This action starts the discovery process. When a Bluetooth device is discovered the event **Bluetooth Device Found** will be executed on the top form.
{% endhint %}

{% hint style="info" %}
When the discovery process is finished the event **Bluetooth Discovery Finished** will be executed on the top form.

{% hint style="info" %}
On some Windows CE/Mobile devices this function may not be available. It will depend on the actual Bluetooth drivers of the device.
