Process DAT files

[SebastianViollaz]

Im working in an app that involves UAV inspections. Currently its working for Ardupilot controllers but i also want to make it work with DJI UAVs. To acomplish this i need to be able to see the flight telemetry of a flight so i can process it in my app. I have made a flight and searched in de UAV´s SD the log files but the folder where it supose to store data is empty. I have dowload DJ Assistan 2 where i have been able to dowload a DAT file that it´s suposed to store the data i need. But Im unnable to see the data. I tried using DatCon and this page: DJI Flight Log Viewer | Phantom Help . In both cases i´m unable to read data. Is there a way to acces and read crud telemetry data extracting it from the UAV?.

I read that it´s possible to dowlaod from the GroundStation App. But this is inconvinient for me beacuse if i decide to fly the UAV only with the controller i could´t be able to get tha needed data.

Their "pro" verison might help

DJI drone flight log viewer | Flight Reader

Quickly view and analyze your DJI drone flight logs offline from your Windows computer

But AFAIK it's still based on the app logs. Aircraft logs are encrypted.

Flight Reader and my free log viewer (above) are only able to read unencrypted or encrypted TXT flight logs.

If DatCon cannot read the DAT flight logs, then they probably cannot be read. @BudWalker would know better than me though.

Regarding using DatCon/CsvView to process a .DAT log file. It depends on which DJI platform you're interested in. The more recent platforms will have encrypted .DAT log files and can't be processed by DatCon/CsvView. AFAIK these platforms and before will have non-encrypted (i.e. useable) .DATs
1) Mavic Air 2
2) Mavic 2
3) Mavic Mini 3
4) FPV
5) Avata
6) Phantom
7) Phantom 4

Also note, that for many of the platforms a useable .DAT can not be found on the drone itself. Useable .DATs will be found on the device running the Fly or Go app.
