But I found after I clicked in the webpage, LED status will be changed after more than five seconds with big chance to fail!
No matter use NodeMcu LUA or Arduino
I don't know why, can't get the answer, I thought it is my program's problem.
This changed after I bought ESP8266-12F, same program but different result!
Now when I click in the webpage, LED status will be changed immediately!
Finally I start to love ESP8266, don't know why there is different from ESP8266-01 and ESP8266-12F
