I have recently updated my CUAV V5+ Autopilot to FW version 1.12.3 and I have noticed that motors can be armed even though the safety switch (on the NEO V2 GPS module) has never been pressed.
I have triple-checked the parameters, read several times the instructions here but no matter how I change the settings, it is always possible to arm the motors, even if the safety button has never been pressed since power on.
I also noticed that if I keep the safety button pressed nothing happens but if I push it three times it makes a confirmation sound. The pre-arm behaviour doesn’t change but it tells me that the button is physically connected.
Could you kindly help me understand what’s happening?
