AWR1642BOOST: OOB Number of Chirps and RangeFFT-size

Hello Sugawara San,
The config file for the OOB is generated based on the user inputs provided on the mmwave demo visualizer GUI, this includes the number of chirps and number of samples etc.
There is an profile configuration file available in the SDK , this is named "profile_2d.cfg"which has the following configuration
profileCfg 0 77 7 7 58 0 0 68 1 256 5500 0 0 30
chirpCfg 0 0 0 0 0 0 0 1
chirpCfg 1 1 0 0 0 0 0 2
frameCfg 0 1 32 0 100 1 0

Here you can see that the frame config has a loop 2 chirps (chirp 0, chirp1) looped 32 times. So there are total of 64 chirps in a frame. The number of samples per chirp is 256 (you can see that in profileCfg command) and hence the range FFT would be 256 point.

Regards,
Vivek
