Decrypt any DJI flight log with Flight Reader

[msinger]

Since the release of DJI Fly 1.2.2 and 3rd party applications using DJI SDK 2.4.13, DJI's flight logs are being protected by an encryption scheme that hasn't been shared with most of the developers who created DJI log viewers. That caused most of the commonly used log viewers (like my free online log viewer) to be rendered useless for newer DJI apps and the last several consumer drones released by DJI.

A recent partnership with DJI allowed me access to the DJI API — which several other partners (like Airdata) are using today to decrypt the new flight log format. After a few months of development and testing, I'm happy to announce Flight Reader (my offline log viewer) is now able to process flight logs created by any version of DJI GO, DJI Fly, or other apps using the DJI SDK.

Never heard of Flight Reader? Here are some of its benefits:

• No monthly fee
• Privately process & store your flight logs offline
• View an unlimited number of flight logs
• Customize the logs & reports to best meet your needs

See more details about Flight Reader here.






TLDR: You can use Flight Reader to process and view your encrypted TXT flight logs offline.

Looks very good. Congrats!
Are you going to process other sources in the future such as Pix4Dmapper logs?

Flight Reader is currently able to process flight logs from DJI, Litchi, and Map Pilot. I'm interested in adding other flight log formats suggested by Flight Reader users.

Great post, I had never seen this type of amazing post ever.

Daisy- are you human?

Daisy- are you human?

.. because all humans should already know about this?

More like wondering if a real person could come up with such a strange and inane comment as the one above...
"Great post, I had never seen this type of amazing post ever."

And if I am wrong Daisy, and its just a language issue, my apologies...
