hz. rostopic echo remains empty on the topic.

OK, so the issue is on the server side, not the client side.

Can you send me the output of nhfc-ros -d ? (or the beginning at
least, once it's started it's supposed to output loads of lines).

nvidia@jetsonTest:~$ nhfc-ros -d

OK, seems normal.
What version of the main ROS packages do you have?

I don't quite understand your request, could you explain a little bit more into detail what you want please ?

We do use ros kinetic on the Jetson as well as on the Odroid. Otherwise we have libros-client-1.18.so

All packages have been updated to the latest update with the proper PKGOPTIONS

I was thinking about something like dpkg -l \*roslib \*roscpp \*actionlib
But if it's kinetic it should be fine, then.

I just tried on our odroid-c2, everything is working as expected:

So at the moment I have no clue as to what is happening.
When you do the rostopic hz /nhfc/genom_state, do you see traffic on
the loopback interfane, similar to that below?

Ok I do not have anything odd compared to you but it is not working yet.

I will keep investigating on my side

You could also try the following dumb test:

fritillary[~] > rostopic pub -r 1 /test std_msgs/Int32 42

fritillary[~] > rostopic hz /test
subscribed to [/test]

my very bad, it seems that ros logs were too big "(.ros/log] is over 1GB.)". Doing a 'rosclean purge' simply solved our issue. It has been a while since this happened to me. Since the quadrotor was used remotely I did not understand this at first. Thank you for your time and sorry for the inconvenience.
