Hello,
I can you please post the output you got when you ran the 'nrf_sniffer_ble.bat --extcap-interfaces' command at step 3 b in Installing the nRF Sniffer capture tool?
OK, I see you are getting a permission error when it tries to open COM8 (10-Jan-2023 12:48:38 (+0100) ERROR: Error opening UART could not open port 'COM8': PermissionError(13, 'Acceso denegado.', None, 5)). Any chance this port may be kept open by another program like a serial terminal emulator?
Apparently not, I don't have any serial port terminal opened
OK, can you clear the log and check if you get the same permission error after a reboot of your PC?

Have you tried to see if you are able to open COM8 from another application such as TeraTerm, etc?
Have you tried to see if you are able to open COM8 from another application such as TeraTerm, etc?
yes, it´s able to open
Sorry, but I do not think I have seen this before on Windows. Could you try to run Wireshark as admin to see if it makes any difference?
