I’m looking for a packet sniffer for zigbee. Is there a sample of how to  
do this with a RTL? The one I found on google used a FPGA.

Thanks,

Hi,

there is an O-QPSK [1] phy that might be a starting point. Since you  
have a RTL dongle, I guess you plan to use the 800 or 900 MHz band. IIRC  
the chip sequences are slightly different there.

Best,  
Bastian
