AWR2944: BPM decoding in HWA is not working

Joseph Hanna

Part Number: AWR2944

Hello,

I'm trying to implement BPM from Tx side and Rx side.

in Tx side i can see that BPM is done as expected, but in Rx side i can see there is no effect.

I can see ADC data with decoding is the same as with no decoding.

I've configured BPM decoding sequence then enabled the BPM mode by setting 1 in "bpmEnable" in fft1d parameter set.

did i miss something that makes the decoding is not working?

Thank you

Hello Josh,

Thank you for your reply.

I'm asking about the BPM removal, which is done through HWA.

I've done the part you sent and i've checked it and it's working fine.

my problem is that i can not see any effect of the demodulation after enabling it.

it seems to me that HWA BPM removal is not working or needs some other configuration.

Thank you
