    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?
