To test the ESP, the Arduino system is good enough. I'll explain here the steps to install it.
- Install the Arduino software
Install the Arduino software from the official website (http://www.arduino.cc).
- Go to the preferences and add:
in the Additional Board Managers.
Go the the Board Manager and choose ESP8266, install it
Choose the Generic ESP8266 in the boards list
It worked out-of-the-box on my main machine (ArchLinux) and on another one (Debian Sid).
Of course, you have to trade the ease-of-use for the weight of the Arduino Libs… Pick your side.
