Reticulum is a mesh networking protocol that can use a wide variety of interfaces – LoRa using RNode, AX.25, WiFi, or tunnelled over IP. It puts a heavy emphasis on cryptography. It is written in Python so needs a general purpose computer to run.

It claims ~300 bytes to establish a link and 0.44bps to maintain it. It seems to be link oriented but has a “group” destination type using a pre-shared key and a “plain” destination type using no key.

• LXMF - A message format containing: content, to, from, and dictionary fields, used by Reticulum.
• Sideband - a messenger app that sends LXMF messages over Reticulum.
• Looks like console equivalent of Sideband
