Set your node up following the [https://meshtastic.org/docs official Meshtastic docs], with the settings below for the Scottish mesh.

== Radio ==
{| class="wikitable"
! Setting !! Value
|-
| Region || <code>EU_868</code>
|-
| Modem preset || <code>LongFast</code>
|-
| Primary channel || <code>LongFast</code>, default key
|-
| Hop limit || <code>7</code>
|-
| Role || <code>CLIENT</code>, unless the node is sited high and mains powered
|}

== Why 7 hops ==
Scotland is not flat. Towns that are close together are often split by hills, so a message may need a few hops to reach a high router (Tomtain and Cant Hill are the main ones) and a few more to reach the edge of the mesh.

<div class="sm-cx sm-cx-warning">

The official default is 3. More hops means more airtime, and on a flat, busy mesh a high limit adds congestion. We use 7 because of the terrain.

=== How flooding works ===
Meshtastic uses managed flooding. Before a node rebroadcasts a packet, it listens to check whether another node already has. Nodes further away (lower SNR) wait a shorter time, so they tend to relay first and the message moves outward. Routers relay with higher priority.

== Broadcast intervals ==
Keep the mesh quiet, especially for the solar routers:
* '''Node Info''': every 4 hours or more.
* '''Telemetry''': off, or every 4 hours or more. It is off by default on current firmware.
* '''Position''': every 4 hours or more on a fixed node.

See [[Meshtastic/Recommended Settings|Recommended Settings]] for the full list.
