iot-core-micropython

This project provides a working example of using MicroPython to connect ESP32-based devices to Google Cloud IoT Core. It demonstrates how to securely transmit sensor data (like temperature readings) from resource-constrained microcontrollers to Google Cloud's managed IoT service. The implementation handles key steps such as device authentication via RSA keys and message publishing to Cloud Pub/Sub. ## Key Features - **ESP32 Integration** — Provides specific instructions and code for flashing and running on Espressif ESP32 hardware. - **Cloud IoT Core Connectivity** — Implements the MQTT bridge protocol required to register a device and publish telemetry to Google Cloud IoT Core. - **RSA Authentication** — Includes utilities to generate and format RSA key pairs for secure device authentication with the cloud service. - **Telemetry Publishing** — Example code that publishes structured JSON messages (e.g., temperature and device ID) from the device to the cloud. - **Configurable Setup** — Uses a `config.py` file to manage device credentials, cloud project details, and network settings. ## Philosophy The project focuses on providing a clear, practical reference for developers wanting to connect MicroPython-powered hardware to a major cloud IoT platform, emphasizing security and simplicity.
