I'd like to check in to see if anybody else has had similar problems to me with their MPs or MPPs. This problem has been quite a scary one for me, my new MPP being my first drone of this calibre. The problems I've faced have resulted in me already having to send off my drone and controller to receive a new set under my warranty, and now I've unfortunately met the same problems again.
My problems began when I was flying my drone several months ago, when I noticed the drone, which had been hovering several metres away, was landing of its own accord. The controller was being unresponsive but appeared to still be connected, while my phone was stating that the aircraft had disconnected. It seemed almost as if the controller had frozen, or hung. Eventually, the controller switched to 'connecting' again and reconnected. However the same thing occured again several minutes later.
A few days later the same thing occured except the drone was about 40ft up, and maybe 20ft away. The controller once again appeared to hang (all info frozen on screen, completely unresponsive) and the aircraft ascended. The controller made no attempt to reconnect and the drone flew to home. The .txt files from my phone, when uploaded to airdata, state there were long periods of data loss when this occured.
I believe I saw in the log for the first time this occured that the controller had seemed to disconnect. However I was much more concerned when, after this last experience, I returned home to check the log out from the drone and noticed that it was simply absent.
I kept flying for a few days hoping the problem would correct itself, it seemed to happen almost randomly. Ultimately I believe the final straw was when the drone disconnected from the controller as it sat on a kitchen floor just a metre away from the controller in the same was as it had several times before. At this point I contacted DJI support and was told to calibrate the IMU, compass and controller. I did all these, and the drone did indeed appear to fly fine once again. However I soon realised that eventually the drone was not recording any logs anymore, for any flights whatsoever, or at least not showing them in DJI Assistant 2. At this point DJI asked me to file a repair case. I sent back the controller and the drone, and both were replaced under warranty.
I went away hoping that after several droneless weeks, all of my problems would disappear when the new one arrived. The new drone did appear to work without issue for a few days, however the problems began again just a few days ago.
Firstly, I took the drone up for a moment inside in the house. All went well, except I hit the props off the end of my bed and damaged two of them. This all seemed fine, and I simply replaced the two props. I noticed that airdata showed two moments of data loss for roughly a second before the crash, however the drone's log, which appeared without problem in DJI Assistant 2, showed no such connection loss from the controller. I assumed that the cable connecting my phone to the controller may have been loose, and accepted that the crash had been my fault.
Here's where the serious issues begin again: I went to take up the drone again in order to see if the 'data loss' recoccured. This is when the 'controller freezing' appeared to start again. I was having issues getting my phone to connect to the controller, and as it tried to load the DJI GO 4 app, it kept failing, and every time it did, the controller froze as before, and ceased to be able to control the drone. This kept happening repetivively over the course of several minutes. It seemed almost identical to the problems I'd faced before except even worse. After this went on for several minutes, I gave up, and connected my drone to my PC to check the logs. The log for the entire time the controller had started acting up was not there in DJI Assistant 2.
So this was annoying to say the least. I believed it may have been my phone or the OTG cable that was the issue (it's a OnePlus 3 running the latest android and DJI Go 4), however there is no way the phone, app or controller should be able to interfere with the flight data recorder on the aircraft that I'm aware of.
The next day I tried to fly it again, ensuring the cable was connected properly (I normally do, as in, just much more so than usual). Despite there being no connection problems, the prop guard got caught in something after the drone veered to the right. I went to grab the DAT file in DJI Assistant 2, and it was not there.
I've reasoned the phone may be the problem, so today I went to fly with an iPad Mini 4 using DJI Go 4. I had no problems, disconnections etc. over the course of two flights. What I did was: fly once for several minutes, land, power cycle the drone, fly again and then land. To the best of my knowledge this should've made two logs, one for each power cycle, appear in DJI Assistant 2, and also two logs appear on the iPad. Some flights have disappeared completely from DJI Assistant since yesterday, while one of today's flights is also missing. They are visible in DJI GO 4. Here is the result, sorry for the messed up order.
I really hope I've made a massive oversight somewhere and that I'm simply missing something obvious, but this has really been on my nerves and it is quite upsetting considering the money I spent on this piece of tech. I feel like missing flight records could result in an inability to make warranty claims, and that seems very dangerous. Thank you so much for all your help, and sorry for the long post!:
