I just downloaded v3.8.2 today (build 381) will try it out as soon as I can. My drone is Mavic Pro, firmware is up to date, Android 7.1.2. I didn’t check the card to see whether it was still taking shots during failsafe RTH, I had to force quit Pix4D once the drone landed, just kept making the shutter sound even after powering the drone off. Photos were taken during the mission up to failsafe. I was not aware that DJI GO has ANY interaction with Pix4D re: setting the low battery RTH threshold level, since you must Force Stop in Apps if it was previously used to get Pix4D to work.
So my workflow should be (correct me if I am in error):
Power drone on
Power remote controller on
Open/connect to DJI Go4 - should I leave Smart RTH Enabled/Disabled?
Set low battery warning slider below 20%, close DJI Go4
Force Stop DJI Go4 in my Apps (no defaults set)
Start Pix4D Capture, allow once, plan a mission requiring more than 1 battery life
Manually take control with sticks at some safe point below 20% battery level and fly Home
Is the Abort in Pix4D done automatically when manual override via stick control is sensed? Or do I switch from P to Sport mode? (clarify)
Leave Pix4D running (?) power off drone battery, leave RC powered on, swap fully charged battery to continue, power drone back on
Wait for Pix4D, what happens when drone restarts? Will the app know it has restarted and is ready to continue?
It seems to be a very complex process and must be done exactly or it will fail, wasting a LOT of time, batteries and very frustrating sometimes just to do simple things. Let me know if I am understanding what to do correctly, thank you!
