Hi all,
I have been following Chris Rosser's BF 4.3 Tuning Guide, but ran into a problem when entering certain CLI commands, e.g., set rpm_filter_min_hz = 100 or set rpm_filter_fade_range_hz = 100. The message I get is the following: ERROR IN set: INVALID NAME. Any idea why this command is not being recognized by BF? The following post suggests that commands such as these were working since March 14th at the latest: https://intofpv.com/t-meteor-65pro-elrs-...figuration. Attached is my "diff all" if that would be of use.

Thanks,
Jack

is bidirectional dshot enabled?

BF4.3 and the latest BF Configurator 10.8 have a bi-directional DSHOT issue and users are unable to enable it. I hope that's not happening here.

If you have the BETAFPVSX1280 board, there is a DMA resource conflict when enabling bidirectional DShot. Manually disabling DShot bitbang should solve the issue. You'll also want to make sure you're running a 4k (or 2k) PID loop, DSHOT300, and may want to overclock to 120MHz.

To disable DShot bitbang:

Recommended settings for the BETAFPVSX1280:

Code:

set dshot_bitbang = OFF
save

Code:

set pid_process_denom = 4
set motor_pwm_protocol = DSHOT300
set cpu_overclock = 120MHZ
set dshot_bitbang = OFF
save

I do have bidirectional dshot enabled and am using the GOKU F745NANO board with BS13A ESCs. Does the above apply to this board as well?

Yes it is

No, that is only for the BetaFPV ELRS board. Can you upload your CLI dump? It was not included in your first post.

Attached is the dump file. I also reattached the diff all to my original post. The quadcopter is named RSSI LOW because I have mbilozub's custom firmware installed to get the OSD warnings on DJI: https://github.com/mbilozub/fpv_custom_m...vision.hex

For those with similar issues, it seems to have been resolved in Betaflight 4.3.0 RC4. It also fixes another issue I was having where the sliders could for filters and PIDs could not be moved and saved.
