4.6 beta 4 In-Flight FFT-Based Harmonic Notch

I’m on my long way to enable FFT notch setup for my H7 based Copter.
What I understand I should enable FFT then perform a test flight.

In-Flight FFT-Based Harmonic Notch Setup — Copter documentation

I did both but the problem is I can’f find any given data in the logs.
The true is I have to build my own FW so to make it lighter I disabled some modules. Could be I removed FFT as well but it’s I do not think so…

define AP_SCRIPTING_ENABLED 0
define DRONECAN_SERIAL 0
define AP_RANGEFINDER_ENABLED 0

define HAL_SPRAYER_ENABLED 0
define AP_LANDINGGEAR_ENABLED 0
define AP_WINCH_ENABLED 0
define AP_WINCH_DAIWA_ENABLED 0
define AP_WINCH_PWM_ENABLED 0

In short words I’m stacked on FFT_ENABLE,1 , as can’t find:

Any ideas?

Moved a bit with enabling INS_LOG_BAT_MASK

Other FFT methods ask to enable INS_LOG_BAT_MASK
while wiki given above does not (for in-flight FFT…)

And again…

good but save and reload to get others params… and something is misspelled here …

Not clear to me what you are asking here.

It was 2 days ago, before I saw a great video explaining Notch Filters. My knowledge was based on wiki only which is little complicated and confusing.
And yes, that post is a mess. Will delete it in a day.
Last wiki screenshot just shows typos in wiki while INS_LOG_BAT_MASK is not mentioned on FFT filter wiki page at all. That’s why I got some problems.
Sorry for using your time.
