APRSD - Ham radio APRS-IS Message plugin server
KM6LYW and WB4BOR
APRSD is a Ham radio APRS message command gateway built on python.
APRSD listens on amateur radio aprs-is network for messages and respond to them. It has a plugin architecture for extensibility. Users of APRSD can write their own plugins that can respond to APRS-IS messages.
You must have an amateur radio callsign to use this software. APRSD gets messages for the configured HAM callsign, and sends those messages to a list of plugins for processing. There are a set of core plugins that provide responding to messages to check email, get location, ping, time of day, get weather, and fortune telling as well as version information of aprsd itself.
Please read the docs to learn more!
APRSD Overview Diagram
Typical use case
Ham radio operator using an APRS enabled HAM radio sends a message to check the weather. An APRS message is sent, and then picked up by APRSD. The APRS packet is decoded, and the message is sent through the list of plugins for processing. For example, the WeatherPlugin picks up the message, fetches the weather for the area around the user who sent the request, and then responds with the weather conditions in that area. Also includes a watch list of HAM callsigns to look out for. The watch list can notify you when a HAM callsign in the list is seen and now available to message on the APRS network.

Commands
Configuration
This command outputs a sample config yml formatted block that you can edit
and use to pass in to aprsd
with -c
. By default aprsd looks in ~/.config/aprsd/aprsd.yml

Development
git clone git@github.com:craigerl/aprsd.git
cd aprsd
make
Workflow
While working aprsd, The workflow is as follows:
Checkout a new branch to work on by running
git checkout -b mybranch
Make your changes to the code
Run Tox with the following options:
tox -epep8
tox -efmt
tox -p
Commit your changes. This will run the pre-commit hooks which does checks too
git commit
Once you are done with all of your commits, then push up the branch to github with:
git push -u origin mybranch
Create a pull request from your branch so github tests can run and we can do a code review.
Release
To do release to pypi:
Tag release with:
git tag -v1.XX -m "New release"
Push release tag:
git push origin master --tags
Do a test build and verify build is valid by running:
make build
Once twine is happy, upload release to pypi:
make upload
Docker Container
Building
There are 2 versions of the container Dockerfile that can be used. The main Dockerfile, which is for building the official release container based off of the pip install version of aprsd and the Dockerfile-dev, which is used for building a container based off of a git branch of the repo.
Official Build
docker build -t hemna6969/aprsd:latest .
Development Build
docker build -t hemna6969/aprsd:latest -f Dockerfile-dev .
Running the container
There is a docker-compose.yml file that can be used to run your container. There are 2 volumes defined that can be used to store your configuration and the plugins directory: /config and /plugins
If you want to install plugins at container start time, then use the environment var in docker-compose.yml specified as APRS_PLUGINS Provide a csv list of pypi installable plugins. Then make sure the plugin python file is in your /plugins volume and the plugin will be installed at container startup. The plugin may have dependencies that are required. The plugin file should be copied to /plugins for loading by aprsd
