# Is Bluetooth Device Paired

## Overview

![The Is Bluetooth Device Paired Node.](/files/R1KWHjKavOlWkOErnV23)

The **Is Bluetooth Device Paired Node** checks the pairing status of a *Bluetooth* device to the [**Bluetooth Plugin**](/incari-studio/modules/plugins/communication/bluetooth.md).

The **Node** only schedules the 'is paired' checking process and then returns immediately. This means that it is possible to trigger the **Node** multiple times with different inputs, resulting in consecutive checking attempts. This is the reason for returning the error *Bluetooth* address, as it properly attributes the error to the relevant device.

**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 **Is Bluetooth Device Paired** will not show up in the [**Toolbox**](/incari-studio/toolbox/overview.md). Please refer to the [**Plugins Editor**](/incari-studio/modules/plugins.md) to find out more information.

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

## Inputs

| Input               | Type       | Description                                                                     |
| ------------------- | ---------- | ------------------------------------------------------------------------------- |
| *Pulse Input* (►)   | **Pulse**  | A standard **Input Pulse**, to trigger the execution of the **Node**.           |
| `Bluetooth Address` | **String** | The unique *Bluetooth* identifier that is associated with a *Bluetooth* device. |

## Outputs

| Output              | Type       | Description                                                                                                                            |
| ------------------- | ---------- | -------------------------------------------------------------------------------------------------------------------------------------- |
| *Pulse Output* (►)  | **Pulse**  | A standard **Output Pulse**, to move onto the next **Node** along the **Logic Branch**, once this **Node** has finished its execution. |
| `On Finish`(►)      | **Pulse**  | An **Event Pulse** which is triggered if pairing has finished.                                                                         |
| `Is Paired`         | **Bool**   | Returns *true* if the device is paired and *false* if not.                                                                             |
| `Bluetooth Address` | **String** | The **Bluetooth** address of the device.                                                                                               |
| `On Error`(►)       | **Pulse**  | An **Event Pulse** that fires in the event of an error.                                                                                |
| `Error Message`     | **String** | The error message in the event of an error.                                                                                            |
| `Bluetooth Address` | **String** | The *Bluetooth* address associated with the error.                                                                                     |
