Embed your downloaded certificates directly into your code or store them in the ESP32's LittleFS/SPIFFS filesystem . 3. Firmware Development The ESP32 firmware should perform three main tasks:
Once data reaches AWS IoT Core, you can route it to other services using : Building Complete IoT Solution with ESP32 and A...
Publish sensor data to a specific topic (e.g., esp32/sensor/data ) and subscribe to a command topic to receive instructions from the cloud. 4. Backend Processing & Visualization Embed your downloaded certificates directly into your code
