ROS2 support state

I got the notification regarding your issue @jacob-CyberB and noticed I forgot to update this post! :sweat_smile:

While I can’t say anything about your problem (it’s not something I’ve encountered), I can leave some useful reference for what I was facing myself.
It turned out, after some more testing and debugging, that my problem of not being able to see nodes and topics with ROS2 was due to the ROS_DOMAIN_ID variable I set in .bashrc.
Once that once commented out, I was able to see everything correctly.
Here’s the GitHub issue that unlocked that knowledge for me, so to speak.


EDIT: to be precise, I too have seen the paramftp: bad count XXXX should be YYYY warning, both myself and during a debug session, but it didn’t seem to cause any problem. I might be wrong though!

@jacob-CyberB have you figured out the problem? I’m having exactly the same issue. xrce agent keeps crashing on me with std::bad_array_new_length.
@rfriedman Hi there, can I set up a troubleshooting session with you?

Sorry for missing this; can someone who is facing the bad array length problem file an issue on the eProsima’s issue tracker here? Issues · eProsima/Micro-XRCE-DDS-Agent · GitHub
Then, post the issue here, so I can assist.

It would be helpful to know what platform this is occurring on, and what commit hash of ArduPilot you are running.

I haven’t ran into it myself yet, so I’ll need some guidance on how to reproduce it.

Thanks!
