Just upgraded my DJI Go App on my iPad Mini 4, I have noticed there is an option for ESC BEEP, under advance copter settings. When I activate it my copter emited a loud beeping sound from what I think the ESC boards. What it is, and what does it do?  Edit: I can't find any information regrading it in the P4P manual or on this board.

I noted this as well. My assumption is that it may be handy in case of a crash in tall crops - if the electronics are still working.

...or even in thick woods.  Good point.

It also might be useful when you're trying to diagnose whether it's your motor or your ESC that's not working.

OK, thanks for the information. It must be new as I have found no documentation regarding this new option.
