I’ve got an IRIS+ running 3.2.1. The phone I’m using is a Sony Xperia Z running Android 4.3. I’ve created a mission in Tower, connected to the IRIS, set waypoints (altitude and duration), and then uploaded the mission to the IRIS.
When I then push the “arm” button, I get the following message:
ARM: Throttle below failsafe
I’ve searched on that error message and get nothing. Any thoughts/suggestions?
