Looking for MeshCore or Meshtastic? They have their own wiki at wiki.scotmesh.uk →

A free, encrypted network for Scotland that anyone can join.

Reticulum carries messages, chat, files and pages over the internet and over LoRa radio, and keeps working when the things underneath it do not. Connecting takes about five minutes.

Welcome. ScotMesh runs the Reticulum backbone for Scotland and writes this wiki; you are very welcome to use both, and to add to either. Whether you have never heard of Reticulum or you want to put a solar relay on a hill, there is a page here for you. Pick where you are:

I just want to try it

Install one app, type in one address, and you are on the network with everyone else: messaging, chat, files and pages.

Connect in five minutes →

Then First steps: say hello in the chat room and send your first message.

I want to understand it first

No addresses to configure, no accounts, no company in the middle. Reticulum is unusual, and it is worth knowing why.

What Reticulum is →

Then How Reticulum works, How it compares with Meshtastic and MeshCore, and the Glossary.

I want to put a radio on air

A LoRa board becomes a Reticulum radio for your laptop or phone, or a self-contained relay you can look after from home.

Flash a board →

Then ScotMesh firmware for solar and hilltop relays, and Antennas and siting for making it reach.

The backbone right now

Live from the node itself, the same feed as rns.scotmesh.net, refreshed every two minutes. If the strip is blank or says unknown, treat the backbone as unconfirmed and check the node page directly.

Live backbone status: rns.scotmesh.net/status

Connect now

The backbone is a public Reticulum transport node in Dalgety Bay, Fife. Anyone may connect, there is nothing to register, and it costs nothing.

Out of the box: install MeshChatX (Windows, macOS, Linux, Android), Sideband (Android, Windows, macOS, Linux) or an iPhone app, add a connection of type TCPClientInterface with host rns.scotmesh.net and port 4242, and you are on. Step by step.

Full installation: add this to your Reticulum config:

  [[ScotMesh Backbone]]
    type = TCPClientInterface
    enabled = yes
    target_host = rns.scotmesh.net
    target_port = 4242

Behind CGNAT or a firewall you do not control? Use the I2P entry point instead; no port needs forwarding at either end. See Access over I2P.

Got a LoRa radio? ScotMesh's first gateway is on air in Fife, carrying both profiles below and linked to the backbone, and standalone solar nodes are going out. Coverage is small so far, so a radio built anywhere in Scotland will hear the others as they arrive. Every radio must match all five settings exactly: a board with a different spreading factor is not weakly connected, it is completely deaf, and nothing reports an error. The 868 profile moved from 867.5 to 869.4625 MHz on 11 September 2026 (Ofcom's 869.40–869.65 MHz sub-band), so retune any radio still on the old frequency. rnode.scotmesh.net applies either profile in one click.

	ScotMesh 433	ScotMesh 868
Frequency	433.775 MHz	869.4625 MHz
Bandwidth	125 kHz	125 kHz
Spreading factor	8	9
Coding rate	4/5	4/5
TX power	7 dBm	22 dBm

Whichever way in you chose: restart Reticulum, then check the interface shows Up (in rnstatus, or on the app's interfaces page). If it does not, Troubleshooting lists the usual causes.

What runs on the backbone

Once connected, these are the addresses to paste into your client. Each one is explained in The ScotMesh Backbone; Services and addresses has them all in one place.

Service	Address	Use it with
TCP entry point	rns.scotmesh.net:4242	Any Reticulum client
I2P entry point	a3pswrtvpuro62ijhb7lwdt2n6aqgajglof27ynbonynmolzlz7q.b32.i2p	Any Reticulum client, via i2pd
Chat hub (RRC), room scotmesh	004e5a15da221d9a236b0e8d74195f13	MeshChatX, rrc clients
LXMF propagation node	c283b754e0acc11ce48d2f5e29167e0c	Sideband, MeshChatX, Nomad Network
Nomad Network node	10a839df2c50635bcb0c8a299b9ca0f8	Nomad Network, MeshChatX
Transport instance	20b962cd814444f7812e409e7c47f319	Shows up in rnpath and node maps

The node peers outward to rebelnet.uk, rns.cybercore.uk and rmap.world, so a client connected here can reach the rest of the public Reticulum network. See Who we peer with.

Where the network is

Where things actually are, rather than where we would like them to be. Updated by hand as things land.

	Milestone	Notes
✔	Reticulum backbone online	Public transport node at rns.scotmesh.net:4242, peered into the wider network.
✔	Reachable over I2P	No port forwarding needed at either end.
✔	Chat hub running	RRC hub with the scotmesh room.
✔	Propagation node running	Offline message delivery for the region.
✔	Web flasher for RNodes and nodes	rnode.scotmesh.net, with both ScotMesh profiles built in.
✔	LoRa gateway on air	First gateway in Fife, both profiles, linked to the backbone.
✔	Standalone solar nodes	ScotMesh firmware: managed and updated over the mesh. First units on the bench and going out.
✘	Coverage beyond Fife	Needs gateways and relays elsewhere. Put one up and tell us.

Say hello

ScotMesh is a community, not a company. Most of us are on the ScotMesh Discord, the quickest place to ask anything, Reticulum or not, and there is also the forum at scotmesh.uk; the chat room is where to find us on the network itself; and About ScotMesh says who we are and what we run. If a page here is wrong or unclear, say so, or fix it: anyone can ask for an editing account.
