    @gauravshukla914 ,

    I'm not aware of any calibration required for ToF.... This procedure should work out the box so I'm confused: https://gitlab.com/voxl-public/ros/voxl-hal3-tof-cam-ros#visualization

    I'm sure you have this correct, but where have you attached the camera? It should be connected to J3 here: https://docs.modalai.com/camera-connections/#camera-ports

      @modaltb Yes I have attached it properly to J3 and we followed the same process but when I launch the file it says the file /data/misc/camera/irs10x0c_lens.cal is missing. I looked into the directory as well there is not such file exist.
      I tried this and I do get frames out of it. So that means it is attached properly

        Hi:

        Could you please list the content of your /data/misc/camera directory? I am wondering if the process of generating that file was interrupted and now it doesn't attempt to generate it anymore.

        If there is anything in the /data/misc/camera directory I would move it to another temp directory - say /data/misc/camera/temp and try running the app again.

        Also as a quick experiment, I would put in just the TOF camera, remove other cameras and run the app again to see if it helps.

          @hitendra Thanks for the suggestions.
          Here is the list of file present in data/misc/camera directory
          camera'.png
          each of these files are just have these of 0 bytes each

          default installed voxl_hal3_tof package gives error as resolution not supported. And changing the resolution from the source as we did mentioned earlier does run the package but than stops at irs10x0c_lens.cal file being missing
          tof_error_2.png
          after changing the resolution and compiling again
          tof_erro3.png
          and hence topics are created but they don't publish any data

            That lens cal file is created the first time the driver is launched, it does take about 20 seconds to generate. Changing the resolution in the code probably is just covering up the fact the TOF camera isn't launching.

            The CAM_ID changes based on which sensors are plugged in due to a quirk in the Qualcomm camera subsystem. It's most likely the wrong CAM_ID is being assigned to TOF in the config. Maybe a camera is/was unplugged?

                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!

                  @Chad-Sweet
                  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

                      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.
