How is the not-really-an-Arduino supposed to communicate with the server? Do you have an ethernet shield?

If not, you need to get one.

I need to communicate via Wi-Fi . i have LinkIt One (The Ultimate Developer Board for Wearables and Internet of Things.) -by MediaTEK labs .

i already tried with MediaTekSandbox (Development > Test devices > LED Control). the LED works perfectly. now i want to develop LED Control without MediaTekSandbox.
