ROS_Comm and ROS_Telemetry failed to connect to ROS

[Salmon490]

Hi,

An issue that I am encounter is when I run the sim, then run rosbridge_image_client.launch.py, ROS_Comm and ROS_Telemetry will fail to connect so I can't run the example_client.py. I was able to run it a few days ago but now I can't. How do I resolve this issue

Start sim:
ImageSender started properly.
ROS_Telemetry started properly.
EventHandler started properly.
ROS_Comm started properly.
WaypointScatter started properly.
Starting ImageSender Loop

Then I ran:
ros2 launch space_teams_python rosbridge_image_client.launch.py

Then it prints:
ROS_Comm failed to connect to ROS. Please restart the sim after ROSBridge is running.
ROS_Telemetry failed to connect to ROS. Please restart the sim after ROSBridge is running.

You may need to instead have the rosbridge_image_client.launch.py running already before starting the sim. This script won't start the driving time timer; that is dependent on the driving commands called by example_client.

So, you can start example_client after getting the sim working with images passing.

Also, if there isn't reporting of image FPS in that ROS terminal, you may need to end and restart ros2 launch space_teams_python rosbridge_image_client.launch.py to reconnect the image client.
