LoRa (Meshtastic & MeshCore)

GhostESP turns an SX1262 radio into a mesh node. Only one of two protocols runs at a time:

Interop is the point: GhostESP uses the same sync word, channels and wire encryption as Meshtastic firmware, so it joins an existing mesh without anything being reflashed.

Where to Go Next

• First run: set a region, start the radio, send your first message
• MeshCore mode: use MeshCore instead of Meshtastic
• Command reference: every lora, mesh and meshcore command
• Phone app: pair the official Meshtastic app
• Hardware: supported boards and wiring

How You’ll Use It

On the Device

Open LoRa from the main menu. It opens on a status screen without starting the radio; the first row starts the selected protocol when the radio is off.

• Conversations are grouped per channel and per contact, so channels stay separate.
• Outgoing messages show Sending, Delivered, Sent or Failed. Tap a failed one to reopen it in the composer and retry.
• Encoder boards: double-press on the status screen toggles the radio.
• Heltec OLED: press PRG to cycle pages. On the LoRa page a double-press toggles the radio, and with the radio off the page shows PRESS 2X TO START.

Keep It Running

Auto-start is opt in. The protocol is remembered, so you set it once:

lora autostart meshtastic     # or: lora autostart meshcore

The radio starts a few seconds after the interface, once boot has finished. Meshtastic needs a saved region before it can transmit; MeshCore does not.
