bluepy
Python interface to Bluetooth LE on Linux
This is a project to provide an API to allow access to Bluetooth Low Energy devices from Python. At present it runs on Linux only; I've mostly developed it using a Raspberry Pi, but it will also run on x86 Debian Linux.
The code is tested on Python 2.7 and 3.4; it should also work on 3.3.
There is also code which uses this to talk to a TI SensorTag (www.ti.com/sensortag).
An example to interface the Nordic Semiconductor ASA IoT Sensor Kit, Thingy:52 is available in thingy52.py (https://www.nordicsemi.com/eng/Products/Nordic-Thingy-52).
Installation
The code needs an executable bluepy-helper
to be compiled from C source. This is done
automatically if you use the recommended pip installation method (see below). Otherwise,
you can rebuild it using the Makefile in the bluepy
directory.
To install the current released version, on most Debian-based systems:
$ sudo apt-get install python-pip libglib2.0-dev
$ sudo pip install bluepy
If you find bluepy-helper
isn't being built, please try:
$ sudo pip install --no-binary :all: bluepy
before reporting any issues.
For Python 3, you may need to use pip3
:
$ sudo apt-get install python3-pip libglib2.0-dev
$ sudo pip3 install bluepy
To install the source and build locally:
$ sudo apt-get install git build-essential libglib2.0-dev
$ git clone https://github.com/IanHarvey/bluepy.git
$ cd bluepy
$ python setup.py build
$ sudo python setup.py install
I would recommend having command-line tools from BlueZ available for debugging. There are instructions for building BlueZ on the Raspberry Pi at http://www.elinux.org/RPi_Bluetooth_LE.
Documentation
Documentation can be built from the sources in the docs/ directory using Sphinx.
