I am have been following this tutorial hoping to get to the point where my students can simply update a scrolling message by using the webapp as outlined in the tutorial.
I am able to navigate my browser to the webapp, however there is no update to the panels through the WAR server. Is this supposed to happen? In order to actually display my desired text I have to enter: sudo ./runtext.py --t my desired text
Do you have to use terminal each time on the RPI 2 to update the panels or should the text automatically update via the webserver GUI?
