AWR1642BOOST: Is there any method to transmit 2d FFT result for all virtual antennas?

Hi,

I am trying to transmit 2d FFT result (range doppler map) for all virtual antennas to extract both range-doppler map and range-azimuth map for all bins since 'azimuthStaticHeatMap' only show the zero doppler.

With DCA1000EVM and ethernet connection with PC, I transmit user sw data through LVDS. 

the data that i want to transmit is MmwDemo_DSS_DataPathObj_t.fftout2D.

TO extract all fftout2d data for all virtual antenna, at dss_data_path.c, I modified part of azimuthheatmap to contain all fft2d result for each doppler bin(16 doppler bins)

However, as mentioned at https://e2e.ti.com/support/sensors/f/1023/p/789287/2921357

Due to limitation of CBUFF size, I cannot transmit all fft2d data through lvds by using sw configured lvds data.

Is there any method to extract all fft2d result using lvds? Or do I have to reduce the size of fft 2d( decrease the number of range bins or doppler bins)?

Thanks a lot
