Bluefruit LE Sniffer (nRF51822) - Not displaying in Wireshark 4.0.4 (Windows 11)

Post by jasongendron »

Hi,

I have a Bluefruit LE Sniffer (Product ID: 2269) (Order 3045363-3618647992). I've followed all steps in the Introducing the Adafruit Bluefruit LE Sniffer guide, but I cannot get the device to display in Wireshark as a capture interface. I'm running the following software versions:
  • Windows 11 22H2
  • Wireshark v4.0.4
  • Silicon Labs VCP driver v6.7.6
  • Python v3.11.3 (with pyserial library installed)
  • nRF Sniffer Plugin v4.1.1
The CP2104 displays correctly in Device Manager (Silicon Labs CP210x USB to UART Bridge) and has a COM port assigned. The Wireshark plugin also appears to be loading correctly, as I can view its toolbar by selecting (View > Interface Toolbars > nRF Sniffer for Bluetooth LE). I attempted to connect to the device via PuTTY (460800 baud, RTS/CTS flow control), but there is no data output. I also don't see any LED activity on the board, but not sure if that is expected.

In order to validate extcap plugin functionality, I ran (as admin):

Code: Select all

nrf_sniffer_ble.bat --extcap-interfaces
The output was as follows:

Code: Select all

extcap {version=4.1.1}{display=nRF Sniffer for Bluetooth LE}{help=https://www.nordicsemi.com/Software-and-Tools/Development-Tools/nRF-Sniffer-for-Bluetooth-LE}

value {control=1}{value=1}{display=Legacy OOB data}
value {control=1}{value=2}{display=Legacy LTK}
value {control=1}{value=3}{display=SC LTK}
value {control=1}{value=4}{display=SC Private Key}
value {control=1}{value=5}{display=IRK}
value {control=1}{value=6}{display=Add LE address}
value {control=1}{value=7}{display=Follow LE address}
It appears that the device is not displaying in the extcap interfaces list. I tried reinstalling all related software and drivers, but I can't get it to show.

Thanks!
Jason

Hey, sorry for the delay. Let's go ahead and just send a replacement to try out. If two do the same thing, we can look into this further. There are a lot of bits and pieces that have to all work together, but there's nothing obviously missing from what you've provided.

I'll let support know to send a replacement. You can also link them to this thread again in another email if you want.
