Sending Messages Public Channel Messages Messages sent to the "Public" channel are received by all nodes on the network that share your channel key. For the standard community network using the USA/Canada preset, all nodes on the public channel will see your ...

Radio Settings Access via Settings → Radio (or Device → Radio Config depending on app version). Preset Selection The most important radio setting. Always use the preset that matches your local network: USA/Canada (Recommended) — North American standard: 91...

Short Answer Meshtastic messages are encrypted, but the level of protection depends on which channel you're using. The default channel (LongFast) uses a known public key and provides essentially no privacy. Custom channels with randomly generated keys provide ...

How Position Data Spreads When position reporting is enabled on a Meshtastic node, GPS coordinates are broadcast as position packets on the mesh. These packets travel through the network like any other message and are visible to all nodes that receive them. W...

MeshCore Encryption Summary MeshCore provides two layers of encryption: Channel encryption — AES-256-CTR with a key derived from the channel configuration. All nodes on the channel share this key. Direct message encryption — ECDH key exchange (Curve25519 ...

Meshtastic and MeshCore operate in the 902-928 MHz ISM band under FCC Part 15 in the United States. This section explains what the rules require, what they allow, and what you need to know for compliant operation. FCC Part 15 Basics Part 15 covers unlicensed ...

In Canada, LoRa mesh networking in the 902-928 MHz band operates under Innovation, Science and Economic Development Canada (ISED) regulations, primarily RSS-210 and RSS-GEN. Key Canadian Rules License-exempt operation — The 902-928 MHz band is license-exem...

LoRa mesh hardware designed for North America operates on 902-928 MHz, which is an ISM band in the US and Canada but is not an ISM band in most of the rest of the world. Traveling or deploying internationally requires care. European Union: 868 MHz Europe uses...

Quick reference definitions for terminology used throughout this wiki. Terms are organized alphabetically. A ACK (Acknowledgment) A confirmation packet sent by the receiving node to confirm a message was received. Meshtastic uses ACKs for unicast (direct) me...

Ham Radio Operators and Mesh Networking Amateur radio operators — "hams" — have been among the earliest and most enthusiastic adopters of LoRa mesh networking. The overlap is no accident. Decades of experience with emergency communications, antenna theory, ra...

Callsign and Identification in Mesh Networks One of the most common questions from licensed amateur radio operators entering the LoRa mesh world is: do I need to identify my mesh node with my callsign? The short answer is no — but the longer answer involves u...

APRS and Meshtastic Integration APRS (Automatic Packet Reporting System) and Meshtastic are complementary systems that serve overlapping but distinct communities and use cases. Bridging them extends the reach of both networks and gives mesh operators access t...

Device Configuration Settings The Device configuration section (Config > Device) controls fundamental node behavior: its role in the network, how it handles rebroadcasting, node info broadcasts, and administrative access. These are the most impactful settings...

Position Configuration Settings The Position configuration section (Config > Position) controls how your node acquires, reports, and manages GPS and location data. Getting position configuration right affects mesh map accuracy, battery life, and channel airti...

Network Configuration Settings The Network configuration section (Config > Network) controls how ESP32-based Meshtastic nodes connect to IP networks — WiFi and Ethernet — and associated services like NTP and remote logging. These settings are only relevant fo...
