This a great video. I am following your setup for my own holybro x500. Have just succeeding in getting the Bluejay flashed and can see motor speed in telemetry file. Will now setup filter and do test flight. Thanks much.
I had a similar round of fun and games with a speedybee 55amp 4-in-1getting the config to reverse and save etc when using a Black Cube so seems like it can be quite a common thing.
Have been following your video in setting up notch on holybro x500 with Pixhawk 6c. Your filter setup gives very nice smoother flying performance! When looking at gyro noise with ArduPilot filter tool, it appears that there is some unfiltered noise at 4th harmonic. Would it be safe to filter 4 harmonics (4 motors x 4 harmonics x 3-triple filter, 48 total filters) without overloading processor? They caution about this in ArduPilot setup instructions. Any insight would be appreciated. Thanks again for super video.
Hi Andy. I purchased the x500V2 exactly two years ago and was inspired to try using RPM feedback now after watching your video. I updated to the latest 4.5.7 with Pixhawk6C-bdshot and tried my own parameter values as well as mission planner presaved. Still, I can not get the serial connection to work in BLHeli. I can also generally not connect with ESC configurator and usually get the port is already in use warning. Once or so I did get a connection with the ESC configurator, but the read function did not produce anything and there was no flash option. Do you think it is possible that I have older ESC that do not support bdshot?
The ESCs do not support bdshot out of the box, you need to install BlueJay first to get that functionality. Passthrough doesn't work on the main outputs you need to use the aux outputs, and even then its more reliable to use betalfight for that part of the configuration.
@andypiper5285 Thanks I have tried and am unable to read and hence flash. That said, I saw you made a change to the throttle based notch code in ardupilot (AP_Vehicle.cpp). It appears this is based on the rcin for throttle. Have you considered instead notches on a per motor using the rcout PWM? I realize throttle will be the biggest channel mixed in to each motor, but pitch, yaw, roll will have a notable effect too? Am I missing something, or does this sound reasonable? -- EDIT -- It wasn't clear looking at GitHub, but according to the wiki, under multi notch, INS_HNTCH_OPTS=2 will accomplish this. I would have to clone the repo to understand because the code does appear scalar.
