I have packet sniffer operating with CC2531 USB and smartRF EB respectively. However, somehow I find packet sniffer can not sense and display traffic from certain problem sensor device in certain channel(25 in my case). but I can see from router receiver log that those packets has been sent and successfully replied back(indeed, replied Ack from router can be shown in packet sniffer). Also holding device/change orientation can change the behavior and packet sniffer can sense and show packet from those devices. All devices are CC2430 based
This observation leads me to think whether the frequency of those 3 devices are slightly different(sensor, router,sniffer) . so I would like to know what is the packet sniffer operation frequency? what is bandwidth of packet sniffer operating range in certain channel?
Thanks
