So I've had my P3P for all of a week. Crashed it in my pond on day 2 - yet it recovered fine after 2 days of drying out.
I am by no means well versed in the world of Phantoms. Maybe my step-by-step will help the next guy.
I keep the little 16gig card that came with the drone just for firmware.
When a new firmware comes out the old one goes to a folder along with the log. That way I have the old one, but its not on the root of the card to cause confusion.
I first read the previous posts about updating so I had a clear idea of what to expect and do.
To be clear:
The DJI Go app has a version: 2.72 for Android
The firmware you download 1.08.0080 is "all in one" meaning it is the same firmware file for both the drone and the controller.
I tried
updating the controller first using the firmware on a USB card adapter as in the video - and nothing happened. It acted like there was no firmware .bin file on the card.
So I got thinking that maybe the controller is looking for the log file generated by updating the drone. Maybe the remote won't update until it knows the drone has.
I updated the drone. No problem
At 9:30 I watched the camera gimbal do a much of maneuvers (calibration?)
At 10:01 the drone started flashing its 'happy lights' pattern and the camera LED went steady-green indicating it was done and successful.
Removed the sd card from the drone and put it in the adapter to plug into the controller.
Plugged in the card adapter - started my stopwatch. The update is supposed to start at around 60 seconds.
After 2:30 nothing happened. So I played the video again. At 2:00 into the video the guy mentions "The documentation led me to beleive I needed to have the Phantom on, but in actuality I did not". What documenation he's talking about I have no idea because the firmware download doesn't come with so much as a Readme.txt.
At 5:00 the remote started beeping - probably becuase its powered on and disconnected for so long.
Powered down the controller and removed the card adapter.
Connected my Samsung Tab4 to the conntroller (all powered off)
Powered up the drone
Powered on the tablet
Powered on the controller
Control info panel reports that the firmware needs to be updated and provides a link to download it directory from the tablet/DJI Go app
After download complete it offers to install the update to the controller.
That was successful in 60 seconds.
Drone still did not connect to the controller - but I'm not surprised.
Powered everything off again.
Power on drone - let it finish booting
Power on tablet
Power on controller (launching DJI go automatically)
Coonected to aircrafted
Go fly through a full battery.
Maybe this is normal, but even with 12-14 satellites connected the drone will still drift by 3-6 feet horizontally and 1-2 feet vertically.
Once I have a charged battery again and some free time I'll go through and re-calibrate compass on controller and tablet again.
