This repository contains the Python API for Nordic's BLE Sniffer, and easy to use sniffer tool.
- Live capture on Windows, Linux, and OSX.
- Auto-start Wireshark in live mode
- Supports Wireshark 2.x using Lua dissector
- Python 3 support (not stable yet)
It has been tested on the following platforms using Python 2.7:
- Windows 10 x64
- Ubuntu 16.10
- OSX 10.10
- Seeed Tiny BLE ≈ $14
- Bluefruit LE Sniffer ≈ $30
- RedBear BLE Nano Kit ≈ $33
- Other nRF51 Dev Kits
Running sniffer.py in this folder 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.
Please specify the serial port where the sniffer can be found (ex. COM14 on Windows, /dev/tty.usbmodem1412311 on OSX, /dev/ttyACM0 on Linux):
python sniffer.py /dev/ttyACM0
You can also start Wireshark in live capture mode:
python ./sniffer.py --pipe /dev/ttyACM0
This will create a log file and start scanning for BLE devices, which should result in the following menu:
$ python sniffer.py /dev/ttyACM0
Logging data to logs/capture.pcap
Connecting to sniffer on /dev/ttyACM0
Scanning for BLE devices (5s) ...
Found 2 BLE devices:
[1] "" (14:99:E2:05:29:CF, RSSI = -85)
[2] "My device" (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.
This Python script will require that both Python 2.7 and pySerial are installed on your system. For Windows live capture support, you need to install PyWin32.
- The sniffer board may need to be re-inserted before starting a new session.
- You may need to run python with
sudoon Linux. - On Windows, if you have both python2 and python3 installed, you may need to run with
py -2 sniffer.py ...command. - The list of known issues is here
