Hey!

When debugging actions, I often do a rostopic echo on the goal and result topic. However, I haven't found similar topics for services. How can I listen to this communication?

With rosservice you can not get into the communication, you can just call a existing service

rosservice options -> call  find  list  type  uri

Services are not topics. I guess there is no way to look into it, there is only one service with the same name allowed. Because services are blocking calls, like function calls. So to listen to a service, you must provide it, but I guess there is no way to "listen" to it if you are not the call receiver.

ok, thanks. I guess I just have to use actions.
