I am IWR6843ISK-ODS with 3D people counting demo, I re-flashed my sensor with 3D_people_count_68xx_demo.bin from ( mmwave_industrial_toolbox_4_8_0\labs\people_counting\68xx_3D_people_counting\prebuilt_binaries). To make sure the radar itself works with the people counting demo (using the GUI on a windows machine). and it was successfully works.
I used the following cfg file.
Then, when I connect the sensor to my Nvidia Jetson nano board and run the command to launch the sensor, its launching and the light DS2 is On, also when I walk front the sensor the DS2 light is blinking ( attached video ) without any error as shown in
Now, my sensor is launched but not publishing the output, even I am not able to see output on the console (rostopic echo <topic_name>)
