AWR6843ISK: BPMCFG for 3D configuration

Christoph Hintz1

Part Number: AWR6843ISK

Hi Everybody,

I saw that in SDK 3.05 the profile_2d_bpm.cfg turns on the bipolar modulation in the radar. This is a really nice feature. Is that also working for a 3d configuration? If yes it would be great to get some pointers on how to enable it.

Thank you for your help.

Best,

Christoph

    Hello,

    You will see the BPMCFG command is support for all the profiles, but the commands typically do not enable this feature. If you set the chirpCfg commands to turn on multiple antennas and configure the bpmCfg command for this according to the SDK user's guide you can add this feature. But it only supports a 2D BPM configuration. You can use this with a 3D configuration, but only for 2 antennas at a time.

    Regards,

    Hi Jackson,

    Thank you very much for your information. I have been successful in sending a configuration to the radar, nevertheless it still seems to not start. My configuration I send to the radar with SDK 3.05 is

    Is there something obvious that is incorrect with it?

    Hello Christoph,

    Have you run the demo in CCS debug mode to see what the error is when you send the configuration?
