ArkFlow 1.14 Stable Documentation

Hello, I am trying to get my Arkflow working on the modalai flight core v2.

I flashed the most recent stable 1.14 release, but it appears not all of the paramters are showing up. A few that are missing are


I am following the documentation here: ARK Flow | PX4 User Guide (main)

I understand this is main branch, but I can not seem to find this documentation for a 1.14 stable release branch like I can for 1.13 or 1.12

I am an idiot. You need to enable

before those earlier parameters become available. making request to documentation in case anyone else gets confused

I was at the same point when I started using Ark Flow. I think in terms of the docs it would already help if the two parameters were mentioned at the top, directly after Enable optical flow fusion by setting EKF2_OF_CTRL. When going through the settings cronologically, it would make more sense for me to first enable everything that’s necessary to activate all the following params.

Thanks so much for sorting this. FYI, this is the approach I used in the generic setup docs: DroneCAN | PX4 User Guide (main).

If this is truly generic, it might be good to make the generic ones a master copy and link to them from ARK. I don’t think we’re quite ready yet.

I need some help here while using the following:

  • AFK Flow
  • Pixhawk 6C
  • PX4 (1.14.0) stable


Problem: (the drone isn’t stable in position mode)

  • Initially the takeoff was not good (the drone was circling).
  • Upon releasing the Roll/Pitch stick of RC, the drone wasn’t stopping, then I had to move the stick to opposite direction to stop the drone.
  • Switching to “Land” mode didn’t worked.
  • Sometimes, it was holding the position and sometimes it was moving freely while hovering.

I see that Alex is assisting you in Drone isn't stopping on releasing Roll/Pitch stick of RC while using ARKFlow for local positioning · Issue #22385 · PX4/PX4-Autopilot · GitHub

It might be best to make this a separate post on the PX4 forum as this post has been resolved

I am also running into an issue.

All of the SENS_FLOW params are not showing for me. I am also on PX4 1.14 stable release.

Not only that, but I cannot set parameter values to decimal points. They appear to be integers. Like setting UAVCAN_RNG_MIN will just go to 0. It does not go to 0.08

I think I always had to refresh (Tools > Refresh) in order for the SENS params to show. Not sure why this is necessary though.
