Flight data...

Hi,

It's time to go further in the Mini2 learning curve.. How and where can I access Flight data and telemetri with... DJI Assistance 2?

Are you asking about accessing data on the drone, or in the App on the phone or both?

Hi Pillius,, well whats the difference? I wanna see where I have been flying and telemetry.

I suspect that only encrytpted DAT files exist on or in the drone and that, with regards to logs, the Assistant 2 is meant to access the drone rather that the App. If the DAT files on the drone are encrypted then it it likely that ONLY DJI can read them. You can likely store them on the computer, via the assistant, (as you can with the Mavic Mini) but that is likely about all you can do with the assistant with regards to logs.

If you are talking about logs on the phone, then normally the assistant is not needed to access those logs. An 'unaided' USB connection from the phone to a computer is all that is required. Also there are probably two sorts of logs on the phone, DAT's and txt's.
From posts on here I think DJI started encrypting the phone DAT's when they launched the Mini 2, the .txt's are apparently readable by the software CsvView.

Given the change to encrypted DAT's on the phone I supposed it might be worth having a look to see if DJI have removed the encryption on the drone's DAT's but I wouldn't gamble on that having happened

Are they really encrypted, or just encoded differently that nobody has been able to decode yet?

If the answer to your seemingly pedantic semantic challenge might be "no" where does that get anyone?

The reality is the .dat files are written in such a manner that they can't be subject to any meaningful interpretation by third parties.

It might be DJI's principal intent is to prevent manipulation of the encoded data by third parties rather than protect the content from read access (motivations and benefits here should be obvious).

In any case- for the purpose of this discussion the files are encrypted.

I can tell you how to access flights history: Inside DJI Fly, go to profile, then press "More"
Hope this helps

WOW!!! Just found the video of the data on the map / satellite - this is awesome. How can I now download this video to my laptop?

If you're talking about the flight log playback, you can retrieve the TXT flight log for use with log analysis but the video representation you can't.

ok, then its a new Q: Where to find the TXT flight log?

So some sort of iphone screen recorder is the only option, I guess?

DanMan32 · Dec 25, 2020

That's the easiest way. There is an app out there that will emulate pilot view but a bit pricey IMO.

Telemetry Overlay and more data tools

Hi! For the last 3-4 years I've been working and experimenting with the GPS and other sensor data in DJI drones and action cameras. All the learnings have now materialised in this standalone app for creating telemetry overlays on videos: Some of the previous utilities I have released (some...

From the link you posted under 2. LOG FILE TYPES- Aircraft DAT files "Unfortunately, on recent DJI models (Mavic Air, Mavic 2, Mavic Mini and Mavic Air 2) the decryption keys are hidden, and so those are not readable except by DJI."....

It is likely one area of speculation of arguable triviality can be put to bed- the existence of "encryption keys" suggests the .DAT files subject of your comments are in fact encrypted (even in strict accordance with your narrow definition).
