Using the Firmware V1 Sniffer
There are currently two ways to use the sniffer:
Nordic's nRF Sniffer Utility (Windows only)
If you are on Windows, the best user experience will be had by using the official Nordic nRFSniffer application, available as a download from Nordic Semiconductors after creating a 'My Pages' account, and registering your device using the product ID located on the Bluefruit LE Sniffer packaging.
Python API (Cross-Platform, no Registration)
If you are not using Windows, or don't wish to create a MyPages account, the alternative is to use a Python interface to communicate with the nRFSniffer firmware, which will log any traffic to a libpcap file that can be opened directly in Wireshark. This has been tested on OS X 10.10, Ubuntu 14.04 and Windows 7, but it currently doesn't support streaming data directly into Wireshark via named pipes (though this is possible with some platform-specific effort).
