nRF52840 sniffer SLIP protocol

[jbrowne44]

I am able to load the sniffer_nrf52840dongle_nrf52840_4.1.1.hex firmware on my board, but I cannot find the SLIP packets on a USB virtual port.  I see the ASCII packets, but I can't seem to find the packets that use SLIP protocol which the wireshark extcap expects.  Do I need to do anything to get the firmware to start sending SLIP packets or am I on the wrong virtual port?  I don't see any other virtual ports available.  I am using osx and I am using the Adafruit nRF52840 Feather express.

Here is the ASCII output that I currently see:

Thanks,

It looks like I might not have successfully uploaded the sniffer hex file.  Do you have a version of the sniffer hex file that works with the latest version of the Adafruit nRF52840 Feather express and the latest bootloader?  Here is my current bootloader setup:

UF2 Bootloader 0.2.6 lib/nrfx (v1.1.0-1-g096e770) lib/tinyusb (legacy-525-ga1c59649) s140 6.1.1
