  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'

  @Alex-Kushleyev It's a 3rd party camera that is not supported by ModalAI.

  @tom @Zachary-Lowell-0 Hello again. It looks like I got the build to work. I tried cloning voxl-mpa-to-ros2 and that seemed to have worked in generating the build. I also ran "git submodule update --init --recursive" to pull in the px4 messages. I tried running "ros2 launch voxl_mpa_to_ros2 voxl_mpa_to_ros2.launch" but I received the following errors as shown below.

  These are the ros2 topics that show up for me as well.

  Is there something I'm missing that I need in order to see the ros2 topic for AprilTag detection?

  @Eric-Katzfey Thank you for the reply,
  If I understand correctly, the example you provided shows MAVSDK running directly on the VOXL — so on the drone itself. However, we want to run our script on a separate PC to be able to control all drones at once. We're not sure which port to use to communicate with PX4 while also taking advantage of the relocalization handled by VOXL.

  Thank you again for your help!

  You need to push the install folder as thats where the executables live in ros2 once you run colcon build. src folder is just the code you wrote with zero executables after colcon build is run.

  Hi, I have setup the voxl-mapper on my VOXL 2 with TOF camera. I have tested figure 8 and trajectory following. They are working perfectly.

  I would like to know how can I send the goal/ trajectory setpoints to the voxl-mapper to use rrt* to create the trajectory and to follow that.

  I don't think I can just send it to /fmu/in/trajectory_setpoint, can I?

  thanks in advance.

  @Mastermind That sounds like it would be possible, but obviously depends on the driver of the wlan adapter you choose. You would need to implement the bluetooth broadcast portion of Remote ID. The source code for voxl-remote-id is here and only currently supports the Wifi portion of Remote ID
