No, it seems to pass all of those steps

Did you follow the getting started guide first to verify that it works as described there?

Does it fail at any step?

Hi Kenneth, I have downloaded the latest version of J-link, but the sniffer is still not returning anything. I'm wondering whether the problem is with my understanding of the API. Is the 'example.py' script supposed to work right off the bat or do I need to change somethings around (besides enter the port number of the sniffer module when instantiating the sniffer class)? As of now i can run the 'example' module and identify which port the sniffer is on but the sniffer is not picking up any packets.

def setup():
    global mySniffer
    
    ports = UART.find_sniffer()
    print(ports)
    #Initialize the sniffer on COM port COM19.
    #mySniffer = Sniffer.Sniffer(portnum = 'COM31')
    # Or initialize and let the sniffer discover the hardware.
    # mySniffer = Sniffer.Sniffer()
    # Start the sniffer module. This call is mandatory.
    print(str(ports[0]))
    mySniffer = Sniffer.Sniffer(portnum = str(ports[0]))
    mySniffer.start()
    mySniffer.scan()

    # Wait to allow the sniffer to discover device mySniffer.
    time.sleep(5)
    # Retrieve list of discovered devicemySniffer.
    d = mySniffer.getDevices()
    # Find device with name "Example".
    #dev = d.find('')
    
##    if dev is not None:
##        # Follow (sniff) device "Example". This call sends a REQ_FOLLOW command over UART.
##        mySniffer.follow(dev)
##    else:
##        print("Could not find device")

above is the only part of the example script that I changed (the setup function), I printed out the com port that was found just to make sure its the right port and got rid of the device filter. my out put looks like this:

I know there currently is an issue with Wireshark version: 3.2.0, so you may try Wireshark version: 3.0.7 and/or wait for 3.2.1 that is supposed to be released any day now.

You can also try to install the latest SEGGER j-link / nRF command line tools:
