Wireshark hangs on "Initializing external capture plugins"

This is an old ticket, but I have the same issue with Wireshark 4.0.2 (v4.0.2-0-g415456d13370) on Windows 11 21H2.

The trace below shows that nrf_sniffer_ble.bat exits after ca. 2 minutes (timeout?)

 ** (wireshark:14344) 16:51:01.710693 [Capture DEBUG] C:\gitlab-builds\builds\MsQ3pox2\0\wireshark\wireshark\wsutil\ws_pipe.c:257 -- ws_pipe_spawn_sync(): command line: "c:\Program Files\Wireshark\extcap\nrf_sniffer_ble.bat" --extcap-interfaces --extcap-version=4.0
 ** (wireshark:14344) 16:53:05.181779 [Capture DEBUG] C:\gitlab-builds\builds\MsQ3pox2\0\wireshark\wireshark\wsutil\ws_pipe.c:495 -- ws_pipe_spawn_sync(): c:\Program Files\Wireshark\extcap\nrf_sniffer_ble.bat finished in 123466.199ms

I can observe the same timeout when launching the nrf_sniffer_ble.bat directly from the command line.

It looks like this occurs only when the bluetooth adapter of my laptop is on (which adds 2 extra Standard Serial over Bluetooth COM ports). Turning it off immediately unlocks nrf_sniffer_ble.bat and Wireshark behaves as expected.

Hope this helps.

Just tested the guide here as well, with no issues. What happens if you choose "Run as administrator"? If I do not do this, I get several questions on allowing Wireshark to make changes to my device. Could this be the issue on you side?

I am using Python 3.9.6. I am following the guide from infocenter for nRF Sniffer for BLE. I am not sure what do you mean by "run the tool correctly from Command Line". If you mean "nrf_sniffer_ble.bat --extcap-interfaces" then yes. Output matched example from guide.

What version of Python version are you using? Are you following the steps provided in our Infocenter for nRF Sniffer for BLE? Have you verified that you are able to run the tool correctly from Command Line?

Before installation of nRF Sniffer for Blluetooth LE capture tool, Wireshark was starting OK, after, it hangs on startup, showing message "Initializing external capture plugins". OS is Windows 10. Wireshark version is 3.4.7 (win64).

Hello,

Can you please provide more information on what the issue is? What OS are you on? What version of Wireshark are you using?

Thanks!
Kind regards,
