Meshtastic @ Disobey 2026

Design principles, i.e. "why these settings?":

Short range, at the event or at the immediate surroundings.
As little extra traffic (e.g. telemetry) as possible to save airtime.
No position broadcast, because we're inside a building any way.
No MQTT, because this is a) kind of a test and b) an event thing, not an internet thing

Settings

Region: EU_868
LoRa preset: SHORT_FAST

All things MQTT: No
Disable telemetry (or at least use a large interval, e.g. 3h)
Use a reasonable nodeinfo broadcast interval (e.g. 3h)
Disable (at least smart) position broadcast
