Trevor Attema decided to repurpose his Nokia E63 Blackberry-life phone with a custom STM32H7 board with a LoRa radio while keeping the enclosure, display, backlighting, keyboard, and speaker which he calls the Off The Grid Messenger, or OTG Messenger for shorts. Nokia E63 LoRa messengerNokia E63 LoRa messenger The custom board also adds Microchip ATECC608 crypto authentication chip for encrypted messages, and the LoRa Messenger would allow a theoretical transmission range of 16 kilometers in line of sight which would allow a small group of people to stay connected in an area where cellular networks are not available either due to being in a remote area or a disaster zone. This allows also secure communication, so the telcos and authorities would not be able to (easily) access your communication history. The software has been written in C/C++ and released on Github. Libraries and tools used for development include STMicro Touch GFX GUI adapted to function with a Nokia e63 keypad, STM32 ChromeART for graphics, STM32CubeIDE, and STM32CubeMX hardware configuration platform. The OTG Messager relies on "self-healing mesh networking" for communication, where each device acts as a relay station. Future updates to the software should include support for group chat, voice messages, and an address book.
