I am new to ROS and have inherited simple code to subscribe and monitor topic on a remote node. The code is using ws4py's WebSocketClient, connecting to wss://myhost/ws, subscribing to the topic by sending {'op':'subscribe','topic':'mynode/mytopic'} request. The messages are coming just fine.
How do I list all topics published by myhost/mynode using a websocket request?
Would it be better to use rospy for higher-level access?
I tried some google-fu, no result, found only rosbridge protocol description, but it does not mention listing topics.
Thanks for help!
