After fooling around with NSStream configuration, my old good iPad finally talks to my PC over LibO Impress.
With the help from LibreOffice community, I’ve just succeeded in getting my iPad to display slideshow previews sent from my computer.
Here is what it can do for now:
1. Connect to PC with an iP address (given that your PC and iPad are connected to the same WiFi network)
2. Listen for instructions from PC.
3. Automatically switch to a slides preview page where you can have some screenshots of your current slide and the lecturer’s note accompanied with.
Finally, a screenshot to whip your appetite!
