  @Steve-Sager Great to hear! Just to confirm you flashed the latest platform release, 0.9? Making a note of your issue. It's very unusual that you would have to manually edit the qgc_ip. Thank you for being patient.

  Wanted to update this by saying I experienced same issue, but I resolved this by disconnecting tracking camera that had been installed upside down. So, if anyone is reading this in the future....try disconnecting your cameras attached to the board

  I can calibrate stereo by using "stereo_front" and "stereo_rear" now. But I cant detect the chess board in a frame which rectangle is small. I will make a new chess board for calibration. Thanks!

  I have enabled voxl-tag-detector on boot, it did not help. I used systemctl enable voxl-tag-detector and in the **.service I used Restart=always .

  Hi @Adrian-Hidalgo, I finally realized why the issue happened. I put a wrong wire connection between the CW pair with the esc connectors under the wings. I used to connect the red wire to match the red connector of esc for all motors. That's why all motors spin in the same direction. So, after checking one of old pictures I took for m500, I found both red and black wires should be reversely connected to the side of esc for the CW pair (3, 4). And the shaking issue is gone after this. I didn't realize this detail before. All right, everything works well now. Thanks again for your help!

  @Alex-Gardner I'm looking forward to the fix as well. Which version will it be released on? Is fix applied to voxl-camera-server or voxl-qvio-server?

  Seems to be an issue with QGC itself. The latest v4.2.3 I’m running is where it’s failing. If I revert back to the latest 4.1.* (4.1.7) it works.

  @DarkKnightCH Use a flat tipped screwdriver or similar device to slowly pry it out. Take your time working both sides of the the Hirose connector. Take care as the pins can get bent if too much force is applied

  Hi Jonathan, The underlying pipelines for the CV sensors are all delicately built and only support very specific resolutions. I'll update our documentation to better reflect this, but in general: The stereo pipeline can only do 30hz(for now, we're working on this) since it's very custom and the tracking camera can do 30,60,90, and 120hz. The hires camera is more standard and has more robust pipelines implemented to support more standard video stream configurations. As for the manual exposure/gain, have you set the auto exposure mode to "off", if not you're just setting up the starting point for the camera and the AE library will still perform it's usual duties. If you're still having issues after this let me know and we can dig through more of what you're seeing.

  I think you'll need to create a new service that behaves like voxl-qvio-server ? That might be the easiest if you want to drop it. Maybe try copying qvio-server and modifying to publish mocap data?

  @modaltb I see. It's good to know the story If 22027 is the default one, it will be all right. To be honest, I didn't touch the CBRK_IO_SAFETY before, and it's a bit weird why it was automatically modified for some reason. Actually, I was trying to refresh a re-compiled 1.11.3-0.2.3 with my modification (increasing GPS log rate). So, I guess it might reset the value to 0 by PX4 default. Anyways, thanks so much!
