# Unpair Bluetooth Device

## Overview

![The Unpair Bluetooth Device Node.](/files/NjgTXXWXxtnPGBfUW59z)

**Unpair Bluetooth Device** attempts to unpair a given *Bluetooth* device that may have been previously discovered by the [**Scan For Bluetooth Devices Node**](/incari-studio/toolbox/communication/bluetooth/scanforbluetoothdevices.md). A more detailed explanation of this process can be found [here](/incari-studio/toolbox/communication/bluetooth.md#bluetooth-guideline).

The **Node** only schedules the unpairing process and then returns immediately. This means that it is possible to trigger the **Node** multiple times with different inputs, resulting in consecutive unpairing 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**, **Unpair Bluetooth Device** 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.

It is important to note that while the **Unpair Bluetooth Device** disconnects from a **Bluetooth** device (like a phone), it will not finish unpairing when the **Node** is executed. This will lead to the **Logic** attached to its **Output Pulse** not to work even though there is technically nothing wrong. In order to avoid this, it is necessary to use the [**On Bluetooth Device Unpaired Node**](/incari-studio/toolbox/communication/bluetooth/events/onbluetoothdevicepaired.md) instead. This way, the **Logic** will only execute once the **Bluetooth** device has definitely been unpaired from.

Again, the user must first use the **Unpair Bluetooth Device Node** to unpair from a device. Separately, the **On Bluetooth Device Unpaired Node** can be used to execute the desired **Communication Logic**.

## 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. This can be discovered by the [**Scan For Bluetooth Devices Node**](/incari-studio/toolbox/communication/bluetooth/scanforbluetoothdevices.md). |

## 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 Error`(►)       | **Pulse**  | An **Event Pulse** that fires in the event of an error, namely that unpairing failed.                                                  |
| `Error Message`     | **String** | The error message in the event of an error.                                                                                            |
| `Bluetooth Address` | **String** | The *Bluetooth* address of the device for which the pairing failed, in the event of an error                                           |
