<div class="ui info message">
<div class="content">
<p><img class="ui image" src="/static/bluetooth/Bluetooth_SIG.png" alt=""></p>
<p>For another device like a smartphone to use any of the Bluetooth “services” which the Calliope mini has, it must first be <a href="/pxt-calliope/docs/reference/bluetooth/bluetooth-pairing.html">paired with the Calliope mini</a>. Once paired, the other device may connect to the Calliope mini and exchange data relating to many of the Calliope mini’s features.</p>
</div>
</div>
<p>The Bluetooth IO pin service makes it possible for another device such as a smartphone to communicate with other electronic ‘things’ connected to a Calliope mini’s edge connector. You could for example, use your smartphone to switch on or off a light which is connected to the Calliope mini or your smartphone could receive data collected from a sensor connected to the Calliope mini. In fact you could do both of these things at the same time since the Bluetooth IO pin service lets you interact with multiple ‘pins’ on the edge conector in different ways all at the same time. </p>
<p>No additional code is needed on the Calliope mini to use the Bluetooth IO pin service from another device. </p>
<pre><code class="lang-sig">bluetooth.startIOPinService();</code></pre>
<h3 id="example-starting-the-bluetooth-io-pin-service">Example: Starting the Bluetooth IO pin service</h3>
<p>The following code shows the Bluetooth IO pin service being started:</p>
<pre><code class="lang-blocks">bluetooth.startIOPinService();</code></pre>
