Hi everyone
I’m trying to check the content of the topics related to goal, feedback and result of the ardrone node but after running
roslaunch ardrone_as action_server.launch &
and
rostopic echo /ardrone_action_server/goal
in two different shell the message I get is
WARNING: no messages received and simulated time is active.
Is /clock being published?
I dont know what I’m missing
Thanks in advance
I have the same problem when testing the Fibonacci example.
Thanks again
Hi, the action server does not actively publish the action topic itself, it just makes it available on rostopic list. The publishing happens once you call the action server. I recommend you finish that section in order to understand how it works. You can call the server while you have a rostopic echo on another shell, and you’ll see when messages are being published through that topic.
Thanks Rodrigo! I realised after finishing the lessons.
Thanks again
