    • Stereo right side out of focus

      Hi, I just find out my right side stereo cameras is out of focus.

      Screenshot from 2022-06-30 11-13-06.png

      This situation is make me hard to do the camera calibration since the right side image is blurry and hard to detect chess board tag. In fact I tried to perform camera calibration twice and it took me very long time and unfortunately failed in the end.

      Is there anyway to fix this problem besides camera calibration? Or a camera calibration with bigger tag would solve my problem (mine is A4 size)? Any suggestion is welcome, Thanks!

    • Disconnected from Wi-Fi

      Hi,We use the m500 for indoor flight.

      Sometimes while we setting program or config it would suddenly disconnected from Wi-Fi (our Wi-Fi mode is station btw..)and the fan ran with full speed. Thus, we have to unplug the battery to reboot m500.

      Do you know what kind of problem might cause this situation? and is there any way besides hard reboot to solve it? My guess is Wi-Fi condition cause this problem, since our Wi-Fi here sometimes is not quite well and after it disconnected it just never coming back unless hard reboot.

    • How can I get fixed pose via QGC or ROS

      Hi, Recently I am trying to use voxl-tag-detector to update pose in indoor environment.

      When I check pose by using voxl-inspect-pose -f I can get the fixed pose correctly, but if I use roslaunch voxl_mpa_to_ros voxl_mpa_to_ros.launch and check rostopic /qvio/pose, I can only get local pose ,same as QGC and mavros.

      So I did a little research and I found out this topic: How can I see the apriltag offset in ROS. It shows that fixed frame is going to be published in the upcoming version.

      According this, I wonder now if there is any way to use ROS or QGC to get fixed pose? Or I have to create my own node to publish fixed pose data? My current system image is 3.6 with voxl-suit 0.5.0. Thanks.

    • Test voxl service on x86 system

      Hi team,using voxl for a while and it's pretty good to use.

      I would like to know if there is a way to simulate the environment of voxl in an x86 architecture?

      For further example, can I setup an x86 architecture and flash a voxl image into it? Or any way to let me test some voxl service on an x86 system?
