Hello, I just purchased a VOXL 2 flight deck with 5G modem support.($3k) I was wondering if the VOXL 2 comes with PWM control? Or do I need an extension board?

I also have the same issue, I have used the portal and QGroundControl to view camera feed but there is a delay in both, enough so that it is not reliable to fly depending on the feed alone. I have tried disabling the portal and the docker to see if it would help but not much of a difference. If someone could help us figure out a way to stream the Hires RGB camera in 4k resolution with minimal delay if possible? Or even just lower the delay with 1080p resolution?
Please and Thank You.

LuxF7HD is a betaflight flight controller. https://rpg.ifi.uzh.ch/docs/IROS18_Falanga.pdf developers from the university at zurich were able to bridge the betaflight controller to the onboard computer. we think we have the wiring portion done, but we need to somehow send the parameters changes from the voxl to the betaflight controller via a serial port. we are using serial port j10012 currently. please let us if you have any ideas on how to bridge the two

Thank you for the quick reply. I have successfully setup the wiring portion. I was wondering if there is a guide to show me how to modify the code to use a different UART?

Can someone guide me in this process? I am trying to use a Betaflight flight controller instead of the PX4 onboard flight controller. Is there a guide available for this type of setup?

Re: Using Motion Capture Systems (Optitrack) for Position Estimation

I have seen people use the vrpn package along with other packages to stream data from motion capture systems such as VICON. Would someone please help me get started with how to Download this package on my VOXL-Flight-Deck?

I have done a first flight using a controller and the drone is responding fine. I wanted to use Motion capture to provide the Pose data, is there a way to do this on the VOXL?

I am thinking of using a different flight controller than PX4, is it possible to flash the VOXL to use Betaflight Firmware? Has anyone done this before?

How can I get VICON data? How would I download pyvicon or pymavlink? I am currently using a docker to run kinetic ROS and when I try to install using Python3 I get errors. Please help me to get started with flying my drone autonomously for the first time.

Can someone please help me with my first flight? I setup a roskinetic docker and used the mavros_test example that was provided online. However I am unable to fly the drone in figure eight motion. I am able to see the rostopic list from host pc but nothing is being published on the topics.

My goal is to run a custom Python script that uses motion capture system to provide pose data over vrpn_client_ros for hover and land. I started with the tutorial first but because I could not get the drone to take off I am now stuck. Any help would be highly appreciated.
Thank You.

P.S My drone is able to arm via QGroundControl over UDP connection.

Thank You, Solved!

Does the tutorial still work with "VOXL / VOXL 2 USB Expansion Board with Fastboot v2"? I have a different board I was just wondering if the process is the same because in the video they switch to Fasboot mode with a switch the board I have does not have a switch but a button.

Can someone guide me through the steps to unbrick my VOXL 1 flight deck using the Expansion V2 board. I could not find the V1 board so I just bought the V2 and now I cant find a tutorial to help me unbrick my VOXL.

I have tried pushing the FASTBOOT button while attaching the Power Cable however the board does not respond. I still can not ADB into the device or do the ./install command in the latest Firmware folder. Any help would be highly appreciated.
Thank You

I just replaced the wifi antennas but no luck still WLAN0 still not shown in ifconfig… please help me out. Do I need to RMA device?

@modaltb
What do you suggest I should do then?
Do I need to flash the board? Or take it down a version?

I have tried setting it back to factory, to my understanding it should broadcast as VOXL-<MAC ADDRESS of VOXL> however, it doesn't broadcast anything. Here is the output:

My software version:

The Wi-Fi was working fine out of the box and then when I attached it to my drone the Wi-Fi card is not being shown in ip a or ifconfig... I don't know what could have happened. Is there a command to enable the Wi-Fi adapter? My setup contains 4 motors 4 ESCs attached to a Power distribution board. The VOXL is powered via LiPo 3s 11.1v battery connected to the Power Module v3. I can ADB in but there is no WLAN0 in ifconfig. Please advise what I should do. I don't have a Debug Add-On board so I can't flash it to factory defaults.
Print out of ifconfig:

@modaltb said in Can't connect to QGroundControl over wifi...:

mavlink status

Here is the print out of the mavlink status, I see there is /dev/ttyS4 at 921600 baud rate. Is this what we need?
I've checked the MAV and Serial configuration they are the same as you have provided.

The connection to QGroundControl via Wi-Fi still doesn't want to connect.
VOXL-VISION-PX4 printout:

Also, the Wi-Fi doesn't work anymore as well.... there is no WLAN0 showing up on VOXL anymore.

Sorry for the late reply, Ill be checking in more frequently now. I really need help setting this up so I can continue my thesis. Thank you for your help.

Hello I've tried all three different ways to connect to the internet but none of the ways allows me to connect to QGround without wire connection. I can ADB and wire connect but WIFI doesn't work. I had it working for just a little while but it doesn't want to connect anymore. I have updated the firmware to 1.13 from QGround via wire and uploaded the Parameters from the GitHub page. I would appreciate some guidance. Thank You.
