IWR6843AOPEVM: vital signs and tracking demo doesnt detetct vital signs

Part Number: IWR6843AOPEVM
Other Parts Discussed in Thread: UNIFLASH,

Tool/software:

I tried to implement the Vital Signs With People Tracking demo:

radar_toolbox_3_20_00_04\source\ti\examples\Industrial_and_Personal_Electronics\Vital_Signs\Vital_Signs_With_People_Tracking

I flashed the corresponding binary with Uniflash. I was able to connect using the Industrial Visualizer:

radar_toolbox_3_20_00_04\tools\visualizers\Applications_Visualizer\Industrial_Visualizer\Industrial_Visualizer.exe

I selected the 6843 and the Vital Signs With People Tracking option from the dropdown. Then I loaded the configuration file:

radar_toolbox_3_20_00_04\source\ti\examples\Industrial_and_Personal_Electronics\Vital_Signs\Vital_Signs_With_People_Tracking\chirp_configs\vital_signs_AOP_2m.cfg

(or the 6m version).

After starting, I began receiving data and saw the dots displayed in the GUI. However, the vital signs were never shown. I tried standing still about 50 cm from the sensor for several minutes, but it never acquired a signal and remained undefined. Wat can i do to make it work?

I noticed that there is a recurring warning "frame packet lenght read is not equal to totalPacketLen in frame header. Subsequent frames may be dropped"

    Hi,

    1. Can you check if the IWR6843AOPEVM is set in functional mode. There is a small switch adjacent to the heak sink which needs to be placed for functional mode

    2. Can you send us the picture of the visualizer screen? Do you see the frame number updating? Do you see the person being tracked?

    3. Can you also try with the visualizer from the below location?

    radar_toolbox_1_30_01_03\tools\visualizers\Industrial_Visualizer\mmWave_Industrial_Visualizer.exe

    Regards

    Hi,

    with radar_toolbox_3_20_00_04 viewer y see the frame number increasing, and the tracking working, however the vital signs part never updates.

    However with the radar_toolbox_1_30_01_03 viewer everything works and I was finally able to see the tracking, breathing and heart signal. The "frame packet lenght read is not equal to totalPacketLen in frame header. Subsequent frames may be dropped" warning still appears but right now that is not important.

    Thanks for your answer
