output RSSI and raw data #16

Hi,

how to output the RSSI and even the raw IQ data for each detected zigbee packet?

Thanks.

Unfortunately, that's not possible out of the box. Currently, the IQ samples from the SDR are demodulated and then decoded. That means, at the time when a frame is detected (by finding the preamble in the decoded data) it's not IQ anymore. You would, for example, have to introduce a second parallel stream of raw IQ data and log/dump this IQ data once a frame is found. While typical SDRs are no calibrated device, the RSSI can, then, be derived from the IQ data (you also have to take the gain into account).

Thanks a lot!
