How to Join MapleMesh

A Beginner’s Guide to Connecting to the Local MeshCore Network

What is MapleMesh?

MapleMesh is a community communication network built using LoRa (long range, low power radios, called “nodes”) and MeshCore, an open-source project that lets small radios send text messages and GPS information without cell towers or Wi-Fi. Individual nodes work together to create a mesh network. The more units in use, the stronger the network!

The “mesh” part means each device passes along messages for others, so even if you’re far away from someone, your message can hop across multiple devices until it reaches them.

What is LoRa?

LoRa is the wireless technology this network uses. It’s designed to send small amounts of data—like text messages while using very little power.

Think of it as walkie-talkies for data. Instead of voice, LoRa carries text and (sometimes) location information.

Prerequisites

Before you can connect to MapleMesh, you’ll need:

A MeshCore-capable radio device

This is a small, consumer-purchasable device that contains a LoRa radio chip and can run the MeshCore software.
Several ready-to-use or kit-based options are listed later in this guide.

A smartphone or computer

You’ll use this to set up your device and send/receive messages through the free MeshCore app or web tools.
- Google Play Store (for Android devices) link
- iPhone app (for iPhones) link

Basic setup information

Region: US (to match US frequency rules)
Channel settings: set the modem preset to medium_fast (this balances speed and range and is what MapleMesh uses)

Power source

Most devices include a rechargeable battery or can run from USB power.

Step-by-Step Setup

Get a MeshCore Device Pick one of the hardware options below (see “Hardware Choices”). Make sure you choose the 915 MHz / US version.
Install or Confirm MeshCore Software
- Many devices come with MeshCore already installed.
- If yours doesn’t, you’ll need to flash your device.
Connect Your Device
- Use the MeshCore mobile app (Android or iOS) or connect by USB to your computer, depending on whether you flashed a USB or Bluetooth companion.
- The app will recognize your device and let you configure settings.
Set the Region and Modem Preset to Join the MapleMesh Network
Test Your Connection
- From the app, try sending a text message.
- If you’re in range of another MapleMesh device, your message will hop into the network.
- Walk around or place your device outside to improve range

Quick Tips

Height matters! Getting an antenna even a few feet higher can sometimes make a huge difference in range.
Line of sight matters: devices work best when not blocked by buildings or hills. If you’re inside a building, don’t be surprised if your range is cut in half or worse.
Antennas make a difference: The right antenna for the right situation makes a big difference in range.
More nodes = stronger mesh: even if you’re not chatting, just running your node helps the network grow.
