    @heiko.lizan Any elrs radio that's 900mhz or dual band compatible should work when in low band mode. If the transmitter is running v4+ you should be able to downgrade it to v3 following the elrs update guide It's normal that some services aren't running. You may need to re-enable px4 with systemctl enable voxl-px4

    Hello everyone, I am looking for some expert advice on a VOXL 2 companion computer setup for a long-range platform. I have two main integration challenges: Challenge A: VIO at Higher Altitudes To solve the motion blur and pixel density issues at higher altitudes, I am planning a 6-camera configuration. I want to use 4 downward-facing sensors (2 daylight + 2 IR) equipped with narrow-angle lenses, alongside 2 standard wide-angle sensors (front and rear). Could you advise on the best supported sensors (e.g., IMX series) for this? Has anyone successfully tuned the voxl-qvio-server for narrow-angle lenses, and what were the altitude limits you achieved? Challenge B: LAN Integration & WireGuard The payload data flow will be: External RTSP Camera -> Ethernet -> VOXL 2 (WireGuard encryption) -> Ethernet -> Digital RX. Because VOXL 2 lacks multiple LAN ports, I will need a miniature industrial Ethernet switch. Does ModalAI have any tested hardware recommendations for this? Furthermore, what is the best practice for routing this VPN traffic through the VOXL 2 Ubuntu environment without bottlenecking the CPU? We are currently evaluating the VOXL 2 for a broader fleet deployment and want to ensure the ecosystem can support this custom optics requirement. Any feedback on off-the-shelf solutions or standard configurations for this use case would be greatly appreciated. Thank you!

    @nl_vdi , if you log into developer.modalai.com, you will see the CAD models. the latest model we have is: D0012-4-V3-C28-M36-T7-K0-Starling2-Max-V3-20260317.step [image: 1781036132877-376bf0dd-494a-4bf1-8d92-1b2d91afb83d-image.png]

    Hello, I am trying to get pretty much the same thing working on the VOXL 2 with a Yolov5 model that only has one class. I am seeing similar outputs when I deploy it to the drone. @Siyu-Chen, what steps did you go through to get this working on your device? The model inferences just fine on my computer. I think it has something to do with the pre/post-processing. Thanks in advance for your help.

    @boga If SDLOG_PROFILE doesn't have what you are looking for then you can set up a custom set of log topics / rates from a file. You don't need to recompile PX4 to use it. https://docs.px4.io/main/en/dev_log/logging.html#sd-card-configuration

    @Ajay-Bidyarthy Only the inference time should be affected by your choice of hardware. The other two should be the same regardless of your choice. Thomas

    @Eric-Katzfey So you probably just need to do the magnetometer calibration procedure to be ready for flight.

    @Eric-Katzfey said in Take-Off and Land command each fly to xy=[0,0] location instead of on the spot: @LaborzaubererTHI Sounds like it may be similar to: https://forum.modalai.com/topic/2533/failsafe-landing-bug-in-px4-1-14/19?_=1713800679314 Indeed it does.

    @Dawid-Mościcki Perhaps you can ask the QGC development team for some help in narrowing down what is causing QGC to crash. If you think there is a missing parameter then in your /usr/bin/voxl-px4-start script add a new line to touch the parameter so that QGC will see it. (e.g. param touch SDLOG_MODE)

    I reflashed firmware and reconfigured drone manually (not using automatic scripts which platform detection) and problem vanished. Probably there is something wrong with detecting actual drone version in those automated scripts.

    If any1 will have similar problems in future don't follow guide : https://docs.modalai.com/sentinel-user-guide-pre-flight-setup/ See those docs : https://docs.modalai.com/voxl-elrs/ All You need to do is voxl-elrs -b, then on aperture go to ExpressLRS and choose bind Can be closed.

    @enrico-bandera-0 OK got it. You alluded to this, modifying something like hub.c (Generally if it's not showing up, we need to find some flags to add. For example, we added some USB modems like this: https://gitlab.com/voxl-public/system-image-build/meta-voxl2-bsp/-/blob/qrb5165-ubun1.0-14.1a/recipes-kernel/linux-msm/files/patches/005-telit-option.patch https://gitlab.com/voxl-public/system-image-build/meta-voxl2-bsp/-/blob/qrb5165-ubun1.0-14.1a/recipes-kernel/linux-msm/files/patches/004-quectel-usb-wwan.patch ) We'll likely need to find similar for TUSB8041 and then try to add if it's not showing up by default. Are you plugging this TUSB8041 hub into a USB port or using custom hardware? Have you located anything from TI that tells us what flags to enable? That's where I'd go next, see if vendor has clues and then we can try it out.

    @Amin-Bassiri RB5 uses voxl-px4-imu-server . You can verify the IMU data with voxl-inspect-imu imu_px4
