Hi @Matt-Turi !
Thank your information!

Thanks! I just had to manually focus it.

Trying to follow up this question:
When I use apriltag to fix pose, Can I get fixed pose topic by using voxl_mpa_to_ros ? Thanks

This sounds like a Linux networking issue. We don't have any experience doing what you are trying to achieve. VOXL runs Linux though. You'll likely have to set up the Linux networking to handle your usecase. It might be easier to try to get what you are attempting to do working on a Linux desktop and replicate those settings on VOXL

That is largely dependent on your drone, sensors, and how well they are calibrated and integrated.

Our reference drones can map fairly well with stereo image sensors in an outdoor environment, but they are setup with the source code for our customers to modify for their end application.

You can check out voxl-mapper source code here. We are frequently updating it and making improvements.

A specific metric is tough as there are so many variables.

@modaltb Thank You Sir

We confirmed that the PWM is cutting off at the same time, so it's possibly an initial velocity difference thing, unless you guys have other thoughts.

So it sounds like Dan bought the wrong cameras

We got maybe 1/10 mile in an urban setting, and have had reliability issues. We placed the antennae as far away from power and more than 2.6" from each other on both transmitter and drone. Any recommendations would be helpful. Thank you.

Thank you. I could not get video from the uvc device over voxl-streamer, though I could access the test video and the stereo cameras/anything plugged into the MIPI ports. I've had a problem with the newer UVC-server program. I need to check my notes it was a few weeks ago but somehow it wasn't working so I fell back on the ffmpeg due to time limits with the intent of going back to the UVC server application as it's a better solution. I will post a specific issue after looking it over again.

And @tom, also thank you.

VOXL 2 uses apt, and not opkt. Check out the docs here: https://docs.modalai.com/voxl2-platform-release/

You should just need to run

apt update apt upgrade

OK got it.

If it's not showing up via lsusb, typically we would solve that by rebuilding our open source public facing kernel with some new USB ids (we even give a docker container that is ready to build the kernel) along with instructions on how to safely test the kernel before flashing it. Check it out here: https://docs.modalai.com/voxl2-kernel-build-guide/

I haven't looked around much, but surely if this DJI drone is a development drone, they should also provide such convenience to their developers, so I'd give DJI a shout and see what's up!

@Sam-Armstrong awesome!

I am also facing same issue, tried multiple times yet unable to download, please help

Yes there's a lot of interference there, I will change the Wi-Fi mode to softap and give it a further test see if it happen again.

Thanks for your response.🙂

@kitkatSG @LudwigBAH Copying my response from another thread:

Here is an example of how to send an AT command to the Quectel modem:

echo -ne "AT+QNWPREFCFG=\"mode_pref\",LTE:NR5G\r" | busybox microcom -t 1000 /dev/ttyUSB2

The above gets ran as part of rb5-modem in order to set the network preference to allow both LTE and 5G.

Here is a link to the Quectel RM5* series modem AT command manual, you can probably find a relevant AT command to use there: https://www.quectel.com/wp-content/uploads/2021/05/Quectel_RG50xQRM5xxQ_Series_AT_Commands_Manual_V1.2.pdf
