Hi @modaltb,
I'm getting the exact same problem with the same parameter settings. I tried running voxl-vision-px4 -o and I was seeing no messages when attempting to switch to position control. I'm also not seeing any Odometry section in MAVLink Inspector.
I'm seeing no errors when running voxl-vision-px4 as a service or in command line.

Hi @Lynn-Koudsi ,
Hmmm, this one is confusing me a bit, if you're available maybe we could setup a screen share on Monday to troubleshoot? I'm be available 8:15-10:00, 12-2 and 4-5 PST, or Tuesday anytime after 8:15 AM PST.
Thanks!!
-
@modaltb 12-2 works!
Also just for more context, I had done a clean image installation at V3.1.0 and had removed my data folder. I'm thinking the issue is that calibration files are not there. I tried running voxl-cam-ros but it's not finding left and right yaml files. I tried just pushing the sample calibration files from https://gitlab.com/voxl-public/utilities/voxl-camera-calibration but it won't find ost.yaml.
So I guess my question is, is there a default data folder available online? Or can you provide the default factory data folder?Thanks!
-
Just sent out an invite for tomorrow, if I can get the SN of the m500 I can get you the calibration files we have in our production database in advance and that might get things going!

@modaltb Thank you!
Serial# is M20000000TJ

Hi @modaltb
I'm getting the same problem as described by Lynn. I had also done a clean image installation at V3.1.0 and had removed my data folder.

@Liping My issue was resolved by installing voxl-qvio. You can reference the diagram here to learn what services are needed for the different interactions.
-
@Lynn-Koudsi Thanks Lynn. But in my case, the issue still exists after installing the voxl-qvio.
What are your installed voxl package versions?
I installed some latest stable version packages.
yocto:~# opkg list-installed | grep "voxl" libvoxl_io - 0.5.4 voxl-cam-manager - 0.2.2 voxl-docker-support - 1.1.1 voxl-hal3-tof-cam-ros - 0.0.2 voxl-modem - 0.10.0 voxl-mpa-tools - 0.1.6 voxl-nodes - 0.0.8 voxl-qvio-server - 0.2.1 voxl-rtsp - 1.0.2 voxl-time-sync - 0.0.1 voxl-utils - 0.5.2 voxl-vision-px4 - 0.8.1 voxl-vpn - 0.0.2 voxl_imu - 0.0.4 -
@Liping Is voxl-qvio actually running? You can check by calling
systemctl status voxl-qvio-serverit might be that you need calibration files for the tracking camera -
@Lynn-Koudsi It shows waiting for imu and camera. Could you help to point out where is the calibration file located? Is it this calibration process (https://docs.modalai.com/calibrate-cameras/) that you refer to?

voxl-configure-vision-px4 voxl-configure-modalai-vl -
@Liping that's a curious problem... try checking the status of the imu and camera servers:
systemctl status voxl-camera-server
systemctl status voxl-imu-serverIf you check the status of voxl-qvio again, does it say it failed? or it waits forever?
You should have the following calibration files:
etc/snav/calibration.stereo.xml home/root/.ros/camera_info/left.yaml home/root/.ros/camera_info/right.yaml etc/snav/calibration.downward.xml home/root/.ros/camera_info/downward.yamlBut I'm pretty sure you're going to need
/data/modalai/opencv_stereo_intrinsics.yml /data/modalai/opencv_stereo_extrinsics.ymlI got those by running the calibration process you referenced.
-
@Liping I just realized that you don't have
voxl-camera-serverinstalled. You will need that. I also found that having bothvoxl-camera-serverand voxl-cam-managerhas given me some issues so I would recommend uninstallingvoxl-cam-manager -
-
@Lynn-Koudsi Thanks a lot! The issue has been solved. The QGroundControl shows meaningful ODOMETRY data now. As you mentioned, the issue comes from the voxl-camera-server and voxl-imu-server. voxl-qvio can not get data from both the camera and the imu.
Besides, I noticed that the configuration of the camera and imu does not work as expected. It may be caused by the conflict of the old (imp_app, voxl-cam-manager)and new (voxl-camera-server, voxl-imu-server) camera and imu ipk.
To make it simple, I flashed the image with the System Image 3.2.0 (https://developer.modalai.com/asset/eula-download/64) without installing the voxl-suite, since I want to use the new Modal Pipe Architecture (https://gitlab.com/voxl-public/modal-pipe-architecture).
I manually installed the following voxl packages:
yocto:/# opkg list-installed | grep "libmodal" libmodal_json - 0.3.4 libmodal_pipe - 1.7.6 yocto:/# opkg list-installed | grep "voxl" libvoxl_io - 0.5.4 voxl-camera-server - 0.5.5 voxl-dfs-server - 0.0.7 voxl-docker-support - 1.1.1 voxl-imu-server - 0.7.8 voxl-mpa-tools - 0.1.6 voxl-qvio-server - 0.2.1 voxl-utils - 0.5.9 voxl-vision-px4 - 0.8.1Then I run the configuration commands for the qvio, voxl-vision-px4 and camera (voxl-imu-server has done some default configuration during the ipk installation):
yocto:/# voxl-configure-qvio -f rm: cannot remove '/etc/modalai/voxl-qvio-server.conf': No such file or directory loading qvio config file Creating new config file: /etc/modalai/voxl-qvio-server.conf The config file was modified during parsing, saving the changes to disk enabling voxl-qvio-server systemd service Created symlink from /etc/systemd/system/multi-user.target.wants/voxl-qvio-server.service to /etc/systemd/system/voxl-qvio-server.service. starting voxl-qvio-server systemd service Done configuring voxl-qvio-server yocto:/# voxl-configure-vision-px4 -f rm: cannot remove '/etc/modalai/voxl-vision-px4.conf': No such file or directory Created new empty json file: /etc/modalai/voxl-vision-px4.conf The JSON config file data was modified during parsing, saving the changes to disk enabling voxl-vision-px4 systemd service Created symlink from /etc/systemd/system/multi-user.target.wants/voxl-vision-px4.service to /etc/systemd/system/voxl-vision-px4.service. starting voxl-vision-px4 systemd service DONE configuring voxl-vision-px4 yocto:/# voxl-configure-cameras ...Regarding the configuration of the camera, i was following the guidance in https://gitlab.com/voxl-public/modal-pipe-architecture/voxl-camera-server to use the command
voxl-configure-camerasprovided byvoxl-utilspackage.I rebooted the VOXL and checked related services (camera, imu, qvio, voxl-vision-px4) using
systemctl statusBut I noticed that the
voxl-camera-serverwas not automaticly started on boot.
So I enabled it with:yocto:/# systemctl enable voxl-camera-server@modaltb Please correct me if any step was not right or there is a better way.
In addition, I also followed the https://forum.modalai.com/topic/70/warning-px4-disconnected-error-message-from-voxl-vision-px4 to solve the WARNING PX4 DISCONNECTED error message from voxl-vision-px4

WOW! Thanks @Lynn-Koudsi for the help, when we setup the forum this is the kind of interaction we were hoping for, just awesome!!
Sorry for the setup and 'wonkyness' right now, we've been somewhat caught with getting pre-release software out there without all the setup/docs lined up.... so we're doing a little catchup it seems.
@Liping there until we have our docs updated, if this is working, I'd say this is a good approach!
Thank you both for the details, we'll relay this through the team.
