    You're selecting TOF+Tracking, but there is no tracking sensor installed. So the TOF_CAM_ID is probably coming out incorrect.

    Do you have a tracking camera? If so, please power off and install
    If not, can you please try export TOF_CAM_ID=1 ?

    thanks!

    we installed tracking camera and reconfigured voxl using voxl-configure-camera

    and tracking camera is working
    Screenshot from 2021-01-13 11-23-59.png

    than we tried to run tof package again but still the problem persist. we even tried to change the TOF_CAM_ID but still no change.

      OK, good the tracking sensor is working. Sorry about this, the tof setup is still in beta. We clearly need to document the setup way better.

      Can you please print which version of system image you are using (voxl-version)? The error implies an older system image which does not support that hal3_tof_cam_ros.

      ERROR: Libcamera sending post-processed TOF data. App does NOT get RAW16 TOF camera data

      The error above implies an older version of libcamera which would use tof_cam_ros instead

      Just FYI, the TOF_CAM_ID needs to match what is in the launch file. This message shows what is in the launch file:
      /tof/voxl_hal3_tof_cam_ros_node/camera_id: 0

                Assuming the ipk is installed, can you please then run this command and then try the ROS node again?

                      OK, good progress. That should be working. Can you give it a full power cycle and see if it says up?

                          Unplug power from the VOXL and plug it back in. Then try the test over. You look like you're in a working state.

                              It is the way for software to tell which TOF driver should be used. Setting to 1 supports the HAL3 method you are using, setting to 0 supports the older libCamera method using tof_cam_ros

                              The HAL3 method is intended to give the developer more control over the pipeline

                                  Hi @gauravshukla914 ,

                                  Thanks for the help with this. We've released a new beta version of the voxl-hal3-tof-cam-ros that supports auto detection of ToF and defaults the persist.camera.modalai.tof setting properly.

                                  It will be in out next voxl-suite release, but is available from our dev channel here if you are interested in using this link

                                  The updated readme is here.

                                  Thanks!
