Comments on blog show that not everyone that has upgraded to the latest firmware has problems like mine:
Compass Error, app disconnect from drone, app crashes, totally garbled video transmission to app, GPS gone while RC shows 16 satellites, flight log does not show warnings, video asctually recorded OK to SD card but flight log shows no video.
The Litchi site says DJI has admitted to a bug in their latest firmware that also affects the performance of the Litchi app. But now I continue to have problems even though I have gone back to 03.0400. So either the firmware change was not complete, or there are more problems than just firmware.
The fact that other people have no problems can be for one or more of several reasons.
1. I ordered my Mavic the first day pre-ordering started. It is reasonable to assume my electronics is not the same as units delivered since December. So there could be an electronics change that requires a recall and new electronics for compatibility with newer software before my problem will ever be resolved.
2. The software/firmware has to be very complex, working for very different products from one app. Could there be function calls in a particular order that set off a chain of events that cascades to an unstable condition – maybe creating random timing problems in communication between components. They need to develop an app for each drone model.
3. The mobile device used as the monitor could have some form of incompatibility, but a USB connection simply transferring data has well established protocols and as long as the device has recent Android system, enough memory and processor speed that is unlikely. On the other hand DJI has a very short list of tested compatible devices, and my Samsung Galaxy Tab S is not on it. Neither is my LG phone. I have seen my RC showing 16 strong satellites while the app tells me GPS was lost on the monitor? Is the AC lying to the RC or is the RC lying to the app?
4. Maybe the firmware installations are not performing correctly. When I went back to 03.0400 the download went to 100% and the data transfer to the RC and AC started but never went beyond 99% for 45 minutes. The RC went from UPGRADING to READY TO GO, but the app never showed complete. The firmware window shows the current firmware version only when connected to the internet. With no connection the app shows a
Phantom 4, not a Mavic. So is the app reading what is loaded in my devices or what has been sent from DJI most recently?
The information supplied by DJI on the operation of this very complex Unmanned Aerial System is minimal and not very well presented. I just learned about the firmware window you can bring up by pressing for several seconds on the three lines at the top right of the GO4 app yesterday – by reading about it on the Mavic Pilots Blog!
The bottom line is that my Mavic Pro has been unusable for commercial work for two months now. I would never subject myself to possible humiliation in front of a paying client with a piece of equipment that malfunctions every time I use it. I am losing opportunity and money every day this continues.
I think DJI is not going to do anything about this as long as they can keep selling these things as fast as they can make them, leaving us initial buyers in the dust. Anybody know a lawyer willing to help the hundreds or thousands of us in this situation?
