ABle (Allthenticate's Bluetooth Low Energy (Library)) is a platform agnostic python framework for communication with centrals as a BLE Peripheral with simple yet powerful 'BLE Sockets'

Project description


Imports: isort Code style: black Type checking: mypy

Able stands for Allthenticate's BLE Peripheral Library. It serves the purpose of enabling the abstraction of using a BLE Peripheral on Ubuntu, MacOs and Windows based systems without having to adapt your software to have platform specific support.

In Progress

Note that this project is still undergoing work by the development team, the main things we are working on are:

  • Cleaning up some bugs in the bluezdbus and macos backend
  • Making the gitlab/github repo public for contributions
  • Setup a slack for developers to reach out to us about issues or ideas
  • Make logging/use clearer and update our documentation (for example we require a fork of bluez) and moving things from this readme to our docs
  • Get our docs on read the docs
  • Some more surprises :)

How To's

Quick Start

To get started just run This will install poetry and all of the project's dependencies, and drop you into the projects virtual environment.


Whenever you pull new updates we recommend running a quick poetry install to get any updates. From there, please check out our examples to get started with the project!

Upgrading Poetry Installer

It may be the case that the current version of your Poetry package is outdated. Run scripts/ to check if there is a newer version of the poetry installer.

bash scripts/


Writing Docs

We follow the Sphinx docstring format for our docstrings, see the following site on the complete specification, but the general docstring will look like:


:param [ParamName]: [ParamDescription], defaults to [DefaultParamVal]
:type [ParamName]: [ParamType](, optional)
:raises [ErrorType]: [ErrorDescription]
:return: [ReturnDescription]
:rtype: [ReturnType]

Generating Docs

To generate the docs for local use you should just have to run the following inside of the poetry shell:

make html

Then open the html produced by Sphinx.

Auto-Generating Docs

If you want to have docs magically update as you are writing them, run the following command:

sphinx-autobuild source/ build/html/

Testing Able

How To Test?

Running tests are easy, you need to only do a few things as a developer. First track down the IP of the companion you plan to be using, we recommend a raspberry pi. Once you have that IP, export it as an environment variable as so:


Now, we can run the tests with the following command:

poetry install && poetry run pytest tests

Rigorous Testing

If you want to do more rigorous testing over a long period of time and check for flaky tests, you will have to modify the pyproject.toml. We already have the dependencies you need to run tests multiple times to detect flakiness, all you need to do is modify the following line:

addopts = "--flake-finder --flake-runs=1 --reruns 5 --reruns-delay 5"


addopts = "--flake-finder --flake-runs=10 --reruns 5 --reruns-delay 5"

This will run each test 10 times, you can even modify it to be greater should you choose. You can also modify the reruns and reruns-delay parameters to change how much time you should wait between failed tests, maybe to let things simmer and how many reruns you will accept.

Speedy Tests

Our dependencies include pytest-fast-first which will locally track which tests are quicker and will use AI and deep learning (a json dictionary of times) to track and run tests that go faster first! Neat!

Coming Soon To Testing

We are hoping to have unit tests coming soon for Able but right now are relying solely on hardware in the loop tests to get things off the ground. Eventually we will detect if you have a companion set and if not, we will only run the unit tests.


If you have any questions on the use of this library feel free to reach out the head maintainer or submit an issue on the repository.


Contributing is not currently enabled but once the repository is licensed we will be opening the project up for public contributions.


This project was inspired by the great work done by the developer team for Bleak which is a fantastic platform agnostic bluetooth framework for a BLE client/central we would highly reccomend!

We also took notes from the work done by Kevin Car with his companion library Bless, who made a great server supplement to Bleak whose work saved us from countless hours from fighting dbus and pyobjc!
