Method to know if a service server on ROS side is up and ready #158
Description
Is your feature request related to a problem? Please describe.
There doesn't seem to be a method in ROS TCP Endpoint / Connector to check if a service server on ROS side is ready to use so I can send a request from unity side properly.
Describe the solution you'd like
- Add a method equivalent to
wait_for_serviceof rclpy - Or add a method to know if a service server on ROS side is ready or not from Unity side
- Or add a method to list service servers on ROS side
Describe alternatives you've considered
- Send requests to service server without knowing if it's ready or not.
- Create a new publisher on ROS side to notify unity side that a service server is up and ready.
Additional context
I'm using ROS2 Galactic, and I don't understand enough about the compatibility with ROS1.
