Zigbee sniffer wireshark6/6/2023 ![]() The real LQI value reported by the module in the range 0 to 255 should be displayed in the ZigBee Encapsulation Protocol section, but due to a bug, this isn't actually the case (see ). The "LQI Correlation Value" is limited to a range of 0 to 127 (whereas the Ember module and the norm are defining this value for the range 0 to 255), so the displayed value is divided by 2.The "FCS Valid" field is always set to true as the Ember module discards invalid packets.The "RSSI" value is correctly sent using a signed integer value in dBm.Using the "TI CC24xx" frame format permit passing the RSSI value but has also limitations: When using Wireshark to display the packets, the raw IEEE 802.15.4 packet received by the Ember module is first encapsulated in a "TI CC24xx" frame format, then in a ZEPv2 (ZigBee Encapsulation Protocol version 2) frame format before being sent using UDP. ![]() The timer defaults to 30 seconds.Ī compiled JAR file can be found here along with further documentation. This will allow the sniffer to recover from serial port or NCP communications problems. If the NCP fails to receive a valid frame with the timeout period set with the timeout command line parameter, then the NCP will be restarted. When running Wireshark, these should also be seen in the Wireshark window. ![]() The software will print an output to the console for each packet that is received to allow confirmation it is working. Java -jar ZigBeeSniffer.jar -port /dev/tty.SLAB_USBtoUART -baud 115200 -flow hardware The ipport will default to 17754 which is the port used for the ZigBee Encapsulation Protocol - changing this may stop Wireshark displaying ZigBee data. Note that the IP address will default to the local host on the assumption that you are running Wireshark on the same computer as the sniffer. d,-device-id Set the device ID that will be included in ZEP frame w,-pcap Log data to a Wireshark pcap compatible log ![]() t,-timeout NCP restart timeout in seconds s,-silabs Log data to a Silabs ISD compatible event log m,-maxpcap Maximum filesize for Wireshark files f,-flow Set the flow control (none | hardware | software) ZigBee sniffer using Ember NCP and routing packets to Wireshark for display - GitHub - zsmartsystems/: ZigBee sniffer using. e,-rotate-end Set the channel rotation range end w,-rotate-start Set the channel rotation range start o,-rotate Enable channel rotation and set rotation interval (seconds)
