You can start capture manually from Wireshark with or without the out-of-band metadata.
Capturing in Wireshark requires installing an nRF Sniffer plugin.
Installing the nRF Sniffer capture plugin in Wireshark
The nRF Sniffer for 802.15.4 software sends commands to the nRF Sniffer hardware through the serial port and reads the captured frames. The software can be installed as an external capture plugin in Wireshark. You need to install the plugin only if you plan to use the nRF Sniffer as a Wireshark capture interface.
Running nRF Sniffer in Wireshark with custom options
To start listening on a custom channel and with custom out-of-band metadata settings, run the capturing tool in Wireshark from the Interface Options window.
