MSF CLI

The MSF CLI tool is designed for creating and managing projects using the MicroPython Sniffs Framework (MSF). You can find the framework repository here: https://github.com/surdouski/micropython-sniffs-framework.

Installation

pipx install msf-cli

Usage

Note: Note: Docker must be installed and available in your system path for broker commands to function.

new

msf new <path>               # creates new msf project at <path>

The new command initializes a new project at <path>. It provides a convenient setup for starting development, including essential configuration files such as .config/mqtt_as.json, with default settings (note: updating the "server" field is necessary). Additionally, the framework and required dependencies are installed.

Example directory structure after running this command:

Once configuration is updated, you can uncomment relevant code in main.py to test the device and settings setup. To run this, navigate to the project path, execute mpbridge dev a0, wait for initialization, press <Enter>, then press <Ctrl+D> for a soft restart to execute main.py.

install

msf install <package>

This command installs a MicroPython package to the "lib" directory in the current working directory, creating "lib" if it does not exist. Package names follow the syntax expected by mpremote.

Examples:

msf install pathlib
msf install github:surdouski/micropython-sniffs

broker

msf broker up --port=1883    # starts a local MQTT broker for testing (--port is optional, default is 1883)
msf broker down              # stops the local MQTT broker

up

msf broker up
# output: Local MQTT broker started at 192.168.x.x:1883.

This command sets up a local MQTT broker for testing within your network. If you have an existing broker, feel free to use it instead.

The command launches an eclipse-mosquitto:1.6 Docker container with default settings. You can use the optional --port parameter to specify a custom port. The command will output your local network IP and port information for connection.

down

msf broker down

Stops and removes the MQTT broker container.

devices

Device configurations and secrets can be passed as environment variables on the command line:

MQTT_DEVICES_TOPIC=test/devices msf devices <cmd>

Alternatively, you can specify configurations in two files: .config and .secrets.

.config

MQTT_DEVICES_TOPIC=topic/path/to/devices

.secrets

MQTT_SERVER_HOST=localhost
MQTT_SERVER_PORT=1883
MQTT_SERVER_USER=myuser  # optional
MQTT_SERVER_PASS=mypass  # optional, but required if user is specified

list

# list devices
msf devices

get device

# list settings for a device
msf devices <device_id>

get device setting

# show a specific setting
msf devices <device_id> <setting_id>

set device setting

# update the value of a setting
msf devices <device_id> <setting_id> [--set]/[-s] <value>

Tests (Development)

A test harness for this project is planned for future inclusion in workflows.
