Has anyone successfully connected their Arduino Uno R4 Wifi to Azure IoT Hub and Azure IoT Central? I've been encountering issues related to libraries like based64.h, azureiothub.h, azureiotutility.h, and so on. I'm hoping someone can provide me with an answer or opinion about this problem. Thank you.

What is the issue you are facing?
Did you check Arduino library for Azure IoT and GitHub repo already?
Also, there are few other code examples in IoT Central's Github repository
Do let me know if you have any further queries.

2024-03-03T13:40:21.5833333+00:00 I did check arduino library from github, microsoft website and arduino website as well. But the problem is the library (.h file) is not working. So did you have any arduino codes for azure iot hub connection or latest reference to my question?
