Low Power Wireless Sensors with AtomVM
summary
AtomVM runs Erlang/Elixir/Gleam bytecode on tiny microcontrollers with few kilobytes of RAM, keeping OTP-style modules like gen_server and JSON parsing functional on constrained devices. Real deployments show LoRa long-range collection nodes forwarding to gateway devices and MQTT over Wi‑Fi for home automation, with discussed tradeoffs: memory vs CPU, missing native routing in LoRa requiring custom protocol work, platform-specific driver limits, and concrete target configurations that did and did not work.
