OFF Grid Messaging projects

Off-grid messaging covers text and telemetry over LoRa when mobile service or Wi-Fi is unavailable. On the T-Deck, Meshtastic provides a broad mesh ecosystem and established device workflow, while MeshCore offers a different companion-radio and mesh stack. Both make use of the handheld’s keyboard and display, but firmware, companion software, network behavior, and interoperability should not be assumed to match. Prove the T-Deck hardware with vendor examples, then choose one ecosystem and the exact radio-equipped board variant. The SX1262 frequency band, antenna, regional plan, and transmit limits must all agree; never transmit without a suitable antenna or use a configuration prohibited in your country. Compare compatible devices, explore original projects and use the linked guides to get moving.
