I want to use Corona to write serious apps. (Look up "serious game" on Wikipedia. It's the same animal.) Part of my motivation is work-related, and part is hobby-related.
On the work-related side, I work for a company that makes an edge computer. It runs Debian on an ARM processor. No, it's not a RPi -- but I have a RPi 3B on my desk, for feasibility and prototyping work. Anyway, our computer has Ethernet access, both wired and WiFi. Users can connect to it through HTTP, HTTPS, SSH and an HTML-based REST API.
So as a skunk-works project, I'm writing two apps for it.
1. The first is one that will allow a user to configure and manage a fleet of these devices. I thought this was an original idea, until I saw the RaspController app for Android.
2. The second is an MQTT Listener, basically a client that subscribes to an MQTT broker and spews out all the messages that the broker receives. The Google app store already lists a lot of these as well. I just wanted to try to do it using Corona and Lua.
On the hobby-related side, I'm building my own garage door opener remote-control app. I've got a RPi connected to a Hall-effect sensor, a camera, and a relay, and I use a rudimentary webpage to check the status of the garage door and "push the button, Max". I want to go from the webpage to a smartphone app. Corona would be perfect for this. So after I make significant progress on the skunk-works project, I'll apply my learnings to the garage door.
