Manipulating Variables in the Application Website

The application website is composed of HTML or WAP files, which may contain links to internal

or external websites, Java Scripts, VB scripts, graphic files, and more (See list of supported file

types). Using Parameter Tags, the page can also be used to dynamically display and update values

of W24's configuration parameters and device-specific Parameter Tags in the manner described

above.

For example, to display the current value of the headline web parameter, enter ~headline~

anywhere on the page, as in the following example:

<HTML>

<HEAD>

<TITLE>SAMPLE PAGE</TITLE>

</HEAD>

<BODY>

<h1>~headline~</h1>

</BODY>

</HTML>

When serving this home page, W24's web server replaces the ~headline~ string in the served page

with the current value of that parameter.

For example, if the host issues:

AT+iheadline="Hello world"

A browser pointing to W24's URL address will display the image as seen on the right.

To update W24 configuration parameters via the web page, simply use W24's parameter names

(excluding the AT+i prefix) in an HTML form.

For example:

<HTML>

<HEAD>

<TITLE>SAMPLE PAGE</TITLE>

</HEAD>
