IWR6843ISK-ODS: 3D people Counting

Part Number: IWR6843ISK-ODS

I finished up the ROS modification for 3D people counting demo. When I launched my sensor it launched without any error. But, I can't see any published output ( Point cloud ) on the Rviz window on my linux machine. 

 
I used the following cfg file to run a 3D people counting demo. 
 
 
Please any suggestions or advice to fix the output issue ( not publishing the point could ) to look at it?

    Hello

    Can you please help us understand  the intent of the change  and accordingly in what direction the changes were made.

    In order to check/debug the data:

    1. Required data is available on the device's output port.  (Not in ROS) --> TLV's are structurally correct.

    2.Information like tracks/point cloud can be correlate to the real world scenario (Not in ROS)   --> On sensor detection works well.

    3. Without the  modifications RVIZ is able to show  required points.

    4. Has the dataoutput from device changed compared to what the ROS/Rviz  driver expects

    5. Were any modifications made to ROS/Rviz  driver to accommodate

    Above will confirm that mmWave sensor and its output is as expected.

    For how to assimilate the data from mmWave sensor's data into the ROS environment you may refer to the example on TIrex for point cloud based ROS driver and extend that for additional information you are trying to send to the ROS ecosystem.

    Debugging custom ROS driver (#4, #5 above) and helping parse it in the ROS environment is outside the scope of forum support.  You may want to try the ROS forums for this.  See ROS.org

    Thank you,
