      @Alex-Kushleyev Hi Alex, When I hold the drone in hand and move around the room, I see that VIO is at 100%. It only fails when I shake the drone or start flying it. I'm not sure what's going wrong.

      @riteshsharma , based on changelog (https://gitlab.com/voxl-public/voxl-sdk/services/voxl-camera-server/-/blob/master/CHANGELOG) you can use voxl-camera-server package version 1.8.10 -- dowload it from here http://voxl-packages.modalai.com/dists/qrb5165/dev/binary-arm64/.

      Upgrading your SDK would also work as Tom suggested.

      Update on following up on this topic. I was able to use other camera including Logitech Brio as suggested on ModalAI webpage. It only support YUV format not MJPEG streaming. With YUV format on Logitech Brio, I was only able to get 1920x1080 at 5 fps. But could not get MJPEG working.

      @riteshsharma Was there an error in our documentation that we need to fix? Did you make some changes that you think may be valuable to others and, if so, are you willing to share them?

      @riteshsharma you are welcome. If the current approach initializes and works fine (is able to allocate all the buffers), the performance should be stable. I am a bit surprised so many buffers are needed for the encoder, there is probably some other settings in our software to change that... However since it is actually working with 11 buffers, maybe there is no need for me to test / fix that. If you do encounter any other issues, let me know..

      Hi @riteshsharma
      We usually recommend a small screwdriver (flat edge) or tweezers to actuate those small switches.
      For the FASTBOOT switch, you need to use something less likely to break the top plastic, so the back end of a qtip or a pencil is good for that one.

      @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..

      @Darshit-Desai when you are subscribing to /hires_large_color or /hires_large_grey are you planning to do some kind of image processing on these image messages in ROS? These are huge 4k images and I'm not sure how much the ros CV bridge can handle. One option is to resize the images since that typically complements image processing for whatever consumer subscribes to these image topics and will result in a speed up. Rectification also can be used to reduce the image warp.

      Another option is to play with the image sensor encodings and find something more manageable in ROS and computational power required.
