The nRF Sniffer for 802.15.4 can help you efficiently analyze Thread and Zigbee network traffic during development, when you need to check what kind of data is wirelessly transmitted over these networks in real time. The captured frames are passed to Wireshark, which decodes the Thread, Zigbee, and other protocols based on the IEEE 802.15.4 MAC. This provides complete information about the messages that are sent in mesh networks.
