Sending commands from Azure IoT Hub (via mqtt) to Arduino (nodemcu)
A minimal Arduino sketch for receiving MQTT commands from Azure IoT Hub on a NodeMCU (ESP8266). This is a 2018 personal learning project, not a library or reusable tool — it exists to demonstrate the concept once.
The .ino and .c files together show the full connection flow, so someone wiring up IoT Hub to an ESP8266 for the first time can see a working skeleton without sifting through a larger SDK. Separating config into iot_configs.h is at least structurally tidy.
Zero stars, zero forks, last touched in 2018 — the Azure IoT Hub C SDK has changed considerably since then and this will likely not compile against current libraries without fixes. No SAS token generation is documented, which is the part that actually trips people up. The README is in Portuguese with no English translation and links to an Instagram video as its primary documentation. No error handling, no retry logic, no TLS certificate pinning — fine for a demo, fatal for anything real.
