As I read I understand that all topics messages are displayed in rosout topic. But as I see the messages that are different than a simple string aren't displayed, isn't it?
So what can I do if I want to show all the messages from all topics?. Is there a log file? or can I change the rosout configuration?. Perhaps the unique method is to subscribe to every topic?
Thank you.
rosout does not display all topics! It displays information send from programs via ROS_INFO/ROS_WARN, etc.
You can look at any message via: rostopic echo <topic>.
And yes, there are logging facilities. Look for rosrecord and rosbag.
Ok I saw that some topic were published in rosout a ROS_INFO.
Rosrecord is deprecated. Rosbag could help me. But as I see it generate binary files. I saw that it's format is published, perhaps I can read it. My idea is to read the message of topics in real time, like subscribing them, but I want to subscribe to more than one. Now, the better way to do it that I found is to redirect de desired topics with the rostopic echo. Also I can program a node that could subscribe to more than one node? I have to think which could be the better way.
Thank you
