Python API for Bluefruit LE Sniffer
This repository contains the Python API for Adafruit's Bluefruit LE Sniffer, and our easy to use API wrapper.
It has been tested on the following platforms using Python 2.7:
- OSX 10.10
- Windows 7 x64
- Ubuntu 14.04

Sniffer Python Wrapper
Running sniffer.py in this folder on the Bluefruit LE Friend Sniffer Edition board will cause the device to scan for Bluetooth LE devices in range, and log any data from the selected device to a libpcap file (in
logs/capture.pcap) that can be opened in Wireshark.
The current example does not enable live streaming of data directly into Wireshark via named pipes since this would require a pre-compiled utility for each platform, but it should be possible to implement this on your platform if required.
To use sniffer.py, simply specify the serial port where the sniffer can be found (ex.
COM14 on Windows,
/dev/tty.usbmodem1412311 on OS X,
/dev/ttyACM0 or Linux, etc.):
python sniffer.py /dev/tty.usbmodem1412311
Note: You will need to run python with
sudo on Linux to allow the log file to be created, so
sudo python sniffer.py /dev/ttyACM0, etc..
This will create a new log file and start scanning for BLE devices, which should result in the following menu:
$ python sniffer.py /dev/tty.usbmodem1412311 Logging data to logs/capture.pcap Connecting to sniffer on /dev/tty.usbmodem1412311 Scanning for BLE devices (5s) ... Found 2 BLE devices:  "" (14:99:E2:05:29:CF, RSSI = -85)  "" (E7:0C:E1:BE:87:66, RSSI = -49) Select a device to sniff, or '0' to scan again >
Simply select the device you wish to sniff, and it will start logging traffic from the specified device.
Type CTRL+C to stop sniffing and quit the application, closing the libpcap log file.
NOTE: You may need to remove the sniffer and re-insert it before starting a new session if you see any unusual error messages running sniffer.py.
This Python script was written and tested on Python 2.7.6, and will require that both Python 2.7 and pySerial are installed on your system.
