I have been struggling with getting meaningful warnings about low battery. Thus, I have installed a small panel with 3 LEDs; one for arming connected to pin A7, one for GPS connected to A6 and the third for low battery connected to A5 (I wanted to use a LED instead of a beeper).
In MP, I set the LED_MODE to 11 and turned on the Battery failsafe with action to land. (see pictures).
When testing this a few days back, I kept the hex at a low altitude (to avoid fatal crashes). I have also installed a FrSky battery monitor so I can see the voltage on the radio.
When I was getting close to the low voltage alarm I had set on the FrSky, I suddenly saw the arm led on the hex blinking. Probably because I had reached the low voltage set in MP. After a split second, the hex leaned over about 45 degrees and crashed into some chairs. Fortunately only some propellers and the GPS pole was damaged.
If someone could provide some help on the 2 issues below, I would be very grateful.
- I have tried to analyse the log, but I have to little knowledge about it. I can see in line 2908 that I get ERR 6 and that MODE is set to Land in line 2907 (the line before ??).
But why does the hex lean over and crash?
I have attached the log below. Any help on looking at it would be very much appreciated.
- Regarding the low voltage alarm, I would just want to get an alarm at a specified voltage so I can land manually. And why does not the LED connected to A5 light up when I reach the limit?
