    Hey @arvind_g3aero So, it does look like you were able to get this working with the dev release of voxl-camera-server which is great to hear. The natural progression of a software package is through dev-> staging -> release. So, this version of voxl-camera-server will be released in a future SDK. There will most likely not be a backport onto the 1.6.2 SDK

    Hi ModalAI team, I’m developing a sub-250 g UAV and am trying to determine the lightest practical VOXL 2 / VOXL 2 Mini camera and sensor architecture for the aircraft. The target payload functions are: Daylight RGB video / imaging FLIR Boson+ 320 thermal video Camera input required for reliable VIO / navigation Lowest possible total camera, adapter, cabling, and interposer mass I am specifically trying to avoid carrying unnecessary stereo, ToF, or additional cameras if they are not required. Could you recommend the exact minimum hardware stack you would use for this application? In particular: For reliable VIO, can we use a single tracking camera, or is a stereo pair required/recommended? Which current ModalAI tracking camera/module would give the lowest installed mass? For RGB imaging, what is the lightest currently supported color camera/module that can provide useful daylight video? For a Boson+ 320, is the current recommended connection still: Boson → M0201 → coax → M0181 → VOXL 2 J8? Can the Boson, RGB camera, and minimum VIO camera configuration operate simultaneously on one VOXL 2 / VOXL 2 Mini? If yes, could you provide the exact ModalAI part numbers/interposers/cables required and, if available, approximate individual masses? Is there a supported camera configuration close to this, or would it require a custom voxl-camera-server configuration? The aircraft has a very tight mass budget, so I am trying to establish the absolute minimum viable sensor stack rather than starting from one of the larger development-kit camera configurations. Thanks, Yisrael

    @Nitin-Varma-Vegesna said in Apriltag relocalization not relocalizing?: @Nitin-Varma-Vegesna Is there any release that is known to work for April Tag Detection? https://gitlab.com/voxl-public/voxl-sdk/services/voxl-tag-detector The dev branch is the most recent - I have to check with the engineering team on this as I am unsure the priority of april tag detection and positioning based off it. Will relay back

    @ApoorvThapliyal Thank you for your help. also I was able to work with jazzy by only subscribing and printing with node. since error only occurred when I tried to echo the topic and not when another node is subscribing it. but using docker seems like most viable option to me since I m using ubuntu 24.04. Thank you for your help again

    @Mastermind That sounds like it would be possible, but obviously depends on the driver of the wlan adapter you choose. You would need to implement the bluetooth broadcast portion of Remote ID. The source code for voxl-remote-id is here and only currently supports the Wifi portion of Remote ID

    @Zachary-Lowell-0 as mentioned I have set offboard-mode in voxl-vision-hub.conf to "off". I did a flight test shifting to offboard-mode, The drone was able to execute the script in a stable way without any jittery motions or trying to come back to home position. These are the flight logs, https://review.px4.io/plot_app?log=e32a28df-cbba-4765-8499-6fe46e2ff890

    @tahawaru Okay, that shows you have 1.14.0-2.0.78. If you want to build 1.14.0-2.0.63 then you need to check that version out instead.

    @Eric-Katzfey I figured out the problem. I changed the mavlink pipe to mavlink_onboard keeping the channel number as 1. Setting the channel number as 2 seems to fix the problem. I haven't looked into the implementation of modal-pipe architecture but I thought that the channel number is just used by the client of the pipe (kind of like an open file descriptor number?). Basically it looks like having the channel number as 1 breaks the mavlink pipe somehow.

    @dario-pisanti Hi Dario, Thanks for sharing your issue. I'm also working with the Qualcomm Neural Processing SDK on VOXL2 Mini. The error you mentioned could be due to: Model compatibility issues during conversion. SDK configuration, especially for GPU. Double-check the GPU-specific settings in $SNPE_ROOT/bin/envsetup.sh and try running a simpler model to verify the GPU setup. Have you managed to resolve this, or do you have any additional details? I'm also trying to use the QNN SDK with ONNX runtime on VOXL2 Mini. Best, Manu

    @AndriiHlyvko The issue is with dependencies. The emulator is built using the actual filesystem used on the VOXL platform so you get all of the correct dependencies. With voxl-cross it is sometimes very difficult to setup the dependencies properly.

    voxl-logger to log files at my computer

    @rsr4z , voxl logger will create different directories and files for different data that it will be logging, so using a single socket for this will now work. If you REALLY want to have the log files saved directly to your PC and your network connectivity has the bandwidth to do it, then you can potentially map your desktop as a network drive (using sshfs or something like that). Then you can save your logs to the network drive. However, you should be aware of the following potential issues: ssh is encrypted, so encryption of data will take some additional cpu usage on VOXL (proportional to the amount of data) network-mapped drives are not always reliable, especially if you connection is not reliable, but there are sshfs flags you can try to automatically reconnect, etc.. if there is not enough bandwidth to save the data over your network connection, voxl-logger can get occasionally blocked and will drop packets on the MPA side Another option you can consider is saving the logs on voxl, and then using periodic rsync to get the data to your PC. rsync works over ssh as well. I just did a quick search and this came up (i did not try it): fswatch -o /src | xargs -n1 -I{} rsync -a /src /dest (https://stackoverflow.com/questions/12460279/how-to-keep-two-folders-automatically-synchronized) you would need to copy your voxl2's key onto your desktop so that you don't need to enter your password every time.. Finally, if you did not want to write to the VOXL2's drive at all, you could save the logs to tempfs (/dev/shm) and then rsync from there to your PC and have rsync delete the files after syncing in order to avoid filling up your RAM, but you have to be careful and not delete files that are still being written by the logger.. Hopefully this gives you a few options to think about..

    @relevinsky What steps are you doing to compile the voxl-tflite-server code? It should be done within the voxl-cross Docker image. Also why SDK 0.9? Let me know how I can help. Thomas thomas.patton@modalai.com

    Looking at what BlueOS is setup to do...it might be easier to modify modalAI's voxl portal than to get this to work with the current setup. The things I am looking to add immediatly is log download and additional ways to get information and status on voxl services such as journalctl logs
