Hello everyone! I started with an ESP8266 few months ago and I've been able to build certain projects that involve most of the popular libs/stacks. I used PlatformIO with Arduino Platform.

After doing a bit of research, I found that these devices are supported by dozens of communities and resources, however, this abundance of resources and materials sometimes makes it really confusing for ...
