    Yudi,

    You can increase the sampling rate of the vital signs demo by modifying the configuration file (.cfg). This is located in the vitalSigns_host\profile folder of the vitals signs lab folder. Specifically, you will need to modify the "profileCfg" argument. You can find out more information about this CLI command in the User's Guide of the mmWave SDK.

    Regards,

    Hi Kyle,

    Thanks for your reply. I want to increase the sampling rate to 500 Hz, but the demo cannot run when I set it as 500 Hz. Do you know what is problem? Thanks.

    As following shown, I changed the fifth number of frameCfg from 50 to 5. Then, the demo cannot run.

    Yudi,

    Does the demo run when you leave the fifth value at 50? What error messages are you seeing when you change it to 5? With a value at 5, you may not be leaving enough interframe processing time for the vital signs processing chain to complete correctly.
