nRF Sniffer has the same operating system and SEGGER J-Link Software requirements as nRF Util. J-Link Software is required if you are using the nRF52 DK v2.0.0 or the nRF52840 DK over UART.
The minimum Wireshark version required for sniffing is v3.4.7. Check the Wireshark prerequisites for version compatibility with the supported operating systems.
