I have a Turtlebot4 connected to an other PC (Ubuntu 22.04) with its acces point.
My mac is also connected to the PC.
I can't see every topics on my mac and I suppose it's because of the DDS.
Turtlebot4 and the PC use fast DDS.
With RoboStack on ROS2 Humble on my mac I have Cyclone DDS.
When I try to use it I get an error :
$ export RMW_IMPLEMENTATION=rmw_fastrtps_cpp
$ ros2 daemon stop;ros2 daemon start
The daemon has been stopped
The daemon has been started
$ ros2 topic list
