IWR1642BOOST: Output packet on UART wrong

liting wang

Part Number: IWR1642BOOST
Other Parts Discussed in Thread: IWR6843,

Hi，

I use "Save Data" of "VitalSignsRadar_Demo.exe" to save the collected "dataoutputfrommevm.bin" and convert it to hexadecimal. It turns out that each TLV is only 224 bytes instead of 256 bytes. Its structure is completely different from the "output package on UART". What is the reason?Why is it 224 bytes instead of 256? 'Vital Signs Output Stats' Why not 128 bytes but 88 bytes?

Thanks in advance,

Best regards

Hi,

You can get details about the Vital signs TLV at the below location

radar_toolbox_2_00_00_06\radar_toolbox_2_00_00_06\source\ti\examples\Medical\Vital_Signs_With_People_Tracking\docs\vital_signs_with_people_tracking_user_guide.html

From the description, you can see that Vitals signs TLV size is 0x88 (136) bytes

TLV sizes need not be 256/128 bytes. They are designed as per the contents of the TLV

Regards

Sorry, I can't understand. My Vitals signs TLV size is 0x58 (88) bytes.

Hi,

As you are using the vital signs demo on IWR1642BOOST, the demo is no longer supported. In the current vitals signs demo on IWR6843, the length of the vital signs TLV is 0x88 (136) bytes
