@Eric-Katzfey I just had m0015 cameras connected to the J6 connected via a m0076 connector, which I have unplugged and the behavior still persists. I also have a 5G Modem Carrier Board connected with a doodle labs radio, can't unplug this though or else there is no connection to QGC. Yes, I am connected to the standard GPS pins on J19 which I believe to be connected properly, as QGC can detect the compass properly. I have tried swapping the TX and RX pin connections, but this resulted in the GPS to not even work with px4. The current configuration works just fine with PX4.

@Eric-Katzfey I see the GPS_RAW_INT message come in, but all of the fields are zeroed out and there is no cursor on the map:

I tested it with PX4 and I was getting reasonable lat/lon positions along with all of the other data fields being filled out.

Hello, I am currently trying to use stereo cameras (m0015) within a custom ROS2 application using the voxl_mpa_to_ros2 (version 0.0.6) package on the VOXL2 (SDK 1.4.0), but I am only able to see left stereo camera when running the mpa to ros converter. Here is the output of ros2 topic list:

/imu_apps
/parameter_events
/rosout
/stereo
/stereo_disparity
/stereo_disparity_scaled
/stereo_pc
/voa_pc_out
/vvhub_aligned_vio
/vvhub_body_wrt_fixed
/vvhub_body_wrt_local

According to the docs, I should expect something along the lines of /stereo/left and /stereo/right. Recording the topic /stereo and then playing it back confirms that only the left camera is being recorded. Here is the output of /etc/modalai/voxl-camera-server.conf, which was created by running voxl-configure-cameras 10

}

Both cameras are fully functional when viewing from the portal.

How can I get data from both of the cameras?

@Eric-Katzfey We just got the m10s gps that you linked and are still having some trouble. Again when running px4 the gps works as expected, but running ardupilot seems to cause some issues. Getting the same behavior as the m9n, where running voxl-inspect-gps has no output:

Any ideas on what to try next?

@Eric-Katzfey Thank you for the response, we don't have that GPS and would like to try to get the M9N to work if possible. Is there any troubleshooting we can try before purchasing a new unit? PX4 has a .conf file in /etc/modalai, I don't see one for Ardupilot, could this be an issue? I have also tried to tweak the parameters in the file /data/APM/defaults.parm and also through QGC, but have had no luck.

Hi,
I am currently using a voxl 2 (SDK 1.4.0) running ardupilot version 4.7.0-4803bc14. I have attached a Holybro M9N GPS micro via the J19 connector. When using px4, I am seeing the GPS reading on the map for QGC, and the command voxl-inspect-gps gives out the expected readings. We are trying to use ardupilot, and for some reason when disabling px4 and enabling ardupilot, I lose the ability to see the GPS in QGC and running voxl-inspect-gps shows nothing - however the voxl still connects to QGC. In the documentation, most of the GPS information is linked to when using px4, can GPS be used with ardupilot? If so, how?

I found an issue when trying to use the front stereo setup with 2 OV9782 sensors (camera configuration 12) on a newer SDK (1.4.0+) version. On a fresh install, I ran the command: voxl-configure-cameras 12 and then rebooted. Then when running voxl-camera-server, the following errors and warnings pop up and flood the terminal:

WARNING: preview buffer pool for Cam(stereo), Frame(16) has 0 free, skipping request
ERROR in pipe_server_get_num_clients, channel should be between 0 & 31

Then when trying to view the image previews in the portal, no image appears. Running one camera at a time worked, but

I do not believe this is a hardware issue, as without touching anything, I installed a fresh 1.3.5 image on the system, ran voxl-configure-cameras 12, rebooted, ran voxl-camera-server with no errors, and the image appears just fine in the portal.

One thing that I did notice was that even though there were no images in the 1.4.0 and 1.4.1 portal instances, there were more boxes to check for different image viewings. In the 1.3.5 portal, there was only the option to see 'stereo_grey'
