ESP8266 core for Arduino

Hey Guys,

I can't install the ESP8266 by ESP8266 Community

I put in the additional boards manager.. the

http://arduino.esp8266.com/stable/package_esp8266com_index.json

url, but I can't find it there.

So I put the https://github.com/esp8266/Arduino/releases/download/2.3.0/package_esp8266com_index.json

url there. But I got no update for the Board.

I reinstalled it 3 times (3 Software Versions).

I delete the folder: C/users/me/appdata/local/Arduino15 and the folder with lib and the scetches.

Nothing work and I will kill this PC soon ^^

Plz help!!

What do you mean by "I can't find it there"?

Don't use those version-specific JSON files. They won't be updated when there is a new release so you'll eventually end up using an outdated version of the ESP8266 core.
