Python CoAP library

Project Description

aiocoap -- The Python CoAP library

The aiocoap package is a Python implementation of CoAP, the Constrained
Application Protocl (`RFC 7252`_, more info at

It uses the asyncio module introduced in Python 3.4 to facilitate concurrent
operations while maintaining a simple to use interface and not depending on
anything outside the standard library.

aiocoap is originally based on txThings_. If you want to use CoAP in your
existing twisted application, or can not migrate to Python 3 yet, that is
probably more useful to you than aiocoap.

For details on how to usethe aiocoap library, have a look at the :mod:`aiocoap`
module documentation, or at the :doc:`examples` and :doc:`tools` provided.

All examples can be run directly from a source code copy. If you prefer to
install it, the usual Python mechanisms apply.


aiocoap tries to stay close to PEP8_ recommendations and general best practice,
and should thus be easy to contribute to. Unit tests are implemented in the
``./tests/`` directory; complete test coverage is aimed for, but not yet
complete (and might never be, as the error handling for pathological network
partners is hard to trigger with a library designed not to missbehave).

Documentation is built using sphinx_; hacks used there are described in

Bugs from design goal and wishlist to typos are currently tracked in github
(see below).
