For the V2 firmware, its recommended that you use Wireshark - the V1 had various methods such as a Python API but really they were all mediocre compared to the abilities of Wireshark
Install Wireshark
Start by installing Wireshark, a great cross-platform monitoring tool
Visit https://www.wireshark.org/ and download the latest version of Wireshark for your operating system
When installing on windows, check the box to also install WinPcap
WARNING this file is huge - over 200MB!

|
Open Wireshark, in the Help menu select About wireshark |
|
|
In the Folders tab, find the extcap path |
Open that directory up, then copy over the files within the nrf_sniffer.zip extcap folder into the extcap folder
In the end, your Wireshark/extcap directory should contain nrf_sniffer.bat, nrf_sniffer.py and SnifferAPI folder.
Now quit Wireshark so we can get things tested!
Dealing With Python 2 vs 3
Nordic's sniffer code is Python 2 only, so if you have Python 3 your default (which, by now, you probably do) you'll need to install Python 2.
The best way to test is to go to the extcap directory in your terminal software and try running nrf_sniffer.bat (Windows) or python nrf_sniffer.py (Mac/Linux)
If you get the error on the print "LOGGING FAILED" line
or the "No module named 'Logger'" error
Then you'll need to trick the sniffer software into using Python 2
For Windows, at least, I installed Python 2.7 into C:\Python27 (the default) and then edited the nrf_sniffer.bat file to say:
@echo off C:\Python27\python "%~dp0nrf_sniffer.py" %*
note the explicit path!
Installing Dependancies
Once you get past that part, you can try rerunning the bat/py script and you may get other missing module errors like No module named serial
You'll need to install these with pip
Warning! Because you have to use Python2 here, make sure you're using pip2 or on windows, use the full path C:\python27\Scripts\pip2.exe
e.g. C:\python27\Scripts\pip2.exe install pyserial
Eventually you'll get No arguments given! which means the script is, at least, fully running
Test Capture
OK finally once that works, start Wireshark again.
This time you'll see the nRF Sniffer capture device!
Double Click on that line to start the Capture!
