Other than be fascinated with the detail of the data, I'm not sure how they could be utilized to produce more info than you get in the summary logs in the pilot app.Īhhh! Patience Grasshopper!. I think this flylitchi data was originally designed to be used with the Phantom 2 Vision+ to create autonomous flight plans. No course data (like a line on a map) is displayed, but geographical coordinates are displayed in two of the fields (one for lat and one for long). The data more or less matches what I see in my Pilot Log data available through the Pilot App, but with details given every so many fractions of a second. There's about a dozen or so different items that are displayed. My most recent flight of just under 6 minutes displays about 2,000 lines of data. When the download is complete, click on it and it should open Excel, with the contents of the file displayed. txt files from the pilot logs on your mobile device and press CONVERT to CSV.Īs long as the file is not corrupted, you'll get a download to your PC (I'm using WIN 7 - don't know what happens on a MAC). In the lower left-hand corner you'll see a small dialog box asking for the file. Leaving that screen available, open your browser and navigate to - then choose LOGS. In that folder, you will find the pilot log folder which contains the flight records for your craft. Look for the DJI folder (it might say DJI Files). A dialog box should open up that will allow you to see the files on your phone/mobile device. I just connect the appropriate charging/data cable from the S5 to my PC. In my case I'm using a Galaxy S5, so it's very straightforward. He instructed me as follows.Ĭonnect your mobile device to your PC. He said we could not use the data files that are derived from that USB port - they will have errors, i.e., corrupted in some way. The day before yesterday I exchanged emails with the owner of the flyitchi web site. The USB port on the gimbal is used to either read data/media from the SD card or for updating, if necessary. The USB port in question is the one on the front of the craft, NOT the one on the gimbal. Once in that mode and pressed OK, I was instructed to connect the USB port to the PC. Like many before me, I used the DJI Pilot App to get into Flight Data Mode. That's fine, but surely there must be some hobbyists who are working on this?!?!? I realize that many people who read this have their own "proprietary" reasons for wanting to crack the code, as they're hoping to profit from sellable applications. It seems to any true encryption algorithm would render the entire file looking like random numbers, with no runs of patterns (unless different blocks were encrypted separately, like a form of EBD coding.)īeing able to read the *.DAT files directly and extract information would be much preferable to the *.txt log files which the DJI Pilot application produces and reads, because the *.DAT files would be written to the phantom even when there's no radio link (like when using ground station) or when radio link is buggy, or when you want to use third party controller applications, and skip DJI-Pilot directly. up to 255, then back to zero, 1, 2, 3, 4. If you look at the binary data, it's definitely broken down into visible chunks of data, and very frequently it has "runs" of a repeating byte, and that repeating byte counts up slowly, 1, 2, 3, 4. They contain enough ascii at the beginning, and have enough pattern throughout them to know that's not the case. There is a rumor going around that these *.DAT files are encrypted, but I'm pretty sure they are not. But it would really be nice if you can get the original log data, which is recorded onto the Phantom memory while actually flying, regardless of radio reception, and read from these. Of course, we have the flylitchi online web-based java converter, which will take the *.txt log files, made by the DJI Pilot application, and turn it into a CSV file, for use with dashboard, and of course you can use the "User Center" in the DJI Pilot application to read some of the data from the Flight Log Files, and display it. Is anyone making any progress with decoding/interpreting the Phantom 3 Flight Log files, in the *.DAT files?
