I have a question about preparing and downloading firmware from https://nodemcu-build.com/
I have download this custom build module. This is great for LUA scripting and programming and I always do it with LUA. Simple and stable, works great as mqtt esp client doing stuff.
Does this same firmware supports uploading arduino code or this is some another story? My friend have arduino coded into esp8266-01 and he told me that firmware is the same. Is he right?
