Functional IoT with Elixir and Nerves
summary
Nerves boots Elixir’s BEAM as firmware and ships an OTP release burned to an SD image (rootfs A/B) so devices use blue‑green A/B rootfs updates and avoid bricks; firmware images run ~30 MB and are signed and delivered over Nerves Hub with fleet groups and OTA. Hardware support includes every Raspberry Pi, BeagleBone and custom boards; a <$10 nerves_key HSM keeps private keys on‑chip. Production users include Rose Point (high‑throughput CAN on boats, ~80% Mississippi traffic) and demos show Phoenix LiveView pushing ~2 million device connections.
