During my last 4 flights with my new
P4P (only 2hrs flying time) the ATTI mode would switch back to GPS mode without any reason/warning. This didn't happen with the flights before these.
The ATTI mode was selected using the switch on the controller. However the mode would change to GPS and reflect on the iPad screen in DJI Go 4. I changed the mode to GPS and then back to ATTI using the controller switch, but shortly afterwards the mode would switch back to GPS again.
I have been through the flight logs and there are no warnings or messages indicating the reason for this. Please help!
I've had a similar thing happen with my
P4P+. In my situation, I experienced switches from P Mode (GPS Mode) to Atti, while the switch on the controller was set to P Mode. The switches were apparently random. Also, when I was flying normally in P Mode, I could switch between all flight modes with the aircraft responding as expected.
Definitely post the flight logs so they can be reviewed. Some of the mode switches on my aircraft were so fast, they weren't reported on the controller, but showed in the logs. The general consensus from those here after flight log reviews was a hardware or connection problem with the GPS module and/or main control board.
Accordingly, I started the warranty process with DJI. However, before I sent the aircraft in to them, it was suggested I re-calibrate the compass in a different location, and then fly to see if the switches happened again. DJI's position was that if the compass experienced magnetic interference from steel objects close by my launching point, the communication between the compass and GPS or other flight controls could go wonky. I know this has indeed caused problems with other pilots, even resulting in crashes, but I'd not ever heard of it causing modes to switch. And, I didn't understand how this would resolve anything if the problem is hardware based.
Still, I tried the re-calibration in a large, grassy, and open field, with the closest metal hundreds of yards/meters away. I couldn't get the calibration menu to open, (I was in the wrong area of the app), but I flew anyway with no apparent issues. I've since flown nearly a dozen flights, well away from any known metal objects/structures, and have not experienced any unauthorized mode switches. (At least, none I'm aware of - I've not checked the logs.) DJI has said if the problem surfaces again, I am to send it in.
Needless to say, I was curious about DJI's theory. I've since found out that the concrete pad where I launched from the first time my switching problem happened is indeed steel reinforced. As it was fairly small, perhaps 60ft/20m square, I had thought it was built around wood forms. Time will tell if the issue with my
P4P is resolved, or simply coincidental. It's a curiosity, for sure.
