No data being streamed on topics

[ghost]

Environment
Motive version: 2.1.1
ROS distribution: Melodic
Operating system: Ubuntu 18.04.5
Python version: 2.7.17

natnet_ros version
natnet_ros branch: master
natnet_ros commit: a859ada

First of all: Thank you for creating this package which helped me a lot already.
This is not a bug report, in fact there is not even an error message. When I run

natnet_ros client _server:=172.16.0.3

a connection between the ROS PC and the Motive PC seems to be correctly established, because all the topics are listed:

rostopic list
/mocap/markers/leftovers
/mocap/markers/vis
/mocap/rigid_bodies/ball/marker1
/mocap/rigid_bodies/ball/marker2
/mocap/rigid_bodies/ball/marker3
/mocap/rigid_bodies/ball/marker4
/mocap/rigid_bodies/ball/marker5
/mocap/rigid_bodies/ball/markers
/mocap/rigid_bodies/ball/pose
/rosout
/rosout_agg
/tf

However, no motive data is being published on the topics, i.e.

rostopic echo /mocap/rigid_bodies/ball/pose 

returns nothing. The same is true for all the other topics. Since the ball is correctly tracked in Motive, I assume that the problem has to be somewhere in the data streaming. Unfortunately, I have no idea where to search the error, because obviously the streaming of the model definitions works fine. Otherwise, the topics would not be generated.
I would be very glad for any advice you could give me. Thanks in advance!

Thanks for the report, could you post a screenshot of your streaming settings in Motive?

Thanks for the quick response, here are the settings:

From memory I think you need “labelled markers” on as well or something, let me know if any of those fix it.

Unfortunately, that as well as changing the other options in the streaming tab did not solve the issue.
However, this warning might be worth mentioning:

Could these warnings be related to the problem? I am still confused about how the correct topics are being generated but no data is being streamed onto them.

Nope, but I have created a new package with more features for ros1 if would you like to use for
Ros1 (https://github.com/aarsht7/natnet_ros_cpp)

For ros2 you can follow this package but its WIP
Ros2 (https://github.com/MOCAP4ROS2-Project/mocap4ros2_optitrack)
