Reliable off-grid communication sits at the core of our drone business. At Bendigo Aerial, we operate in rural and remote areas. Mobile coverage drops out fast. Communication gaps create risk for crews, pilots, and people on the ground. This is where Meshcore works for us.

We have used Meshtastic for secure messaging, repeater links, and off-grid coordination. It worked well in many cases. The limitation came down to coverage. In areas without repeaters, messages often stopped around the 15 km mark. No repeaters meant no path forward. Meshtastic relies on client devices rebroadcasting messages. This increases airtime traffic and packet collisions when repeater density is low. In sparse networks, delivery reliability drops fast.

Meshcore solves this problem for our use case. The repeater network is stronger, and the coverage is wider. Messages travel further because more repeaters are active and reachable.

What Is Meshcore

Meshcore is an off-grid communication platform built on LoRa radios. It focuses on mesh routing and repeater-first design. Devices form a network without internet or mobile service. Messages move from node to node through fixed repeaters.

Meshcore separates device roles. Companion nodes send messages. Repeater nodes forward packets only. This keeps traffic predictable and reduces congestion. Distance depends on terrain, antenna placement, and repeater density. For a local drone business, this matters. More repeaters mean more reliability. Meshcore supports AES-encrypted direct messages and encrypted private channels by default. Keys stay local. No cloud dependency exists.

Meshcore Coverage and Repeaters

Coverage defines usefulness. Meshcore benefits from an active repeater network across large parts of remote Australia. Repeaters act as fixed relay points. They stay online. They pass messages across long distances.

Meshcore supports up to 64 hops per message. Meshtastic defaults to 3 hops and allows a maximum of 7. This single design difference explains the range gap. From Bendigo, messages reach regional Victoria and beyond Melbourne. They reach interstate paths when repeater chains exist. With Meshtastic, the gaps between repeaters limited range. In some areas, messages stalled at 10 km. That created uncertainty and undeliverable messages.

How to Set Up a Repeater

  1. You flash the firmware to the device as a repeater
  2. You select the region preset- Australia (Narrow)
  3. Give the repeater a name
  4. Optional GPS location for mapping
  5. Set a GUEST password and ADMIN password
  6. Deploy the repeater high with a line of sight

Repeaters forward packets only. They do not generate traffic. This keeps RF airtime clean and improves delivery under load.

How to Set Up a Companion Node

Companion setup mirrors repeater setup. We use the T114 and Lilygo T-Echo devices, the same hardware used previously with Meshtastic.

  1. Flash Companion Bluetooth firmware
  2. Pair with the Meshcore mobile app
  3. Enter Bluetooth PIN
  4. Select Australia (Narrow) from the preset
  5. Check companion settings on your phone
  6. Reboot and send an Advert
  7. Nearby repeaters, rooms and users appear

Companion nodes do not rebroadcast traffic. This prevents accidental network flooding from devices carried in pockets or vehicles.

Private Channels in Meshcore

Private channels in Meshcore support encrypted team communication for operational use. Each channel uses a shared secret key, keeping messages off public networks and hidden from maps and discovery tools. Devices sync keys quickly, either with a QR Code or a private key and join without extra configuration, which keeps setup time low in the field. All flight coordination, crew messaging, and site updates stay contained within these private channels.

Public Rooms and Network Traffic

Meshcore supports public rooms. Traffic volume is high in populated areas. Rooms store messages. Users do not need to stay online to receive them. Messages remain available when a device reconnects. Public rooms serve an important role outside of commercial operations. They support community communication in small towns, regional centres, and local interest groups. In disaster scenarios, rooms provide a shared space for coordination during rescue, recovery, and management efforts. For drone operations, public rooms offer visibility and situational awareness, but private channels remain the primary tool for operational messaging.

Using Meshcore in Drone Operations

Running a drone business and drone operations rely on coordination. Pilots need updates in real time. Ground crews need clear instructions. Observers need alerts. In some operations, telemetry from sensors and other data points also needs to move reliably between teams.

Meshcore supports this communication without mobile, internet, or satellite services. Messages travel through repeater chains, and coverage remains consistent across large areas. This system continues to function during telecommunication network outages, in fire zones, and beyond infrastructure corridors. For drone work in rural and remote locations, this reliability removes uncertainty and improves on-site coordination.

Comparison With Meshtastic and Downsides of Meshcore

Meshtastic is a mature platform. It offers broader tooling, more telemetry features, and a well-established ecosystem. It suits users who value application features and device integrations.

Meshcore focuses on routing efficiency and repeater density. It uses a flood-to-path routing model where the network discovers a path once and then reuses it. This approach reduces airtime use and improves message delivery across larger networks with multiple repeaters. In areas with structured repeater coverage, this design performs better for long-distance messaging.

Meshcore has downsides. The project launched publicly in 2025 and continues active development. The Android app still shows bugs at times. Feature depth remains lower, and telemetry tools are limited. Stability improves with updates, and repeater coverage continues to expand, but Meshcore prioritises delivery reliability over application features.

Why Meshcore Works for Bendigo Aerial

Drone operations depend on message delivery. Coverage matters more than interface polish.

Meshcore works because repeaters exist where our drone work happens. Messages travel further, and routes remain stable across regional and remote areas. The network design suits planned repeater deployment. Traffic stays controlled. Airtime stays clear. Delivery stays consistent.

For Bendigo Aerial, this means crews stay connected across farms, forests and infrastructure corridors. Messages move beyond 100 km without relying on mobile coverage. The switch was not about novelty. It was about reliability under pressure. Meshcore delivers reach, structure and control. That is what off-grid drone operations require.
