@tom

It was a massive lift on my end. Many changes as you can see from the pull request. Years of development

It appears this happens when the sensors are not calibrated on the drone. voxl-vision-px4 picks up on sensor inconsistency and restarts PX4.

So, calibrated the sensors. Looks better

resolved

My fault. Found a small tear in the ribbon for the stereo cameras

RESOLVED

I think these documentation pages are the same.

https://docs.modalai.com/voxl-cross/
https://docs.modalai.com/voxl-emulator/

Not huge deal, but thought I would post ticket to track

Docker container non-deterministic fail

I am trying to start a container with the following command:
docker run --rm -it --net=host cal_compass:latest

Sometimes it starts right up. Other times it gives me this error: Cannot start container 05621665b072b85b6419f904c0ffb511a1ad07a32c1ca675820aaadbefa4a316: [8] System error: write /sys/fs/cgroup/cpuset/system.slice/cpuset.cpus: invalid argument"

Any ideas what could be wrong? Thank you for any insights

@Caleb-Rievley are you loading firmware 1.12 and 1.13 on the VOXL Flight?

ModalAI comes out with their own versions of PX4. Let me dig up that URL:

https://docs.modalai.com/flight-core-firmware/

Hello,

We have a UAV we would like to fly indoors and outdoors without landing during that transition.
I know that there is support for EKF2 GPS/VIO "fusion" using 329 as the EKF2_AID_MASK in PX4
Link to tutorial

We were thinking of manually changing the EKF2 bitmask when we fly indoors or outdoors.

My question is, are there any software/features available that would more easily support switching from GPS to VIO? Want to make sure I am not redoing work before I start.

Thank you

So it turns out that the post-running script for docker service relies on the image "hello-world:latest"

I had uninstalled that image to save space.

Redownloading image and trying again

@modaltb This worked for me. Removing the USBC cable, booting up, and then plugging in.

Wanted to update this by saying I experienced same issue, but I resolved this by disconnecting tracking camera that had been installed upside down. So, if anyone is reading this in the future....try disconnecting your cameras attached to the board

placed order via email

Hello, I would like to order the boards/connectors for integrating the FLIR Hadron

M0159
M0181
coax cables between those the boards
M0155

However, I can not seem to find them on the store.

These boards are also referenced in these docs: https://docs.modalai.com/voxl2-hadron/

@groupo We also had this issue, but we had modified the sentinel and was found to be more due to vibrations

https://discuss.px4.io/t/stopping-compass-mid-flight/42808

Nevermind, was being talked about in https://forum.modalai.com/topic/4121/compass-errors

@briandaniels15 Also, might get faster responses on PX4 related things if you post on the Dronecode forum or discord

@briandaniels15 Yes, we have seen this before, but not on a fresh sentinel. Can you upload the log file that you downloaded please

We were getting this error on voxl-streamer.

We thought it was an issue with something voxl oriented. Turns out We were using a busted version of VLC that was on ubuntu 24. switching to a different media player worked.

Posting here incase anyone runs into a similar issue. Thanks!

Hello,

Was wondering if there are any plans to integrate the IMX 327 Ultra low light.

Thanks!

@Judoor-0 Gotcha. Let me know if this doesnt answer your question.

you can use voxl mpa to ros2: https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-mpa-to-ros2
and this will allow you to access camera frame information
