Hey hey all!

I'm back from hospital, so do expect more posts from me :-)

Got a problem with my project, microRos agent is launched and serial communciation with Teensy is established but I can't see any topics, nor services.

Raspberry pi 4b (headless server) running ubuntu 22.04.1 and ros humble -> MicroROS agent Teensy 4.1 running microROS

$ cat logs/microros/agent.log
