Wireshark fails to detect nRF sniffer

[Henkie]

I'm trying to get nRF sniffer to work in wireshark. I followed all the steps from the nRF sniffer user guide, but I can't get it to work.

The issue:
- when I have the PCA10040 attached trough USB, wirehsark fails to load (freezes at "Initializing external capture plugins").
- when I do not have the PCA10040 attached trough USB, wireshark does load, and shows the nRF sniffer toolbar, but does not detect the interface when I connect the board trough USB

What I've confirmed:
- flashed the debugger to host/emulator firmware "2017 Jun 9 14:57" using J link V6.16c
- PCA10040 flashed with proper firmware, with led2 blinking, led3/4 constant ons
- PCA10040 does appear as "JLink CDC UART Port (COM3)" in device manager
- "nrf_sniffer.bat --extcap-interfaces" does not show any python errors
- using wireshark 2.6.2

Hoping someone can help me to fix this, as I'd love to use the nRF sniffer.

I think I've experienced the same issue. My problem was the USB capture driver, WinCAP or something. I needed to uninstall everything related to the USB capture driver en re-install all associated programs from scratch according to the sniffer user guide. 

This is a general driver that is used by programs such as wireshark to listen for certain packets on the USB.

My status is same with Henkie, stop in "wireshark initializing capture plugins".

Did you try the fix I suggested?

[GeorgeBlue]

yes, it's work.

I just modify the nrf_sniffer.bat
