Aux Function
The Aux function command is used to trigger auxiliary function on ArduPilot vehicles. The available functions can be found in the ArduPilot documentation. Note that a function may not be supported by all vehicle types. Even if a function is supported by your vehicle it may not be supported by this action. For example, functions designed for continuous values, such as "flap" on ArduPlane will not work.
There is also the option for custom display text. If none is provided default text is generated based on the selected options.
TIP
If there is a dedicated command available it is better to use it. This maybe via one of the built in actions or the command or custom command action.
