I was skeptical, but now stand corrected: you can connect an IoT Starter Kit designed for kids and beginners to Azure IoT Hub with no code, and it definitively is not that hard. See how that's done with the M5Go IoT Starter Kit from M5Stack, based on an ESP32 chip and using Blocky. ERRATUM: In the video I am mentioning that you need to upload a root cert on the device to allow it to authenticate the IoT Hub server. This is incorrect. The step to upload a cert file is not necessary as the MQTT client bypasses the server authentication step under the hood. Just set SSL to True and you can skip directly from 17:52 to 19:18.
