Hi, have you changed AP_SSID, AP_PASSWORD and SERVER_IP in Esp8266EasyIoTConfig.h? This important to change, so its able to connect to your wifi network and finds your Easy IOT server.
Or is this an compilation error? Or you did not use the example under examples_standalone?
BTW. I compiled this with Arduino IDE 1.6.8.
One thing you should do is to use a serial terminal program to see what it outputs (Same pins as used for programmer).
