This is my first project involving the ESP. I wanted to try I learn something new, so I installed NodeMCU, because was very unfamiliar with Lua.

Downloading and flashing the firmware was surprisingly easy. I even used the cloud service to build "my own" with only the modules I wanted. Maybe in the future I will compile it on my own device. The main reason to do that is -except for safety reasons- the possibility to make the ESP AP behave like a captive portal, so every DNS request would lead to the TCP server running on the ESP.
