What is the best way to program ESP8266?

Question

Arduino

Recently I started to understand the ESP8266 modules, developed some test firmware for it using the Arduino IDE, as well as some using Mongoose OS. I know that there are still NodeMCU and other IDEs, as well as an SDK from the manufacturer. Thus, the choice is very large. But which of these is better to choose if the goal is not a toy for entertainment, but a commercial serial device?

Answer 1

If everything is so serious, then they usually choose C and write a closed custom firmware. Usually they take something as close as possible to the hardware (C / asm) with the ability to assemble in .HEX

Although stable work can be achieved on lua / Arduino IDE.

Answer 2

For esp8266, I have not yet seen a more stable firmware than " dump from pvvx "

Answer 3

PlatformIO in my opinion one of the best in terms of ease of use
