Workshop

Off the grid: build an app that runs over radio on Reticulum (LoRa).

This is the confirmed camp workshop. Write software that survives without the internet — Reticulum carries it over LoRa, packet radio, or anything else that moves data: every node self-identifies, every packet is encrypted and authenticated, no servers, no IP, no DNS.

In the hour we build a small application together and run it over real LoRa hardware on site, inside the EU 868 MHz duty cycle. We cover the core primitives — identity, destination, link, resource — plus LXMF for store-and-forward messaging, and how to expose a service other nodes can discover and reach. Working examples are in Python; the patterns translate directly to Rust or C. What you build can also be served over the Freifunk wifi, or the internet, after the session.

The classic shape is a tiny web-style app — pages served over encrypted mesh links with no internet at all, via Nomad Network:

pip install rns nomadnet
rnsd        # bring up the stack (writes ~/.reticulum/config)
nomadnet    # host and browse pages over Reticulum

Bring a laptop. Some programming experience assumed; no radio background needed. Devices and radios are available on site from €20. Time and room: see the Agenda — accepted, not yet scheduled.

Reticulum is educational / workshops only and does not bridge to Meshcore or Meshtastic.

Session confirmed for DWeb Camp Berlin 2026. Verified 2026-06-16 against the Reticulum / Nomad Network projects.
