Hi there @xylhal
Thanks for reaching out.
"Sometimes, when I restart Rviz and the turtlebot, " after rebooting are you sshing in again and relaunching RVIZ? Can you please provide the terminal outputs with any errors?
Thank you, Rusty
Hi there @RustyCPR
I'm actually not launching rviz from the RPi. I am running everything remotely from another machine. So, I didn't do any ssh. What I meant by restarting rviz and turtlebot simply means physically restarting the turtlebot and creating a new terminal on my remote machine to start rviz.
I've attached 5 images below.
Please let me know how else can I debug this?
I would add that I realize sometimes the terminal does print some messages when echoing the topic, but the Rviz remains blank.
Hi @xylhal
Run: ros2 launch turtlebot4_viz view_model.launch.py
if your not using mapping
Point 5 image with error "A message was lost!!!
" What type of wifi network are you running?
If you're on a 2.4GHz network can you try a faster 5GHz?
Regards, Rusty
