I am using the IQ values collected from the Channel Sounding example. The data in the 0 section seems to indicate that this channel is not in use? For example, as shown in the picture, the three IQ data in the middle are all 0. So, is the frequency of the channels before and after these three data values 4 MHz different?

Hi

If you're looking at the IQ values from the cs_de_report_t, our guess is that you're hitting the following condition for some channels here. This means that the controller believes the measurement on a channel of not good quality due to interference for example. The solution we have in cs_de.c by default ignores measurements on these channels and leave IQ values at 0.

Best regards,

My primary concern is the channel spacing. For example, if there are three channels skipped in the middle, The spacing between the channels immediately before and after these three channels  is 4 MHz?
