Why do you want to use lua, do you have an existing project or code using it?
Why have you chosen ESPlorer? the Arduino IDE (for example) is much more common, so easier to get help with when you are learning/playing?
Do you have a particular thing in mind that you are trying to make?
Also, the ESP-12 comes with Nodemcu(lua), but is easily flashed using Arduino IDE (and put back to lua with ESPFlasher), so it just becomes ‘another simple/basic mcu’, but obviously having WiFi built in.
when I started with ESP8266 I thought that using Lua was easier than with Arduino IDE.
After sometime I have to say that was not true, so I’m going to use it.
Actually, I found some interesting project written in Lua that I would like to integrate, but I see that “converting” from Lua to Arduino IDE is not so simple.
