MeshCore/Channels

Channels are where the conversation happens. Think of them like group chats — anyone with the right device and scope set can join in. There is nothing stopping you creating your own, but the ones below are the agreed community channels so everyone knows where to find each other.

In the Scottish MeshCore network, what really matters for routing is region scope — not the channel name. The channel name is for people; the scope is for the mesh.

🏷️ Channel name and scope

A channel name and a region scope are related, but they are not the same thing.

For example:

Channel: #edinburgh
Scope:   edi

The channel name is what you see. The scope is what tells the mesh to carry your message through Edinburgh-area repeaters.

Joining a channel does not automatically set the scope.

Before sending, check the channel settings in the Companion App and make sure the scope matches where you want the message to travel.

📡 Current (2026) and proposed (2027 and beyond) channels

The following table lists known community channels and proposed channels for Scotland.

Type is documentation only; it is not a Companion App setting. It groups channels by how you pick them: Wide for large-footprint traffic (whether the scope is sco or ioi), Regional for Scottish region area channels, and Local for Scottish City / town / metropolitan areas. Set Scope to match the reach you want.

Channel	Type	Scope	Status	Use
#scotland	Wide	sco	Current	General Scotland-wide MeshCore traffic.
#ireland	Wide	ioi or sco	Current	General Island of Ireland traffic.
#norniron	Wide	ioi or sco	Current	Northern Ireland Traffic
#thenorf	Wide	eng-ne	Current	North East England traffic.
#northeast	Wide	eng-ne	Current	North East England traffic.
#highlands	Regional	hig	Current	Highlands traffic (currently used around Inverness).
#central	Regional	cen	Proposed	Central Scotland traffic.
#dundee	Local	dun	Proposed	Dundee area traffic.
#edinburgh	Local	edi	Proposed	Edinburgh area traffic.
#falkirk	Local	fal	Proposed	Falkirk area traffic.
#fife	Regional	fif	Current	Fife area traffic.
#glasgow	Local	gla	Proposed	Glasgow area traffic.
#perth	Local	per	Proposed	Perth area traffic.
#tayside	Regional	tay	Proposed	Tayside traffic.
#test	Wide	Set the scope being tested	Current	Test messages. Use sco, edi, gla, or another scope that matches what you are testing.

As of Summer 2026, The ScotMesh MC Mesh is still in its early growth phase. As such there is no pressing requirement to restrict in-country traffic to sub regions or local regions. In practical terms country wide traffic will not cause us any issues for at least another year, probably longer. So the country wide region sco will be enough until then.

Proposed channels are shared names the community is still settling on. They are listed here so that people can talk about the same idea using the same name and scope, rather than ending up with several competing versions.

🤔 Choosing the right channel in the future (2027 and beyond

Use the narrowest scope that still fits what you are sending. Examples:

#scotland / sco          Scotland-wide mesh (Current)
#edinburgh / edi         Local area (same idea for #glasgow/gla, #fife/fif, #dundee/dun, …)(Future)
#test / <scope>          Pick the scope you are actually testing (current)
#ireland / ioi or sco    Island of Ireland channel (pick scope for the path you want) (current)

👍 Good practice for the future expanded mesh

• Keep local traffic local where possible.
• Use #test for test messages so normal channels stay readable.
• Use Scotland-wide scope only when the conversation is relevant across Scotland.
• Use ioi when the message belongs on the Island of Ireland scope, or sco on #ireland when you want Scotland-wide scoped carriage (see Scopes).
• Wildcard forwarding will remain disable in the Scottish setup.
• New public channel names tend to land better when discussed with the community first.
• Always check the Companion App scope before sending — a wrong scope and your message goes nowhere useful.
