Here is my code. i think that is the same example as you send me. Now i can through the browser control the LED on and off, that can also know the status of button. but i can’t on my iphone open this example to control that.I also no idea how can i do that. Could you please tell me what should i do, if I want do control the LED on my iphone just like on mac. thank you so much!!!

$(document).ready(function() {
    // Declare these variables so you don't have
    // to type the full namespace
    var IOBoard = BO.IOBoard;
    var IOBoardEvent = BO.IOBoardEvent;
    var LED = BO.io.LED;
    var Button = BO.io.Button;
    var ButtonEvent = BO.io.ButtonEvent;

    // Set to true to print debug messages to console
    BO.enableDebugging = true; 
    
    // If you are not serving this file from the same computer
    // that the Arduino board is connected to, replace
    // window.location.hostname with the IP address or hostname
    // of the computer that the Arduino board is connected to.
    var host = "88.67.48.195"; 
    //window.location.hostname;
    // if the file is opened locally, set the host to "localhost"
    if (window.location.protocol.indexOf("file:") === 0) {
        host = "localhost";
    }

    // attach fastclick to avoid 300ms click delay on mobile devices
    FastClick.attach(document.body);

    var arduino = new IOBoard(host, 8887);
    
    // Variables
    var led;
    var button;
    var $state = $('#state');
    var $schematic = $('#schematic');

    // Handle showing and hiding the schematic
    $('#schematicBtn').on('click', toggleSchematicView);    

    // Listen for the IOBoard READY event which indicates the IOBoard
    // is ready to send and receive data
    arduino.addEventListener(IOBoardEvent.READY, onReady);

Thank you again!!! Just like you say, my iphone is connecting to the same Wi-Fi Network as my computer. And my Firewall will also be disable. so i think that can absolute port 8887 get through, am i right? but when i open with http://IP-adress:8887/examples, that show me nothing.(it is connected, but there are nothing in there.) I have also tried through hostname.local:8887/examples to open it, but that doesn’t work either. If i use Phonegap (port:3000) that html can open on my phone . I guess that mean, my mac has maybe no problem. Have a idea, where is the Problem, or i do something wrong?

Thank you very much!

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
