Re: Radio S32LE samples don't go negative?


 

There seem to be an offset according to capture level and signal intensity, but I can not (at least not easily) determine the offset.

Is there a constant offset? Try listening to a steady carrier which should result in a sine wave in the audio.

?There is something wrong. I'm looking at the samples I get from the radio rx path - I don't see negative samples, just positive ones, but the sample format is signed 32 bits. When reading from loopback, for example, I get the negative and positive samples, as expected. This explains weird behaviors I was experiencing. Anyone can confirm this issue?
