Hmm it says it can't read that file. Did you follow the steps in the link on how to export the file? It usually has a name with the date in it and says assistant etc.
P4P Loss of GPS poll.
- Thread starter Tomas Wangen
- Start date
Yes, downloaded the folder and in it there were a lots of .txt files (DJIFlightRecord_2017-01-02_[13-37-52].txt) and corresponding .dat files (fly0xx.dat)? Any suggestions?
I'm not sure. You should only select the flight log file with the date that corresponds to the flight in question. Then hit save to file. It should create one .DAT file per step 5.

Not able to see vote button on iPad. That said I've just bought my p4p and its happened a couple of times already. I thought it might be the software / phone but I then upgraded to iPad mini 4 and it still happens.

I see we have now 10 instances of gps loss (once of more) which I would say is considerable. For those not able to vote, note that this only works in your browser and not in app on tablet or phone.
Lost GPS again today. After having a full 14 Satellites. Here is a screen shot. It was not in sight so used the video feed to bring her home. Just missed a few poles and buildings as it was drifting with the wind at quite a rate! I landed reconnected and was able to fly with GPS for awhile.

Something to mention, not sure if this crosses over from the mavic. But, basically, they discovered that when flying at higher speeds, there is enough electronic noise generated by the motor that is causes interference with the rear (primary) compass. This noise causes the flight controller in the mavic to get confused about what it's being told, and as a safety measure it drops into ATTI mode even when there are full GPS satellites, and you get a GPS error on the controller.
Makes me wonder if this is the same thing happening on the P4P. The mavic DJI knows now and is fixing.

That doesn't sound safe. I had a GPS error on my P4P and they replaced the module. I had the same problems as above. Send it back for warranty. Don't take a chance on flight. Almost lost mine.

My blow away really has me on edge now. It's totally changed my flight behaviour to assume that it could happen any flight. The plus side is that it's making me a much better flyer and being in tune with wind influences etc. You really don't want this to happen upstream of a structure. Last night when practicing loss of GPS, the P4P was going from stand still to 25km/h in seconds after dropping into Atti mode. Not much time to realise what's happening and take over (especially if the brain is working on a task like taking photos).
So I had to upgrade my vote as this happened again. Rather scary as I was just having a very quick session in moderate+ wind and little clearance, and was looking for a good spot for a panorama. At 43 meters (in the woods about 25 meters above the trees) I found myself with no gps, dropping from 17 satellites with no visible interference (and all bars filled).
As I was standing on a path with limited sight (about 6-7 meters side-to-side with trees cutting the sight on both sides) getting caught by the wind was rather nerve-wrecking. I lowered the drone to just above the trees trying to minimize the wind-drift and was off by some 23 meters when it regained reception 20 seconds later. I am certainly not happy with this recurring error and would consider vlos a absolute must for now.
One thing is for sure, I need to improve my atti skills in case this happens again.
At the very least, I got this one just before I lost control (I cancelled the panorama this time).

There seems to be a inconsistency between the displayed sats and the actual reception, which often confuses the software and disengage the P mode, im surprised we have only seen one fw update so far this year...
Dang that's scary man! Hoping for an update to address a couple of things sounds like. Nice shot btw.

Send it back. I've had mine back for a while (or rather a replacement) and have had 0 issues knock on wood!
