    @RoyAzriel 1.6.4 release is tested on Starling 2 now, go ahead and use that from the link I emailed you.

    @cguzikowski , Sorry for the delay. Regarding the new HW not working, since you have two identical setups, i would recommend swapping components to identify what exactly is not working. This is the most efficient way to diagnose it. From the logs you provided, the ov64b camera is detected and initialized, it seems, but no frames come in, which could be a cabling or interposer issue. I will get back to you with an update on the lens shading tomorrow. Alex

    @bschulzhf PX4 will only correct incoming messages. Something external will have to also run TIMESYNC with PX4 to estimate the offset and correct and incoming PX4 message timestamps that it wants to align. voxl-mavlink-server does this for a few messages.

    @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

    Hi @Prasad-Pawar , This is a bit out of scope for us (we don't really develop for QGC, just use the standard releases typically). Have you tried https://discuss.px4.io/c/qgroundcontrol/15 ? Thanks!

    Hi @modaltb , Thank you for your message. I did actually choose "Yes" but it didn't store the ROS folders and files. It stored the Python packages I installed and the docker images. So, I would like to confirm if the voxl-backup command will save the folders in data. However, it is okay. I took me some time to recover but now all good. thank you again

    @shlee853 Yes, voxl-streamer uses RTSP. What kind of wireless link are you using to stream the video? What application are you using to view the video? What kind of latency are you seeing with this setup? And, ultimately, what is your target latency? The answers to these questions will help guide potential solutions.

    libvoxl_io unfortunately won't work inside of a Docker. Are you communicating via MAVLink? If so, you can send mavlink commands to voxl-vision-px4 to be forwarded on the the flight controller over serial.

    @Alex123 I just realized right now when I was powering up my m500 that I said to use 24VDC in an email.... this is OK for that power module, but the max is 25.2VDC, so no problem dropping it to say 16VDC!
