We are sorry to hear you had an incident. The beeping usually means that something happened on-board that necessitated immediate landing. This is usually a battery issue that could either be poor battery calibration or an error.
It seems like it lost connection first and then try to land because there is no descent data in the log. There is nothing in the log file that shows the descent which is usually what we see in this case. It was sending telemetry successfully right up to the last image dot you see in the Flight Detail.
The aircraft was set to return home in the case of an issue but when that beeping happens it is usually something more emergent. The battery was a little hot but it would usually complain first before having something like this happen.
My guess it that it would be somewhere around the end of the blue line.
There is also nothing in the error messages that gave any indication of what was going on.
Sorry, but that is really all we can tell from the log file. Good luck in your search. If you find it DJI might be able to get more information out of it.
