IWR6843ISK: Antenna Config Question in mmWave Demo

Miguel Navarro
Prodigy 30 points
Part Number: IWR6843ISK

What config in antenna corresponds to a 60+- azimuth and +=15 elevation.  It is a little confusing because in the drop down that has 60 degrees only 1 antenna and 2 rx are used.  Where do I find more information about the different antenna configs?  My second question is that in the SDK reference, certain CLI commands have acceptable values and said they are enumerated in the docgen but I could not find anything anywhere that corresponded  to this.

Thank you.

    Should I just ignore that and use what's in the chirp configurator:  Here is what I did there, there is no mention of the antenna configs:

    Hi Miguel,

    For now, I would ignore the antenna configurations, go with using 3Tx 4Rx, which is fully utilizing the device's antennas. This will give you the best field-of-view and best resolution performance. The trade off is that more antennas mean more power consumption.

    As for the CLI commands and their appropriate values, look at Section 3.4 in the SDK User's Guide: [sdk_3_install_directory]/docs/mmwave_sdk_user_guide.pdf. This explains every CLI command with value boundaries.
