# Scan For Bluetooth Devices

## Overview

![The Scan For Bluetooth Devices Node.](/files/VDMTeDj8rooni7ROPSLZ)

The **Scan For Bluetooth Devices Node** searches for *Bluetooth* devices in the short-range vicinity and returns any found in an **Array** of **Dictionaries**. The *keys* of these **Dictionaries** are `Device Name`, `Device Address`, `Service Class`, and `Device Class`.

**Bluetooth Communication** in **Incari** is available as a plugin and is enabled as default. However, in the case that it is disabled in the **Plugins Editor**, it will not appear in the **Project Settings** and **Scan For Bluetooth Devices** will not show up in the [**Toolbox**](/incari-studio/2024.1/toolbox/overview.md). Please refer to the [**Plugins Editor**](/incari-studio/2024.1/modules/plugins.md) to find out more information.

[**Scope**](/incari-studio/2024.1/toolbox/overview.md#scopes): **Project**, **Scene**.
