Wireshark doesn't see nrf51 dongle sniffer

[Han Vertegaal]

The nRF sniffer is not listed in the Wireshark interface list.

Software versions: Windows 10 Pro 64 bit, Python 3.8, Wireshark 3.2.3, nRF Connect 3.3.3, Sniffer 3.0.0.

I programmed the dongle with hex image: sniffer_pca10031_129d2b3.hex. The toolbar shows up in Wireshark, but not the sniffer interface:

I tried the nrf_sniffer_ble.bat --extcap-interfaces command, and that seems to work fine.

Is there anything else I can try?

Hi Han, 

Could you try other USB ports and do the Vidar's suggestion again?

Sorry for the delay. I tried, but the problem remains.

Do you have an idea about the difference between the BLE app and the programmer where it comes to communicating with the device. Could it be that the programmer bypasses the COM port emulator and talks directly to the USB?

 As your thought, the programmer app communicates through the Jlink interface while the BLE app communicates through the VCOM.

You could try to run nRF connect as admin since the error says "access denied", and also check if the JLink COM port is listed in the "Device manager".

The 'JLink CDC UART Port (COM3)' is listed in the Device Manger.

Running as Admin doesn't change the outcome.

It seems to me that there is a problem with the virtual COM port on this specific PC, as the software runs on other PCs. The same problem occurs with unrelated software, so I think it's fair to close this case.
