A quick demonstration on sending data from Azure to a Wi-Fi connected IoT device. This uses the Azure IoT Hub Cloud-to-Device feature.

The M5Flow (blocky) graphical program builder makes it easy to drag and drop a program that receives C2D messages from Azure IoT Hub.

I've been playing with the M5Stack Core2 devices and wanted to see how hard it would be to create a program that sends data Azure to an IoT device without having to actually write any code. They support several development environments including a graphical Python builder. The UIFlow IDE includes common cloud integration blocks for Azure and AWS.

The IDE shown in this video is UI Flow Desktop V1.7.5. The connection string for later versions, like the web 1.8.7 is different.
