      @taiwohazeez , the image is indeed blurry. Did the camera come like this or did something happen to the camera / lens?

      Also, i am assuming that the blur is not coming from the camera moving around (that is to say the camera is stationary during those image captures).

      Please inspect the lens on the outside to make sure it's not scratched or damaged, as this can also contribute to the issue.

      In any case, adjusting focus on a camera is usually as simple as turning the lens slightly CW or CCW. Since the image is almost focus, i expect that the adjustment would be within 1 full turn from the existing lens position in the lens holder. If the camera lens is being held by a plastic mount, it should have a screw on the side of the plastic mount, which clamps the mount around the lens. The screw needs to be loosened and then you can use the focus tool to turn the lens slightly while looking at the image view in voxl-portal. For this particular camera with a wide lens, the hyperfocal distance will be around 10cm, meaning that when properly focused, everything beyond 10cm away should appear in focus. With this in mind, you should some target (checkerboard is fine) 0.3 - 0.5m away and turn the lens back and forth (with the plastic tool) to try achieve the best focus. If you cannot achieve good focus (the best focus is still blurry), it probably means that either the lens is damaged dirty (front or back side of the lens).

      If you do unscrew the lens all the way out (by turning counter-clockwise until the lens comes out), don't leave the camera exposed like this for a long period of time, so that dust does not get on the camera sensor.

      Also, what is the exposure and gain reported in the stats below the image in the voxl-portal view, when you view the camera stream (without the calibration). The environment seems pretty dark, i would recommend more lighting, but let's double check the reported exposure and gain (from auto exposure). Also, please make sure your checkerboard pattern is as flat as possible (this is unrelated to blurry image, but will result in better calibration results).

      Please try focusing the camera and let me know if you have any questions.

      @Zachary-Lowell-0 Hi, let me explain what i meant by hovering mode. There is a 3-way toggle switch beside the kill switch in the transmitter (toggling down switches to position mode, toggling up switches to the autonomous mode, while toggling to the middle maintains the drone flight positioning. I have another drone that when the button is switched to the middle, it maintains the drone position (thats what i meant by hover mode). My other starling 2 drones maintains their positions when the switch is toggled to the middle position, but this particular starling 2 drone doesnt.

      Detections is pertinent to voxl-tflite-server and onboard computer vision on yolo, NOT on april tags.

      Hi @taiwohazeez,

      The " /fmu/in" prefix is used for sending data to the autopilot - you're never going to receive data from the autopilot listening to that topic.

      Look at the "/fmu/out" topics to see messages coming from the autopilot.

      Best,
      Ted

      Hi @taiwohazeez,

      That is the cable that powers the VOXL. I'm suggesting you leave that plugged in and disconnect everything else. I see you still have the VOXL 2 WiFi Add-on board connected. Disconnect that as well all the cameras on the bottom of the VOXL, ESC, and GPS.

      Please have the VOXL powered off while you disconnect everything.

      Let me know how it goes,
      Ted

      @tom @teddy-zaremba can you assist please? This is pretty urgent, I need to get this fixed. Also, the landing gears got broken, and I can't seem to be able to order new parts from the official website, is there a way I can go about it?
      Looking forward to your response.
      Thanks

      @taiwohazeez The build flow should be like this:

      cd voxl-mpa-to-ros2 git checkout dev git submodule update --init --recursive voxl-docker -i qrb5165-emulator ./install_build_deps.sh qrb5165 dev ./build.sh qrb5165 dev ./make_package.sh deb

      @taiwohazeez Could you post the error and we can take a look?

      Also here's an easier way of installing it if you just want to run this script on the voxl.

      wget http://voxl-packages.modalai.com/dists/qrb5165/sdk-1.5/binary-arm64/voxl-ros2-foxy_0.0.1_arm64.deb wget http://voxl-packages.modalai.com/dists/qrb5165/sdk-1.5/binary-arm64/voxl-mpa-to-ros2_0.0.7_arm64.deb sudo dpkg -i voxl-ros2-foxy sudo dpkg -i voxl-mpa-to-ros2 voxl-configure-mpa-to-ros2

      @taiwohazeez No problem, it would also be helpful to know what SDK version is loaded on your drone. You can check this with voxl-version
