EMoL: Erlang Messaging and Monitoring over LoRa
summary
Library implements Erlang-like messaging and monitoring over LoRa using AtomVM + LoRa driver, exposing erlang:send/2 and monitor_node/2 style APIs so the leader-election code need not change. It queues transmissions with parallel servers to avoid interrupted frames and enforces regulatory idle times, adds ~45 bytes overhead to payloads, and offers monitoring by receiving periodic messages with monotonic timestamp checks to detect restarts or timeouts. No built-in encryption; tested on ESP32/STM32 hardware and with antenna shielding to validate partition tolerance.
