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

The frequencies used by channel sounding are defined in the BLE spec and use a set of 72 channels spaced 1MHz apart, so if these channels are in increasing order, there should be 4MHz between these channels, correct. I assume this frequency range is jammed or of poor quality in your testing environment.

Best regards,

Simon
