In the stock firmware, there seems to be no functionality assigned for the AUX button. However, the button is live and its channel data gets transmitted to the drone on channel 12. It's there, waiting to be used for something... ;-)
@SlientR9 clarified his statement for us, in post 38. He isn’t talking about the black button on the top right quadrant of the ST16.
Our AUX button is still safe from any purpose. Until you figure out something for us to use!
