Thanks for the link. Wow, that thread has everything: conflict, animosity, comradery, honor, dishonor, not to mention some really good information.
"that thread has everything"
Doesn't it though?
It was interesting because there are some really, really, really smart people on that forum. Several of those guys are experts at deciphering the flight log contents. A couple of them are the go-to resource for predicting where to find lost drones. Sadly the flight log on your control device ends recording once the drone goes out of range and the telemtry signal is lost. But, based on battery time remaining, last known position before signal is lost, ground speed while drifting away, altitude and time it takes to descend from there once the battery is depleted, and several other factors and clever assumptions, these guys can estimate with surprising accuracy where the drone will eventually have come down to earth, often many kilometres away from the last known position.
They were convinced that the hidden files found on the Mini's microSD card couldn't possibly be an onboard recorded flight log, because DJI has never done it that way before. DJI has typically used a separate inaccessible encrypted recording on another chip cemented inside the drone. But, because the weight of the Mini is stripped down to a bare minimum, those log files are now instead recorded onto the removable microSD card, the same one on which your photos and videos are recorded. Those log files are accessible, and they contain far more information than the log files transmitted via telemetry to your control device. "a treasure trove of flight data" The experts are still working on figuring out what it all means...
