IWR6843: How to output 2Hz in ROS?

Shine

Part Number: IWR6843

Hello Champs,

HW: IWR6843ISK

SW: mmwave SDK 3.5

Customer can run the out_of_box demo in ROS, but when he changed the frameCfg  0 1 16 0 500 1 0 to output 2Hz in the cfg file, there is no data returned in ROS. But the visualization GUI in windows can show 2Hz.  

How to output 2Hz in ROS? The ROS can only output >10Hz data. 

Thanks
Regards,
Shine

    Hi Shine,

    My apologies for the delay due to the holidays. We will get back to you on this by the end of the week.

    Best Regards,

    Hello Shine,

    If possible I would like a log of their terminal/console when they try to run it at 2Hz. Also, I would check if this issue is being caused by the visualization via RVIZ, or data being sent in via the ROS Driver. This can be discerned by using "rostopic" on radar_scan_pcl_0. This will list every point coming in from the sensor directly. If radar_scan_pcl_0 is empty then the radar itself is not starting.
