Hi,
Recently I bought the Bluefruit LE Sniffer from a well-known distributor in the USA. More and more devices have Bluetooth Low Energy, so I think your LE sniffer is very convenient.
I downloaded the manual “introducing-the-adafruit-bluefruit-le-sniffer.pdf”, I followed the guidelines written in the manual.
But soon I found out that the sniffer isn’t visible in Wireshark, within Wireshark I can see the extcap folder including the files and API.
I changed the batch file in the extcap folder but no luck.
Below the version info.
• Wireshark 3.4.8
• Silicon Laboratories 6.7.0.0 USB Driver
• Windows7 Professional 32 bit
• nrf_sniffer_for_bluetooth_le_4.0.0.zip
• Bluefruit LE Sniffer FIRWARE V2
I also tried on Window10 64 bit but nothing has changed so far, so what do I have to do to make the LE Sniffer visible (working) in Wireshark?
Kind regards,
Martin Boere

Re: Bluefruit LE Sniffer operation
Hi,
you should always use the extcap folder belonging to your firmware version. If you have v2 on your device, use the extcap from here https://learn.adafruit.com/introducing- ... sniffer-v2
If this doesn't work and you have a J-Link by hand check your firmware version. My board was sold as firmware v2 but had firmware v1 flashed.

Re: Bluefruit LE Sniffer operation
Hi,
I already changed the folder you refer to, but that’s for Python by the way and I use Windows.
I have no J-Link so I can’t check the Firmware version of your BLE sniffer, but It still isn’t visible in Wireshark.
Kind regards,
Martin

Re: Bluefruit LE Sniffer operation
Hi,
use this guide: https://learn.adafruit.com/introducing- ... sniffer-v2
make sure the device is visible in device manager (COM&LPT)
install Wireshark 2.9.0: https://2.na.dl.wireshark.org/win64/all-versions/
install Python 2.7.x
install pyserial (open cmd, C:\python27\Scripts\pip2.exe install pyserial)
download extcap_2.0.0beta1.zip (don't know why it is no longer available at Adafruit.com)
copy extcap folder to c:\Program Files\Wireshark\
open cmd in extcap folder, execute nrf_sniffer.bat --extcap-interfaces
look for errors
start Wireshark
look for errors in c:\Users\%username%\AppData\Roaming\Nordic Semiconductor\Sniffer\logs\log.txt

Re: Bluefruit LE Sniffer operation
Hi,
I followed your steps for install and that was successful. But I can’t find the file c:\Users\%username%\AppData\Roaming\Nordic Semiconductor\Sniffer\logs\log.txt, I that particular folder there is no such file.
Kind regards,
Martin

Hi,
When I execute the batch file “nrf_sniffer_ble.bat”, I get an error message in Wireshark itself.
Please refer to the attachment

Re: Bluefruit LE Sniffer operation
Hi,
you are still using extcap from v4.0.0, this won't work.
You have to use extcap from v2.0.0beta1.
again: execute "nrf_sniffer.bat --extcap-interfaces"

Hi,
I changed to extcap folder and now It works! (Please refer to attachment). I changed the folder before but that was without the Python installation.
Thanks a lot!
Kind regards,
Martin
