Meshtastic vs Meshcore

Introduction

LoRa networks use low power long-range radio to send data across devices. When devices relay messages between each other, they form a mesh network. This can help you communicate across open spaces without depending on mobile signal, great for preppers or nerds.

Meshtastic

Meshtastic is an open source mesh network that uses LoRa radios. It supports text messages, location sharing and telemetry. You can join a local channel and chat with others. Many users in my area already use it. Set up involves flashing firmware onto your device, setting radio parameters (use 868 MHz for the UK), and joining a channel. Antenna placement and duty cycle management are important.

Pros

  • Multiple communities across the globe means you have neighbours to chat with and share data.
  • Many devices support the firmware.
  • The user interface is mature and friendly.

Cons

  • Range still depends on how many nodes are around and where they are placed.
  • It may have more network traffic than a bare bones mesh.

MeshCore

MeshCore is a newer project that also uses LoRa. It tries to improve packet routing and network efficiency. You could set up a network if you want to experiment.

Pros

  • Better routing algorithms may give more reliable connections when you have many nodes.
  • Gives you more control over the network.

Cons

  • No one in my area seems to use it yet, so I felt like I was building a network from scratch.
  • Firmware and community support are still developing.
  • Relies on repeaters rather than true p2p meshing.

My devices

Heltec v3

This board is good for a base node. Mount it on a high point like your roof to give the best coverage. Make sure you use the correct frequency and antenna.

LILYGO T‑Deck Plus and Pro

These boards have large screens and batteries, which makes them ideal as portable nodes. Carry them on walks or bike rides to test coverage.

LILYGO T‑LoRa V2.1‑1.6

This board is simpler but cheaper. You can use it as a fixed node in your garden or local community centre to add more relays in the mesh. It's primary use was originally to be a Paxcounter.

Why Meshtastic is the better choice for now

Since most locals already use Meshtastic, I get more value from it. You can send messages and share data right away. MeshCore may become useful when more people join and the routing improvements pay off.

Tips for usage

  • Put nodes on rooftops, hills and open fields to get the best range.
  • Align your antennas and avoid obstacles.
  • Follow UK regulations on transmit power and duty cycle.
  • Encourage friends to add more nodes to grow the network.
