Connecting Microcontrollers to the Cloud Using MQTT, BLE, and HTTP
summary
Covers concrete tooling and outcomes: open source FreeRTOS kernel plus Android/iOS SDKs, reference ports for ESP32 and dozens of dev kits, and demo code for MQTT over BLE and Wi‑Fi provisioning over BLE. Describes security and scale specifics — TLS 1.2 and X.509 auth, code‑signed firmware, two‑partition OTA images streamed over MQTT, and reboot/rollback behavior. Useful if evaluation needs, porting steps, or an OTA implementation are the deciding factors.
