I've had recurring problems with corrupted Home Point assignments upon innvocation of MC > Home Point Me. See http://www.phantomhelp.com/LogViewer/ZHC5WAKRUS6VUZ4IGPT9/# Note the Home Distance increase to 12,199 meters after the attempt to reset the HP Me to local environsOr, http://app.airdata.com/main?share=KXnGqD (more accurate map)
Instead of recording the new HP at the RC/Mobile device location, it updated the HP to a previous HP, 12,199 m away, confirmed to have been used in another flight two days prior, and the AC started off automatically to this location after issuing the warning "The remaining battery is only enough for RTH." Then other warnings "Braking to avoid obstacle", when there were none. I caught it in the nick by pressing the abort button on the RC.
This after making sure the launch home point was properly recorded. According to the screen message at the Home Pont: Me location, the new attempted location was 124 feet from the launch home point, not 12,199 meters. All this noted on the above link.
I deactivate DJI Go 4 after every use, assuming left-over remnant data that might corrupt the next flight. This was a fresh, new start for the day. Subsequent flight experiments worked OK, although, here were "Wait: updating the IMU" warnings.
Don't know if the errant HP is stored in the Go app, or the Flight Controller or the RC. with the lack of an architectural overview, it's been a guessing game as to where the errant Home Point sits from one flight to the next. This is the closest posting that addresses the issue: https://forum.dji.com/thread-84083-1-1.html
This is the second run-away flight resulting from the same bug. Again, fresh start for the day. See http://app.airdata.com/main?share=zAzpmO and http://www.phantomhelp.com/LogViewer/3QUT0J2FY1OJY9N6KYBY/ Again, note the Home Distance increase to 1,368.3ft after the attempt to reset the HP: Me at around 75 ft from the launch HP, 4m 37s into the flight. Same stale HP used in a previous flight near my home two or three days prior.
Running DJI Go 4, v. 4.1.5 (updated to 4.1.9), DJI Mavic FW: v. 01.03.1000, iOS: 10.3.3 iPad Mini 4 wifi-cell with AT&T data SIM.
All data synched with DJI cloud.
Note that it has been extremely frustrating to extract DAT data from the flight controller with the latest DJI Assistant 2 with FW 01.03.1000. See https://forum.dji.com/thread-112284-1-1.html . I've exported the "Black Box" to my computer, but not much there.
