@m4v3r @tom Have you looked at this thread? Seems similar https://forum.modalai.com/topic/247/how-am-i-able-to-change-from-wifi-to-lte-connection?_=1634754422256

We have been using OpenVPN for quite a while and I haven't come across this issue before. If that is what you are also using, they have a pretty active forum: https://forums.openvpn.net/ I would recommend asking there.

Your video points to a bad camera configuration. The tracking camera cannot produce the resolution that VLC is receiving.

No problem at all, I'll get our docs updated so it's more clear, definitely not a rookie mistake, we should call it out!

Hey, I played around with them today a bit and found yes, your values did reduce the frequency with which the failure occurred so I'll continue tweaking there, thanks a lot. Actually your link was double-helpful since I was looking for those specific parameters that regard the takeoff for quite some time now as well (without success...) ;D I understand this is actually more closely related to PX4 but I very much appreciate the help anyway. I sincerely don't even remember anymore why yesterday I thought this must somehow boil down to the fact that it's running on the VOXL-Flight hehe.

@Eric-Katzfey Voxl-streamer has been working fine so far with our current software, and I can test against QGC 3.5.6, so the main issue to worry about is the power issue you described. Could the custom UVC driver code be made available? The Boson IR camera is currently a critical component of our project

Thanks for your help. I realized that I hadn't configured the cameras correctly. I ran the voxl-configure-cameras and set it up correctly. Now I am getting the position estimates in QGC.

Hi @modaltb Flight deck attached to a custom drone. After ARM, the propellers were spinning, but the drone remained in place, as you can see in the video. The video from the Hires camera is displayed on the monitor .

Thank You for Your responses. Unfortunately Mission Planner doesn't see the device. I also tried via nuttx-shell, but voxl doesn't get any response from stm32, so it's probably a problem with the hardware.

@blakekrpec As I understand the ECL/EKF library integration so far, you can run several instances that each will fuse different sensor combinations (with individual blending) to accommodate for estimation state errors and the like....

Hello @evigdorchik, Could you try a different usb. We have seen that by changing the usb sometimes that works. If that doesn't work, try another computer. There have been a few instances where changing workstations fixes the issue. LMK how those go

Not modalai, but something that helped me debug this very same issue was installing voxl-portal, and using that to view the qvio stream, which will overlay the points onto the tracking camera screen. If it creates points at your drone's motors and feet, then I presume it would be a problem

Is it possible to get the core unit currently as I have been waiting from so much time ?

I didn't know Docker had this feature, so thanks for that tip! Docker built on VOXL is running at version 1.9.0 and from some articles I read it looks like multistage build started in 17.06 (https://docs.docker.com/engine/release-notes/prior-releases/) So I don't believe this is supported.

Thanks @modaltb! I just searched for "voxl-logger" and nothing came up because it's not the name of a project. I will spend some time exploring the repos.

@Chad-Sweet how many ekf_imu instances would you suggest running on a VOXL-FLIGHT in general, considering a decent workload already on the VOXL -part? cheers

Thanks, Chad!

We got it to work by just navigating to the launch file and invoking the roslaunch command from there (and excluding the package name): roslaunch voxl_mpa_to_ros.launch. Thanks, @Alex-Gardner!

Thank your for your reply. The command is pip3 install opencv-contrib-python-headless (=title of the question). Ubuntu docker is a good but not enough . I need this (opencv python package) on the target board, again like supported by modalai's python numpy package. Please help me to create/ download/install this python package on a voxl board. I need it for later using as ROS node (written in python)

@Alex-Gardner Sounds good. We'll look into it. Thanks!
