I wrote my ip address directly in code like this.

var arduino = new IOBoard(“xxx.xxx.x.xxx”, 8887);

I think in this way, the Arduino must through my ip address to visit the code maybe. Whatever, on this way it can perfectly work. but if I write the address in browser, i can find nothing, no matter on my laptop(Mac) or my iphone.That seems like there are no data here. btw my browser is Safari.

thank you so much !!! T_T
