AWR1843BOOST: rlRfGetTemperatureReport() will stop updating temperature readings with fast frame rates

YAFENG YUN

Part Number: AWR1843BOOST

Hello，

I try to get BSS temperature by call rlRfGetTemperatureReport()

If I set my rlFrameCfg.framePeriodicity as 10ms, the temperature acts as expected, changing every second.

If I set my rlFrameCfg.framePeriodicity to 5ms, the temperature will NEVER update again. If I wait 10 minutes, the same, old values will still be reported. Only when I sensorStop, or slow down the frame rate will the temperature update with new values. It's almost as if something is being starved out when the frame rate is extremely fast.

Hello, Ishita

The "software overheads" chapter of "TI mmWave Radar Interface Control Document" is very useful for this problem,

This problem can be solved by configuring CALIB_MON_TIME_UNIT and CALIBRATION_PERIODICITY reasonably according to this documentation.
