<h1>Welcome to FatBeacon!</h1>

<div class="card">

<p>A FatBeacon is an experimental beacon type for offline web pages. A FatBeacon does two things:</p>
53+
<ul>
54+
<li>It advertises the name of the device</li>
55+
<li>Runs a <a href="https://developer.bluetooth.org/TechnologyOverview/pages/gatt.aspx">GATT</a> service that offers up a simple web page.</li>
56+
</ul>
57+
<p>When you select a FatBeacon from the list of nearby beacons, the app connects to it and downloads to page to your phone before displaying it. This means you can interact with a FatBeacon with no data connectivity at all.</p>
