AWRL6432: Does AWRL6432 support the Dynamic Power Saving feature?

Champs,

Does AWRL6432 also support the Dynamic Power Saving feature (rlRfDynamicPowerSave) like as AWR6843?

Best regards,

    Hi Hayden,

    The power management framework on AWRL6432 is different than any low power API available on AWR6843. The application note found HERE walks through several strategies to achieve low power on xWRL6432 devices. Further documentation can also be found at: <SDK_ROOT_DIR>/docs/api_guide_xwrL64xx/power__xwrLx4xx_8h.html

    Best Regards,

    Kevin

    From sdk, mmwave_dfp, there is option of the power saving "T_RL_API_SENS_DYN_PWR_SAVE_DIS".

    (dfp_sensor.h)

        /*!
