![]() For example, to sniff on Channel 15 using aĭevice mounted at /dev/ttyACM0 with RSSI included in the Wireshark output: cd path-to-pyspinel python sniffer.py -c 15 -u /dev/ttyACM0 -crc -rssi -b 460800 | wireshark -k -i. If you Configure Wireshark to display RSSI, you must also include the -rssiįlag when you run the sniffer tool. Use the -b flag to specify the baud rate (if it was changed from the default) The debug port, as described in Flash the If following this guide, the nRF52840 DK should be attached to the host machine by Thread network you are attempting to sniff.

To get the Channel from a device in the target Thread network: The Mesh Local Prefix is listedĪs IPv6:MeshLocalPrefix similar to wpanctl.
