Errors on startup and test node launch

edit

I deployed ROS2 on a Windows OS computer, when I call local_setup.bat or setup.bat, I get the error

[connext_cmake_module] Warning: The location at which Connext was found when the workspace was built [[C:\Program Files\rti_connext_dds-5.3.1]] does not point to a valid directory, and the NDDSHOME environment variable has not been set. Support for Connext will not be available.

I do not understand why, because I use OpenSplice DDS and I have registered the variable OSPL_HOME.

Further.

When you run

ros2 run demo_nodes_cpp talker

nothing happens that's all that is displayed

C: \ Users \ TestUser> ros2 run demo_nodes_cpp talker

C: \ Users \ TestUser>

where the punt field is there is waiting. Modem lasts up to 1 or 2 minutes
