Hi All,
I still have doubts in the representation of SNR and Noise values received from OOB demo. In OOB demo the SideInfo structure values are represented as integers which means that it is in dB. I concluded it from https://e2e.ti.com/support/sensors/f/1023/t/870592 . Please correct me if I'm wrong.
So I captured some set of data and decoded Side Info TLVs. The Side Info values in each frame is higher than expected. Giving Side Info TLV from one frame below,
07 00 00 00 64 01 00 00 ec 00 a8 02 9a 00 96 02

When I decode the above values, I'm getting (SNR,Noise) pair like this,

I also referred the mmWave Demo Visualizer code and is using the same method to decode the values. And after decoding the SNR and Noise Values are multiplying with 0.1 to represent in dB. So I get confused with all these representations.
So please direct me how can I capture the SNR and Noise data in dB from OOB demo.
Thanks
Arun
