Motor test

[luisaugustos]

Hello everyone!

I'm Luis and I'm researching some topics about drone noise and signal processing.
Someone know how I can test independent each motor of DJI, I mean probe each motor in different percentages to record the produced sound? Like the ESC calibration that has in DJI Assistant.

I have a Mavic Air and an M300 for these tests.

Either you sniff assistant communication or use the wireshark protocoll here: (it's not complete)

Easiest done from a VCOM connected to drone usb.
Can be done from app, but _much_ harder.

There might be another way I'm not aware off, but I doubt it.
