    Has anyone managed to view logs from the Mavic? I've managed to extract the .DAT files from the Mavic but the usual methods of converting them to .CSV etc. don't appear to work.

    DatCon throws up an error saying the .DAT file isn't a .DAT file...:(

    Has DJI changed the format again...??

    I don't know of any tools that can read the DAT flight logs. There are tools available for reading the TXT flight logs though. See my list here.

    DatCon cannot convert Mavic DAT flight logs.

    Just heard that DatCon is being worked on to work with the Mavic...

    I'd like to have a play with the tools, but I don't have any suitable .DAT files.
    Does anyone have a small sample file from a Phantom I could look at...??

    Here is one of the smallest I have. It does not include the vision data.

    How do i access the flight logs? I try to access the Flight record list in Assistant 2 software but the icon is just spinning and nothing happens, have waited for like 7 minutes, also tried the Data Export but same thing there.

    How long should it take to access those files?
    Is there any other way to do it?

    Seems this is a common problem using the DJI Assistant 2 to retrieve the .DAT. Some people have succeeded by 1) restarting DJI Assistant 2, 2) using a different USB cable, and 3) by using a PC if they are using a Mac.

    Yes I'm using a mac, and haven't tested with another USB cable, but that has almost never helped me to exchange the USB cable in any situation.
    But i will try a PC and see if that goes better?

    But is there some other way of accessing the log files? Is the Log files in itunes for the GO 4.0 app the same logs as in the Assistant 2 software?
    Since i found some .DAT files there as well as some .TXT files. But the folder called only "logs" contained no usable information for me in its .TXT files.

    No.

    No. DAT flight logs are stored on the Mavic. TXT flight logs are stored on your mobile device. You'll find a lot more data in the DAT flight log. And, unlike the TXT flight log, the DAT flight log does not stop logging if the downlink disconnects.

    The .dat file on the tablet is not the same as the .DAT on the Mavic.

    The mobile device running DJI GO 4 allows you to export the csv file but where does it go? I'm running an iOS device.

    I did do a form search and this seemed to be the best thread to ask the question in.
