Unfortunately i don't have the raw feed button. This is what my vio tab looks like:

When I try clicking on the little tv-icon at the top, nothing happens.

To be sure I configured everything correctly here is my config:

system-image: 1.8.06-M0054-14.1a-perf
kernel: #1 SMP PREEMPT Wed Oct 22 04:13:18 UTC 2025 4.19.125
mach.var: 1.0.1
SKU: MRB-D0014-4-V1-C27-T0-M28-X0
voxl-suite: 1.6.2

Is 1.6.2 the newest SDK ?
I donwloaded the SDK from here: https://developer.modalai.com/asset/eula-download/188

@zauberflote1 I updated my system to the latest SDK 1.6.2 but unfortunately when I am in the VIO tab in voxl-portal, nothing happens when I click on the little tv-icon. Is there anything I need to configure to display the camera overlay?

Hi everyone,

we managed to get OpenVINS running on our setup (similar to a Starling C27). In the VOXL Portal, under the VIO tab, the trajectories and motion estimates look good so far, so OpenVINS itself seems to be working correctly.

However, we can’t find the ov_overlay in the Camera tab to visualize the tracked features from the tracking cameras. According to the documentation
(https://docs.modalai.com/voxl-open-vins-server), there should be an ov_overlay available in the camera view, but it doesn’t appear for us.

Has anyone encountered this issue before or knows what might be missing or misconfigured on our side?

Thanks a lot for your help!

Update:

I bought an Alfa Networks AWUS036ACS and it worked out of the box with the M0151 board

Update:

I did some further testing and noticed a somewhat inconsistent but repeatable pattern related to SKU reconfiguration and power cycles.
After reconfiguring the SKU (MRB-D0014-4-V1-C27-T0-M22-X0) and then power cycling the VOXL2, the SoftAP network is broadcast as expected. After a second power cycle, the network is still being broadcast. However, after a third power cycle, the network disappears again and is only restored after reconfiguring the SKU once more.
In addition to that, client connectivity is inconsistent. In some cases I’m able to connect to the WiFi network from my PC without issues, while in other cases the connection attempt starts but eventually fails.

Hi ModalAI team,

we’re currently struggling to get WiFi running reliably on our VOXL2 and were hoping someone here might have some insight.

We initially tried using the M0151 adapter, but since we couldn’t establish a stable WiFi connection, we switched to an M0141 adapter with an Alfa Networks AWUS036EACS USB WiFi dongle. Our setup is otherwise identical to the Starling 2 configuration.

What we’re seeing right now:

• The USB WiFi dongle is consistently detected (lsusb shows it, wlan0 is created).

• After boot, however, no SoftAP network is broadcast in most cases.

• Sometimes, after reconfiguring WiFi using voxl-wifi in SoftAP mode, the network comes up and we are able to connect successfully.

• After a full power cycle (disconnecting and reconnecting power), the SoftAP is usually gone again, even though the dongle is still detected.

Reconfiguring WiFi or restarting services occasionally brings it back, but the behavior is not deterministic.

If anyone has seen similar behavior, has recommendations for debugging, we’d really appreciate the input. @Vinny @Alex-Kushleyev

Thanks in advance!

@Alex-Kushleyev Thanks for the help !

@leandro I found M0188 here: https://docs.modalai.com/M0188/#3d-drawings

I did some additional testing and was able to narrow things down a bit. After reconfiguring the WiFi as a SoftAP using voxl-wifi and then rebooting the VOXL, the network now shows up consistently again. So the broadcast issue seems to be resolved for the moment. However, the core problem remains: I still can’t actually connect to the AP — the connection attempt starts, prompts for the password, and then fails just like before.

If anyone has ideas on what else I could check or has seen similar behavior with this setup, I’d really appreciate the help.

Hi guys,

I have a quick question regarding the coordinate frame orientation of the AR0144 tracking camera. As far as I understand it, the camera coordinate system is defined such that the z-axis points out of the lens, the x-axis to the right and the y-axis downward when looking through the camera.

What I am currently unsure about is the originally intended orientation of the tracking camera frame itself. I created a small sketch showing the two possible orientations I could think of. Which one is the correct one, the left or the right figure?

Additionally, I was wondering whether en_rotate in the voxl-camera-server.conf modifies the camera extrinsics, i.e. whether it applies a rotation to the underlying camera coordinate frame such that the extrinsics would need to be configured accordingly (for example upside down), or if it purely affects the image stream orientation without altering the extrinsic calibration at all.

Thanks a lot in advance!
