<p>The <strong><code>Bluetooth</code></strong> interface of the <a href="/en-US/docs/Web/API/Web_Bluetooth_API">Web Bluetooth API</a> returns a {{jsxref("Promise")}} to a {{domxref("BluetoothDevice")}} object with the specified options.</p>

 <dd>Returns a reference to the device, if any, from which the user opened the current page. For example, an Eddystone beacon might advertise a URL, which the user agent allows the user to open. A BluetoothDevice representing the beacon would be available through <code>navigator.bluetooth.referringDevice</code>.</dd>

<h3 id="Events">Events</h3>

<dl>
 <dt>{{domxref("Bluetooth.onavailabilitychanged")}}</dt>
 <dd>An event handler that runs when an event of type {{event("availabilitychanged")}} has fired.</dd>
</dl>

<h2 id="Methods">Methods</h2>

<dl>
 <dt>{{domxref("Bluetooth.getAvailability()")}}</dt>
 <dd>Returns a {{jsxref("Promise")}} that resolved to a {{jsxref("Boolean")}} indicating whether the user-agent has the ability to support Bluetooth. Some user-agents let the user configure an option that affects what is returned by this value. If this option is set, that is the value returned by this method.</dd>
 <dt>{{domxref("Bluetooth.requestDevice()")}}</dt>
 <dd>Returns a {{jsxref("Promise")}} to a {{domxref("BluetoothDevice")}} object with the specified options.</dd>
