Connect Thread Devices to the Cloud with IoT Core
summary
Live demos show MQTT over Thread and CoAP proxy to IoT Core working end-to-end: Nordic nRF52840 dev boards (one on coin cell) connect via a Raspberry Pi + Nordic USB dongle acting as a Thread border router to Google Cloud IoT Core. Firmware uses OpenThread, LwIP, mbedTLS, jwt-c and FreeRTOS for MQTT (telemetry every ~2s); CoAP uses OT CoAP with DTLS and a stateless CoAP→HTTP proxy. Pub/Sub, Cloud Functions and Firestore receive and store the telemetry successfully.
