Okay - you asked for it! LOLDon't hold it in....share with us your process on viewing .DAT info on whatever Android app.
This is for Android only - I don't know the workings of the Apple stuff. Connect your Android device to your PC. When the appropriate dialog box appears - it will have an option like "Open device to view files" That opens up for me, with two folders - one for card and one for phone. Open the PHONE folder and look for a DJI folder. Open that and you'll find a folder named "djipilot." In that folder, open the folder named "flightrecord." I've not run the app with a tablet - but it should be reasonably obvious if you have more than one folder - it shouldn't take too much sleuthing to find the appropriate path to the proper folder.
And there you will see all your flight records. They are in folders that make them look like .txt files - but they're not. Hang on.
Keep that folder handy and open your browser. Navigate to www.flylitchi.com. On that web site, you want to navigate to LOGS. Once you do, you'll see an option down on the lower left to convert files to CSV format. Select (or drag and crop, copy and paste) one of your log files from the phone and start the conversion. Now, this could get tricky.
I have Microsoft Office on all my PCs. When the file is converted, Excel automatically opens and the converted file is displayed in Excel. If you don't have Excel on your PC I have no idea where the file goes or what happens next! Sorry!
If you do have Excel, the file opens up and you'll see all these columns of data. Info from that particular flight is gathered every so many milliseconds and each line represents a snapshot of what your Phantom was doing at that specific time. Even rather short flights will have hundreds, maybe thousands of lines.
The above works ONLY for the files found on your phone.
If you stumble across "Enter Flight Data Mode" in the DJI Pilot app, you'll be directed to plug in the appropriate USB cable to the front of your Phantom (that's the USB port hidden under the small flap beneath the logo on the front) and download pilot data. THOSE FILES WILL NOT WORK IN THE PROCESS I DESCRIBE ABOVE. They will generate errors. The files for the process I described MUST come from your Android device - phone/tablet, whatever.
Don't give up yet. There are some people working on a system that should make it easier to read pilot data files. You might be able to find a bit of info at www.flightreplay.com
Now you know everything about the subject that I know. Frankly, there was so much data there. I just went back to reviewing my pilot logs in the appropriate section of the pilot app - on the main screen, select User Center and the center icon provides access to your flight logs.
Good luck - sorry it's so long, but.....
