Mavic Pro 2 - Read dat files

[wshuart]

Anyone know what software will open/read/convert DAT files from the actual drone?

Welcome to the forum. This what you are looking for ?

I'm actually trying to get at the aircraft data. I'm not sure the app is good enough... unless it records 30hz data?

The Mavic Air and Mavic 2 DAT files are only decryptable by DJI.

Thanks. Does anyone know if any of the flight apps (Go, litchi,etc) record/log data at 30hz?

Although the DAT file on the AC is encrypted, the one on the mobile is not.

However if your concern is about AC/RC disconnects, local DAT isn't as useful.

I am looking to get access to as much telemetry and system data as possible and as frequently as possible. That’s my concern is on the controller/app side, what is the refresh rate? 1x per second?
Ideally I’d like to get 30x per second data

Is there an app or a way to do that with a Mavic 2 pro - or maybe even a phantom 4 pro v2?

The SDK only allows 10 Hz data as far as I am aware, so no.

You can use DatCon to convert the P4PV2 .DAT. DatCon can be obtained here
DatCon Introduction

Not all the telemetry is as fast or faster than 30 Hz. To see the sample rates take a look at
V3 .CSV column descriptions

Bud, I was able to yank the dat file from the P4Pv2 and run it through your program and I see it is 30hz (which is great). Does it also show the camera gimbal attitude? In degrees or something? Did I miss that?

Sorry, no gimbal info In the.DAT. AFAIK, the .txt is the only place where gimbal data exists.

DatCon reports at whatever data rate you request, independent of the recording rate. Some of the DAT file data are logged at 10 Hz (e.g. GPS) while other data are logged at up to 200 Hz (e.g. rate gyros, accelerometers). So it depends which data you are looking for.

 

[wshuart]

I’m looking to get:
time, GPS (x, y, z), rotation, speed, gimbal elevation (degree or something) to insert into movies (exif) obtained by the drone (camera/sensors/etc). Ideally, if this was 30hz to match to a 30 fps movie, that would be the ideal solution...

That explains a lot - I was wondering why, in other threads, no-one had posted info from the attached dat file for a Mavic 2, and I couldnt even open it using Datcon...

 

[DanMan32]

There's no reason for them to do that. There are ways to allow visibility but detect tampering.

 

[Gripps]

This may have been covered already, (sorry), but can all the flight data be erased from the AC?

 

[Kilrah]

No.
