About

=====

Concise example to test the behavior of MicroPython's ``umqtt.simple`` against

Mosquitto 2.0.11 / 2.0.12.

The reason is to investigate a potential regression with Mosquitto 2.0.12,

being more strict wrt. protocol compliance, which apparently breaks

``umqtt.simple``.

- https://github.com/micropython/micropython-lib/issues/445

- https://github.com/hiveeyes/terkin-datalogger/pull/97

Notes

=====

There is a module ``umqtt.universal``, which is derived from ``umqtt.simple``.

It is compatible with both MicroPython and CPython.

Setup

=====

Install MicroPython::

    brew install micropython

Acquire sources::

    git clone https://github.com/daq-tools/umqtt-example

    cd umqtt-example

Usage

=====

Run Mosquitto::

    # Version 2.0.11

    docker run -it --rm --publish=1883:1883 eclipse-mosquitto:2.0.11 mosquitto -c /mosquitto-no-auth.conf

    # Version 2.0.12

    docker run -it --rm --publish=1883:1883 eclipse-mosquitto:2.0.12 mosquitto -c /mosquitto-no-auth.conf

Invoke tests, on both CPython and MicroPython::

    make test

In order to individually invoke the tests, run::

    # CPython

    make test-cpython

    # MicroPython

    make test-micropython
