IWR6843ISK: 6262700021

Hello,

I have a question regarding the chirp configuration for IWR6843ISK with MMWAVEICBOOST.

I want to send two different chirps (different start frequencies) one after the other.

 - chirp A -> FFT -> Chirp B -> FFT (loop)

Is this possible and where can I set it?

    HI, Kim:

    To send two different type of chirp, you will need to define two type of profile, through profileCfg.  But in SDK, the only way to support multiple profile, is through subframes.   You will have to define two subframes.  Please search advFrameCfg in SDK users guide.  You can also find profile_advanced_subframe.cfg profile in the mmW demo profiles directory for example usage.

    But if you are using radar studio for raw data capture, you can define multiple profileCfg, and just choose different profileID for different chirp.  

    Best,
