Yesterday I flew a litchi mission that was 9 mins long to see what it was like and it worked perfectly. Today I was playing in the garden with the mavic not going above 3 metres and about 10 meters away from me I had 14 sats locked and the nearest obstacle was about 8 meters away but there was a annoying beep ever 4-5 seconds from my phone. Nothing was displayed on the screen and the mavic behaved perfectly.
This beeping hasn’t happened before and it put the shits up me thinking something was wrong. Does anybody know what it could mean? The other thing is when flying yesterday I tried the rth in litchi and eventhough my rth height is set at 30m it was nowhere near 30m, more like 10. I finished the last waypoint at 10m height about 15m away from the home point and when I pressed rth it just flew straight to above the landing pad and started to descend. If I done that in GO4 app it would have shot up to 30m then came home.
