LilyGO T-Lora Pager

By the end of this page you have a T-Lora Pager that sends messages by radio, without internet: with Ratspeak Handheld as a standalone Reticulum node, or with Meshtastic.

Tier 0: no internet · Works without internet.

Draft: this page has not been checked on a real device yet, and its Farsi has not been reviewed. Use with care.

Before anything else, read Before you switch on a radio. This device is physical evidence, and radio transmissions can be located.

The T-Lora Pager is the same family as the T-Deck Plus, in the shape of a pager: smaller and lighter, with a landscape screen, a keyboard and a small wheel for navigation instead of a trackball. It takes the same two firmwares.

1. Buy

  1. A LilyGO T-Lora Pager, with LoRa radio, keyboard and screen.
  2. Frequency: the 868 or 433 MHz version, whichever the others in your group have. Every device in a group must use the same frequency and radio preset. Know your local law.
  3. The antenna in the box works; a better one with an SMA connector extends the range.

Never switch the device on without an antenna.

2. Install the firmware

Two choices, each its own world:

  • Ratspeak Handheld: the Reticulum messenger, with the Offline Inbox and the same addresses as this site. On a computer with Chrome or Edge, open Ratspeak's download page (ratspeak.org/download.html); if the T-Lora Pager is in the device list, choose it and press "Flash in browser". If it is not listed, it is not supported yet; use Meshtastic.
  • Meshtastic: the neighbourhood mesh, guide: Meshtastic. The Meshtastic web flasher knows the device as T-Lora Pager.

Connect the device by USB. If it is not found: switch it off, hold the BOOT button, switch it on, then connect USB.

3. First start (Ratspeak)

  1. Choose Standalone mode.
  2. The device creates a Reticulum identity and asks for a display name. Do not use your real name.
  3. The default radio preset is Medium Fast. If your group uses another preset, use that one.
  4. Scroll with the wheel and press it to select.

4. First message

  1. On the home screen, announce yourself.
  2. In Peers, choose someone and open a chat.
  3. Type and send. A message is yellow while in transit and turns green once delivered.

5. When there is internet

In Settings, Propagation, AUTO mode connects the device to nodes over Wi-Fi so messages can leave the mesh and wait in our Offline Inbox. The addresses are on Ways to connect.
