ARM mbed
summary
Claims that ARM is shipping a microcontroller-focused stack for LoRaWAN with tiny RAM footprints and added silicon security, cites 99% of all smartphones use ARM SoCs and a typical IoT device lifespan of about 10 years. Demonstrates a custom Firefly 1705 board with external flash and a Semtech SX1272 module enabling over‑the‑air firmware updates, mentions mbed/embassy TLS primitives, gives real deployments: container seals that reveal diesel theft and cow sensors that predict heat and illness, and says OTA updates and hardware roots of trust are working parts.
