[erlu02]

Hi
I found this cool project on Thingiverse and deside to built it. But I have a software problem where I need your Help. When i try to upload you code i get an "exit status 1" with the text

esp8266-fastled-desk-light:226:21: error: 'WIFI_NONE_SLEEP' was not declared in this scope

WiFi.setSleepMode(WIFI_NONE_SLEEP);

                 ^

exit status 1
'class ESP8266WiFiClass' has no member named 'setSleepMode' "

It woud be cool if you can help me so that i can finish this project soon and very good.

Thanks in advance,
Erik
