IWR1443BOOST: FFT data from all four receive channels

Hi,

I’m using mmw demo application.

I use two configuration files
First is profile_2d.cfg. It’s from mmw demo folder.
C:\ti\mmwave_sdk_01_01_00_02\packages\ti\demo\xwr14xx\mmw\profiles

Second I get from mmWave Demo Visualizer

sensorStop
flushCfg
dfeDataOutputMode 1
channelCfg 2 1 0
adcCfg 2 1
adcbufCfg 0 1 0 1
profileCfg 0 77 916 7 57.14 0 0 70 1 240 4884 0 0 30
chirpCfg 0 0 0 0 0 0 0 1
chirpCfg 1 1 0 0 0 0 0 0
frameCfg 0 0 16 0 100 1 0
guiMonitor 0 1 0 0 0 1
cfarCfg 0 2 8 4 3 0 1280
peakGrouping 1 1 1 1 229
multiObjBeamForming 1 0.5
clutterRemoval 0
calibDcRangeSig 0 -5 8 256
compRangeBiasAndRxChanPhase 0.0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0
measureRangeBiasAndRxChanPhase 0 1.5 0.2
sensorStart

First profile have four receive channels     channelCfg 15 5 0
Second profile have one receive channel  channelCfg 2 1 0

I read data from IWR1443BOOST via my software.
But Range Profile structures have equal length 512 bytes l in both cases.
Is it possible to get FFT or ADC data from all four receive channels simultaneously?
