**On MAVLink Stop**is an **Event Listener Node** allowing the user to trigger a **Logic Branch** once a connection to an **MAVLink** serial port has been terminated.

**MAVLink 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 **On MAVLink Stop** will not show up in the [**Toolbox**](https://docs.incari.com/incari-studio/2023.1/toolbox/overview). Please refer to the [**Plugins Editor**](https://docs.incari.com/incari-studio/2023.1/modules/plugins) to find out more information.

[**Scope**](https://github.com/cgi-studio-gmbh/incari-doc/blob/2023.1/toolbox/communication/overview.md#scopes): **Project**, **Scene**.
