We cannot access the download, it requires authentication. Is there a fix for this issue?

@kitkatSG There's generally a couple of different possible video distortions. One is due to the vibration from the motors. If you mount the camera on rubber dampeners you can remove most of this type of distortion. But of course the drone is moving and that causes motion as well. We don't have a recommendation on gimbal but would love to hear if you are able to find something that works well for you. And we have not tried any GStreamer stabilization software so cannot comment on that, but would love to hear if you find a software stabilization solution that works.

@Chad-Sweet Alright, if MAVROS hasn't been tested on the RB5 drone then what is the currently established method of programmatically flying it?

Thanks. CTV, CTU and CTT*: detected by usb, connects to wifi / Q Ground control and can be armed / throttled. For some reason these just worked after I pushed the button and powered them on, didn't have to go through the full-flash process. *For CTT it was a Q Ground Control related issue. I saved the parameter file from CTV and loaded it onto CTT.

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.

@rstoleru There are a few different modem options, you can see in the dropdown on this page: https://www.modalai.com/collections/voxl-add-ons/products/voxl-lte?variant=32449203601459 Most NA folks order the WP 7610 while EU folks order the 7607. The supported bands vary but you can look up the datasheets from Sierra Wireless for more info. You can enable / disable certain bands via. AT commands, in NA for example, we legally have to disable band 5 for civilian drone flight.

@Adrian-Hidalgo All right, thanks. I will check them step by step, and hope it will be solved soon

@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.

@Eric-Katzfey FYI, I just moved /lib and /usr/lib to /data. This allowed to have enough space for my work. Thank you.

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?

Thanks! I was able to do that. I just wanted to make sure before finding a tool small enough to be able to do that, and trying to twist the lens without knowing if it should be twisted.

@Cody-David-Graham Thank you for moving over here! Will pass this along to the team.

No, I don't believe so. I only have one RB5 in the lab.

@Jey-Lites Please be aware that we are currently shipping our VOXL 2 drone (Sentinel) and that you can purchase the VOXL 2 board without the drone as well. The VOXL 2 features the same Qualcomm QRB5165 device that is on Qualcomm Flight RB5 but in a much smaller form factor. Please refer to the comparison of our development platforms here: https://www.modalai.com/pages/development-kits

@modaltb hello, when will the next SDK release be available? Would love to the UARTs working for external FC. Thank you.

Hi @Cliff-Wong , Thanks for showing the streaming method using gst-launch command. I have used a similar command to stream camera=2 (suppose this one is 4K camera in my RB5 as I check all cameras from 0 to 4). However, when I increase resolution of video more than 640x480, the color of the video looks weird. For example: 640x480: [image: 1655693397940-640x480.png] But when increasing resolution higher than 720x480, e.g., 1920x1080, the color of the image is weird. For example, blue color on the EXIT board will turn to orange (I cannot upload the large image on this website). Do you know how and where to fix this issue? Btw, I have increased bitrate=10,000,000 in qtiqmmfsrc but it does not help.
