APRS Assistant

An LLM-based assistant for the Automatic Packet Reporting System (APRS).

Note: This library provides core functionality for an LLM-based APRS chatbot, but does not itself directly handle APRS messaging (RX, or TX). For this, a library like apsd is needed. Instructions for connecting the assistant to the APRS network are forthcoming in a future update.

Installation

pip install aprs-assistant

Callsign

Your bot needs a callsign! Set with the APRS_ASSISTANT_CALLSIGN environment variable.

export APRS_ASSISTANT_CALLSIGN=<CLEVER_CALLSIGN>

API Keys

At a minimum, this library requires setting an OpenAI API key. Bing and APRS.fi API keys are also used to support various tools and services. Set the, as environment variable in bash, as follows:

export OPENAI_API_KEY=<YOUR_KEY>
export BING_API_KEY=<YOUR_KEY>
export APRSFI_API_KEY=<YOUR_KEY>

Running Local Chat

The library supports local chats (e.g., for debugging) as follows:

python -m aprs_assistant <YOUR_CALLSIGN>

Type exit or press Ctrl-D to exit.

FCC ULS Integration

APRS Assistant supports basic callsign lookups using a local copy of the FCC ULS database. This database is about 325 MB and is easily created.

cd ./tools/parse_fcc_uls
bash create_db.bash
cd ../..
mkdir data
mv ./tools/parse_fcc_uls/fcc_uls.db data/.

This step only needs to be done once (or when you wish to update the database with new records!)

See ./tools/parse_fcc_uls/README for more details.

Integration

To integrate aprs-assistant into your application, simply use:

from aprs_assistant import generate_reply

sender_callsign = "NOCALL"
message = "What's the weather?"
response = generate_reply(sender_callsign, message)

print(response)

Note: response can be None
