open-packet 1.0.0

Amateur radio packet messaging client

open-packet

An open-source packet messaging client for amateur radio operators.

Early development: v0.1 — expect breaking changes between releases.

---

Quickstart

Requirements:

• Linux (Windows and MacOS are currently untested, but should probably work)
• Python >= 3.11
• A KISS-capable TNC connected via TCP or serial port. If you don't have hardware, Direwolf is a good software TNC.

Install:

uv tool install git+https://github.com/loredous/open-packet

Configure:

Create ~/.config/open-packet/config.yaml:

connection:
  type: kiss_tcp          # kiss_tcp | kiss_serial
  host: localhost         # TCP only
  port: 8001              # TCP only

Run:

open-packet

On first launch, you'll be prompted to enter your callsign and BBS node details. You can update these later via the Settings screen (s).

How It Works

open-packet connects to a BBS node over AX.25 packet radio via a KISS TNC, syncing your personal messages and bulletins to a local SQLite database. The core engine is interface-agnostic — the terminal client is the first frontend, with a web client and other interfaces planned.

Configuration

The config file lives at ~/.config/open-packet/config.yaml (or pass a custom path as the first argument to open-packet).

connection:
  type: kiss_tcp          # kiss_tcp | kiss_serial
  host: localhost         # TCP only
  port: 8001              # TCP only
  # device: /dev/ttyUSB0  # serial only
  # baud: 9600            # serial only

store:
  db_path: ~/.local/share/open-packet/messages.db    # SQLite message database
  export_path: ~/.local/share/open-packet/export     # flat-file export directory

ui:
  console_visible: false       # show AX.25 frame console on startup
  console_buffer: 500          # number of lines to keep in the console ring buffer
  # console_log: ~/.local/share/open-packet/console.log  # log frame traffic to file (omit to disable)

Operator identity (callsign, SSID) and BBS node configuration are managed interactively through the TUI rather than in the config file. Access them via the Settings screen (s).

Development

# Clone and install dependencies
git clone https://github.com/loredous/open-packet.git
cd open-packet
uv sync

# Run the app
uv run open-packet

# Run tests
uv run pytest

# Run with Textual's dev tools (live reload + DOM inspector)
# Note: this launches OpenPacketApp directly, bypassing main() — config loads from the default path
uv run textual run --dev open_packet/ui/tui/app.py
