Simple Management Protocol (SMP) Client

smpclient implements the transport layer of the Simple Management Protocol. This library can be used as a dependency in applications that use SMP over serial (UART or USB), Bluetooth (BLE), or UDP connections. Some abstractions are provided for common routines like upgrading device firmware.

If you don't need a library with the transport layer implemented, then you might prefer to use smp instead. The SMP specification can be found here.

If you'd like an SMP CLI application instead of a library, then you should try smpmgr.

Install

smpclient is distributed by PyPI and can be installed with poetry, pip, and other dependency managers.

Development Quickstart

Assumes that you've already setup your development environment.

1. activate envr, the environment manager for bash, zsh, and PS:

   . ./envr.ps1

2. run poetry install when pulling in new changes
3. run lint after making changes
4. run test after making changes
5. add library dependencies with poetry:

   poetry add <my_new_dependency>

6. add test or other development dependencies using poetry groups:

   poetry add -G dev <my_dev_dependency>

7. run tests for all supported python versions:

   tox

Development Environment Setup

Install Dependencies

• python >=3.8, <3.13
• poetry: https://python-poetry.org/docs/#installation

Create the venv

poetry install

The venv should be installed to .venv.

Activate envr

envr supports bash, zsh, and PS in Linux, MacOS, and Windows. If you are using an unsupported shell, you can activate the .venv environment manually, use poetry run and poetry shell, and refer to envr-default for useful aliases.

. ./envr.ps1

Verify Your Setup

To verify the installation, make sure that all of the tests are passing using these envr aliases:

lint
test

Enable the githooks

The pre-commit hook will run the linters but not the unit tests.

git config core.hooksPath .githooks
