I am using ROS2 Dashing, I am trying to write value to /turtle1/cmd_vel from an external program using OpenSplice DDS. When using the command ros2 topic echo /turtle1/cmd_vel I saw the linear and angular values are updating according to the values I sent but turtlesim is not moving. Any advice on how should I troubleshoot this issue?

Additional Information, I used the .idl file generated from source build to generate the geometry_msgs::msg::dds_::Twist_ datatype for the OpenSplice DDS message sent.

Thank you very much for your time.
