Windows Mobile 6.x HTML5 NPAPI plugin
Visual Studio 2008 Windows Mobile 6 Prof. SDK
HTML5 Browser
This plugin offers a NPAPI object to retrieve the Model Code, RSSI, Battery Level of a supported device.
Copy the plugin DLL to the plugins directory of the browser. For example "\Program Files\HTML5 Browser\plugins" or "\Program Files\Enterprise Browser\plugins". No further installation needed. Just use the embedd tag and the DevInfo object as described below.
Note that the plugin may not work if the html is not loaded from a web server.
First create a new embedding.
</HEAD>
<embed id="embed1" type="application/x-itc-devinfo" hidden=true> </embed>
<BODY>
Then create a new object
<script>
var devinfoObj = null;
if (devinfoObj == null) {
devinfoObj = new MyDevinfo();
}
else {
alert('devinfo object already created');
}
...
The following returns a string with the mode code:
devinfoObj.modelCode;
The following script code returns the battery life percent
devinfoObj.currentBatteryLevel
The RSSI in dBm is returned by the following property
devinfoObj.currentRSSIValue
The first local IP address returned by following property
devinfoObj.localIP
The first local MAC address returned by following property
devinfoObj.localMAC
Setting an interval and enabling the monitor will call the javascript function periodically
devinfoObj.pollInterval=1000
the pollInterval has to be set in milliseconds.
devinfoObj.monitor(boolean);
use true to enabling periodic callbacks and false to disable the callback.
The callback function has to be named onBattRssiUpdate and uses two arguments:
function onBattRssiUpdate(batt, rssi){
//do something with the supplied values
}
Normally place the embed object inside the <body> tag.
If the object will not inialize correctly during HTML loading, you may use a delayed initialisation to autload the object. For example:
<HEAD>
...
<script>
var devinfoObj = null;
function olinit() {
if (devinfoObj == null) {
devinfoObj = new MyDevinfo();
if (devinfoObj == null) {
alert('devinfo object NOT created');
}
}
else {
alert('devinfo object already created');
}
}
</script>
<embed id="embed1" type="application/x-itc-devinfo" hidden=true> </embed>
</HEAD>
<!-- creating the object automatically must be delayed -->
<BODY >
