AWR1642BOOST: QUESTION About AWR1642 detecting distance limiting without GUI ?

Part Number: AWR1642BOOST

I have some queries on the SRR project in the ADAS section.

1. Is it possible to reduce or customize the distance to 10 meters and 5 meters without the GUI tool, HOW ? (i already limited the range 20 and 80 by using SRR mode and USRR mode and i used multimode also) ?.

---> by i change detection range by following this thread https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1302479/awr1642boost-query-on-hard-coding-srr-program/4947541#4947541

2. How do we change the detection range dynamically ?

    Hi Sankar,

    1. Please go through the following document to understand how to adjust your chirp parameters to configure the sensor to the specs of your choice.
      https://www.ti.com/lit/an/swra553a
    2. To change the detection range dynamically, you can reconfigure the profile and chirp cfg during the runtime of the application over the UART interface.

    Hai Kaushik,

    the provided LINK Doesn't work, when i click the link its shown ERROR 404 not found ?

    ===> i tried so many time all these configuration but why doesn't work ?

    Hi,

    This issue has been resolved you in your other thread.

    For the SRR demo, the configuration is hard-coded in the code

    thank you
