How do I access elevation data capabilities for TI MM Wave Radar sensors (AWR1843 Boost).

The TIAWR1843Boost MM Wave Radar sensor has elevation sensing capabilities. During seup, when I create the .cfg file through the mmWave demo tool provided by Texas Instruments i can plot this data. The .cfg file stipulates that the sensor is configured for Azimuth 15 + Elevation. When i run the file though, the radar object has the elevation resolution as read only and set as NaN. It is only configurable through the .cfg file. I have verified that I am not recording any Z-axis values (only 0).
Has anybody found a work around for this?

AWR1843BOOST is not a supported TI Radar board by the support package. However, with a few minor changes to the code, you may be able to get AWR1843BOOST to function with the support package in MATLAB.
Thanks,
Gayatri
