There are a couple of other python 3 ports out there; futurize does 90% of the work and some bytes/bytearray work covers most of the rest. This one exists mostly as a place to hang an explanation of why, if you're having trouble with it, it's not actually anything wrong with btaps itself...
However - if you're trying to use this code in Ubuntu 22.04, and especially if you're getting "Bad address" problems (or if you get as far as using strace, seeing EFAULT problems) it turns out that the version of pybluez (0.23-4build1) that shipped in ubuntu 22.04 had just missed python started to enforce use of size_t instead of int and failed outright with
- ::
- SystemError: PY_SSIZE_T_CLEAN macro must be defined for '#' formats
0.23-5 in 22.10/kinetic has some early fixes, cherry picked from Debian - but they were incomplete.
The right thing to do is grab pybluez 0.30 or later, those appear to have cleaned this up (but are not yet in ubuntu, as of kinetic.) If you need to patch together something (or that's just easier for you), apt-get source and look at pybluez-0.23/bluez/btmodule.c; every place you find a PyArg_ParseTuple that takes an &len parameter, look for the misdeclaration of that len as int and change it to Py_ssize_t. I believe just changing sock_send and sock_sendall were enough to get this package working; if you need more than that, go for 0.30 or later instead.

This project is a library and command-line interface for communicating with and programming a Plugable PS-BTAPS1 Bluetooth Home Automation Switch.
- libbtaps.py
- Serves as a Python implementation of the BTAPS protocol, either to be used directly in your programs, or to be used as a reference in developing your own implementation in a different language.
- btaps.py
- A simple command-line UI that implements all the features exposed by libbtaps.py.
USAGE: python btaps.py [Bluetooth address] EXAMPLE: python btaps.py 00:00:FF:FF:00:00
- The following functions of the Plugable PS-BTAPS1 are currently present in the library:
- Setting Switch On/Off
- Reading current status of switch (name, on/off state, timer settings)
- Creating, modifying and deleting timers
- Changing the device's name
- Updating the device's date and time to your PC's current date and time
- The following features and items are still to come:
- NFControl (Device proximity on/off functionality)
- Security PIN
- Better error handling
- Better documentation
- Mac OS X support
Due to PyBluez limitations, this library will currently only work on Linux and Windows systems.
First, install PyBluez using the appropriate link or command for your OS:
- Windows
- Download and install PyBluez for Python 2.7
Ubuntu/Debian:
sudo apt-get install python-bluez
Fedora:
sudo yum install pybluez
Arch:
sudo pacman -S python2-pybluez
Then, simply pip install our module::
pip install plugable-btaps
Find some usage examples and documentation for libbtaps in our GitHub Wiki
- When I try to pip install plugable-btaps I get a compilation error:
- This means that you have not installed PyBluez and pip is trying to compile PyBluez from source, but you don't have the necessary compilation dependencies installed on your system. Install PyBluez as outlined above.
