Hi DJI Forum Community!
New Mavic Pro owner here
I have about 20 or so flights logged so far on the Mavic Pro. I had a disconcerting experience today and am looking for some feedback from the community and or DJI forum staff.
I was flying my mavic today in 35 degree (farenheit) weather (within min operating temps so i don't think this had anything to do with it and the battery was installed from 70 degree room temp charging area inside).
I set up waypoints (while in the waypoint intelligent flight mode) throughout our property today. Five total waypoints, all entered and uploaded as a mission successfully. I flew this mission successfully and then it automatically exited the waypoint intelligent flight mode and I manually flew 'home' and landed - no problem. I then loaded another battery in and flew manually to the first point of the waypoint mission i had previously configured, and wanted to fly this mission in free orientation mode, to get some different angles of the property.
Upon arriving at waypoint '1' and loading the waypoint intelligent flight mode and applied my aforementioned mission, the mavic seemingly started to gain altitude (slowly) - I was going to fly this mission at around 250 feet. And then suddenly the app announced, 'landing initiated'...what is landing initiated mode, I am aware of RTH, but not aware of a landing mode? this was different than RTH and healthy drones seems to interpret the logs of 'landing' and 'return to home differently', so they are seemingly two different modes...battery was still at 95+%. I exited landing mode by canceling this in the DJI Go 4 App. I then tried to start the waypoint mission again, and same thing happened, inadverdently landing mode was initiated...I actually recall only hearing the app anounce 'landing', and the craft beginning to descend...this would have been a bad situation had it actually tried to land as 1. the mavic was above a forested area, and 2. OA was logged as disabled as you can see below...
Here is a snippet from healthydrones log analysis that displays these logged landing mode events (event E and event H below):

After cancelling the two RTH/landing attempts, i cruised around a bit and then was able to apply the waypoint mission which it flew as expected in free orientation mode.
Here is a log snippet when I had actively enagaged RTH from another flight:
c | 15m 00s | 297.2 ft | 8 ft | Tip | [url=]Tips__Return-to-Home Initiated[/url] |
I am rather concerned about these two incidents...has anyone ever experienced this or have any feedback?
I am going to post the following error in a new thread: "[url=]Warning:Altitude Limited Mode Entered"[/url]
Any other data I can provide to help determine what's going on? I do have DJI Care Refresh for this mavic and can send in, but purchased my Mavic to take to Tahoe with me next week. Really hoping it's in some reliable state for the video and image capturing tasks I had planned.
thanks!
