CC2531USB-RD: How to capture unicast packet using SmartRF Packet sniffer

Other Parts Discussed in Thread: CC2531

I am currently using Packet sniffer(2.18.0) with CC2531 USB dongle.

I can check broadcast messages.

However, i can't capture the unicast messages.

I wonder if it's possible to capture the ZigBee unicast message.

Please, let me know. Thank you in advance.

Hi hochan,

What Wireshark or Ubiqua software version are you using, and what Zigbee devices/profile are you attempting to detect? Please clarify whether the messages never show on the sniffer log or if they are encrypted. If then never appear then they are either not 802.15.4-based packets, the messages were never transmitted over-the-air, or there is a channel mismatch between the sniffer and Zigbee devices. If they display as encrypted then it's possible that you need to add the global TC Link Key. Here are some further resources for your consideration:
