Describe your question.

I have performed a fresh install of Ubuntu Server 22.04 on a Raspberry Pi 4 and have gone through the ROS 2 Humble config and added it to my Create. However, I am not seeing the Create3 topics show when listed.
I can ping the Robot IP 192.168.186.2 from the RasPi 4, but still no go.

Am I missing a step somewhere?

I have tried to run the run the troubleshooting.py script, but it calls iwgetid which is not installed, so I commented this and just added a generic wifi values since this should not be necessary.

This is what I see when I run 'ros2 topic list'

$ ros2 topic list
/parameter_events
/rosout

This is the output of the troubleshooting.py script:

$ python3 troubleshooting.py
This program will cross-check all relevant settings on your computer and robot to expedite troubleshooting. Please fully reboot the robot and wait for the start up chime before proceeding
Have you rebooted and waited for the chime? (Y/n) y

Wi-Fi Connection:
WARNING! No Wi-Fi network was found in the robot's logs. This means one of two things:
1. The robot is not connected to Wi-Fi. If you wish to use the robot on Wi-Fi go to the
connect page on the robot's webserver and connect to a network.
2. The logs are too old to show the most recent connection. If you believe the robot
is connected to a Wi-Fi network please fully reboot the robot, wait for the
startup chime, and run this script again.

Okay, I solved the issue.

I ended up running

$ rosdep init
$ rodep update

And now I can see the topics:

$ ros2 topic list
/battery_state
/cliff_intensity
/cmd_audio
/cmd_lightring
/cmd_vel
/dock_status
/hazard_detection
/imu
/interface_buttons
/ir_intensity
/ir_opcode
/kidnap_status
/mobility_monitor/transition_event
/mouse
/odom
/parameter_events
/robot_state/transition_event
/rosout
/slip_status

I'm really struggling with the same issue and this didn't work for me. Could you possibly go through the steps you take from fresh install to running ros2 topic list? @jomoengineer
