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.

@modaltb Thank You Sir

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.

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

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

Thanks! I just had to manually focus it.

Hi @Matt-Turi ! Thank your information!

Dan, Check out this thread: https://forum.modalai.com/topic/589/flying-in-poorly-lit-conditions?_=1654205018092 TLDR is you need enough features for QVIO to pick points out for VIO. So you either need a diffuse light source that can illuminate features or some other low-light sensor that you would need to integrate with QVIO.

@Djalma-Ribeiro You can create a systemd service file and enable it to run on boot and have it execute the OpenVPN connection command. Here is an example on how we have used it in the past on a VOXL: [Unit] After=voxl-time-sync.service Requires=voxl-time-sync.service [Service] Type=forking ExecStartPre=/bin/sleep 2 ExecStart=/usr/sbin/openvpn --script-security 2 --daemon --config /etc/openvpn/KEY_FILE [Install] WantedBy=default.target Won't be exactly the same as above but that's the general idea.

I had the same issue. Updating the voxl_mpa_to_ros package resolved it for me: opkg update opkg install voxl-nodes

Thank you so much sir, Its working now

Thank you for your reply. Actually, I was using VOXL in a softAP mode and not in Station Mode that's why I was facing this issue.

@Alex-Gardner Thank you, that fixed the issue.

Hi @steveb2014 , Using a TELEM port should get you the same interface as standard Pixhawks, perhaps some params need to be changed for baud etc. Do you have specific issues or errors you are seeing? Thanks! Also, some info on our use of a gimbal with FlightCore here --> https://docs.modalai.com/voxl-m500-gimbal-user-guide/ although it was using a little 2-axis PWM controlled gimbal.... I think the MAVLink approach is better.

@chaitanya Sorry. My goal is that cell phone can control VOXL flight deck. Therefore, I need a MAVSDK library( e.g. libmavsdk.so) at Android. Then I can use the library to send command to control VOXL flight deck.

We have posted the Sentinel CAD which has the flight deck embedded. https://docs.modalai.com/sentinel-functional-description/#3d-step

We have posted the Sentinel CAD which has some of the s500 components embedded. We don't have the s500 frame as is. https://docs.modalai.com/sentinel-functional-description/#3d-step

@Chuck-Bokath Sounds like you were able to get a connection going? If not, I was going to suggest adding your ground station's IP to the voxl-vision-px4 config file under the qgc_ip setting.

We have a px4io board that will be in beta soon. It will enable more RC options. Do you have a specific protocol you are looking for?
