Hello,
I am using R2025a, on Windows 11. I have installed the ROS toolbox, along with python 3.10.x.
Every time I issue a ros command, eg ros2node("/foo") or even ros2 node list, or whatever command in general, matlab hangs.
The program is not frozen, however it is as if the command never finishes execution. I've allowed for up to 30m of execution time, and I get nothing on the output window (and of course matlab is indicating "Busy").
The computer has all firewalls/antivirus software/whatnot completely disabled, so this must not be an issue here.
What I have tried:
1) Reinstall ROS addon
2) Try all three RMW implementations
In all cases, there was no difference in the outcome.
I've never seen this before, any ideas what it could be?
Thanks,
Konstantinos

Hey Konstantinos,
I see that you’re having trouble with MATLAB hanging when running ROS commands from the command window. I’ve tried the same steps, but I cannot reproduce the issue since the commands are working properly for me.
However, you can try clearing the folder “C:\ProgramData\eprosima” by closing all instances of MATLAB and restart MATLAB. This should remove logs, configs, and cache for eProsima middleware and help in resolving the issue.
Hope this helps!

Thanks, removing that folder worked like a charm. I didn't know this folder existed, let alone it might be caching anything.
For anyone else having a similar issue, feel free to try.
