I'll start a project using NodeMCU V3 WiFi Module, which uses esp8266 chip. However, I am undecided as to which library to use. I don't want use a serial bridge with an arduino, I think it is better to use NodeMcu in Standalone mode.

So, here's my question: which library should I use? And, regarding the type of use, what is their difference? (both libraries reference looks like the same for me)

p.s.: I also heard about the "WiFi.h" library. Does it work only on WiFi shields for arduino or does it also work on esp8266?

It's quite simple:

  • ESP8266WiFi.h - Runs on the ESP8266 to control the WiFi.
  • WiFiEsp.h - Runs on an Arduino to communicate with an ESP8266 module with AT commands
  • WiFi.h - Runs on an Arduino to work with the Arduino WiFi shield.

So the one you want, which is part of the ESP8266 core, is ESP8266WiFi.h.

  • Thanks! But let me ask you one more question: is the syntax the same for both libraries? At least in the examples I saw, they looked the same. – joaov_machado Apr 4 at 11:42
  • No idea. Probably only superficially of at all. – Majenko Apr 4 at 11:43
