Amateur radio APRS daemon which listens for messages and responds
Project description
APRSD is a Ham radio APRS message command gateway built on python.
What is APRSD
APRSD is a python application for interacting with the APRS network and providing APRS services for HAM radio operators.
- APRSD currently has 4 main commands to use.
server - Connect to APRS and listen/respond to APRS messages
webchat - web based chat program over APRS
send-message - Send a message to a callsign via APRS_IS.
listen - Listen to packets on the APRS-IS Network based on FILTER.
Each of those commands can connect to the APRS-IS network if internet connectivity is available. If internet is not available, then APRS can be configured to talk to a TCP KISS TNC for radio connectivity.
Please read the docs to learn more!
APRSD Overview Diagram
Typical use case
APRSD’s typical use case is that of providing an APRS wide service to all HAM radio operators. For example the callsign ‘REPEAT’ on the APRS network is actually an instance of APRSD that can provide a list of HAM repeaters in the area of the callsign that sent the message.
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.

Web Admin Interface
To start the web admin interface, You have to install gunicorn in your virtualenv that already has aprsd installed.
source <path to APRSD's virtualenv>/bin/activate pip install gunicorn gunicorn --bind 0.0.0.0:8080 "aprsd.wsgi:app"
The web admin interface will be running on port 8080 on the local machine. http://localhost:8080
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 in the docker/ directory that can be used to run your container. To provide the container an aprsd.conf configuration file, change your docker-compose.yml as shown below:
volumes:
- $HOME/.config/aprsd:/config
To install plugins at container start time, pass in a list of comma-separated list of plugins on PyPI using the APRSD_PLUGINS environment variable in the docker-compose.yml file. Note that version constraints may also be provided. For example:
environment:
- APRSD_PLUGINS=aprsd-slack-plugin>=1.0.2,aprsd-twitter-plugin
