From 116790d6e1e808b77dfc8f18b8bdae8566a4bf6e Mon Sep 17 00:00:00 2001 From: blub <63512588+blubdidup@users.noreply.github.com> Date: Sun, 5 Jan 2025 13:02:09 +0100 Subject: [PATCH] Update lora.mdx Made clear that one can only communicate with devices that have the same "modem preset" enabled. Although it makes perfect sense, it took me some time to figure that out. --- docs/configuration/radio/lora.mdx | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/docs/configuration/radio/lora.mdx b/docs/configuration/radio/lora.mdx index ec0c491b..b3a6caff 100644 --- a/docs/configuration/radio/lora.mdx +++ b/docs/configuration/radio/lora.mdx @@ -29,7 +29,9 @@ Sets the region for your node.

Presets are pre-defined modem settings (Bandwidth, Spread Factor and Coding Rate) which influence both message speed and range. The default will provide a strong mixture of speed and range, for most users. + +It is important to understand that a device/node will ONLY be able to communicate with a device(s)/node(s) which has/have the same preset (hence the same lora radio parameters like Bandwidth, Spread Factor and Coding Rate) configured. So if you change to a "non-standard" `Modem Preset` i.e. `LONG_MODERATE` your would only "see" and be able to communicate with devices/nodes which are also set to this default meshtastic `Modem Preset`. In conclusion: it be beneficial to keep the `LONG_FAST` (Default), to have a better chance to communicate with other devices/nodes. The presets are designed to provide further options for optimizing either speed (and reduced network congestion) or range, which can be useful for two real world scenarios:
