How is it possible to publish the content of a string in a ROS topic? Unfortunately only the topic is created, but the content (msg.Data = 'xyz') is not transmitted. The instructions on mathworks (https://www.mathworks.com/help/ros/ref/send.html) to send messages on ROS does not produce any result.
Using 30 days trail version of MATLAB 2020b with Robotics toolbox.
Thanks in advance!
