Changelog

This version of the firmware includes an AI model that has been trained to recognize ambient air, whiskey, and coffee.
- When a smell is successfully identified, the right most screen will not only give you a confidence level (in %), but also display a happy face emoji (🙂) indicating that the smell is a familiar one, i.e. the prediction is to be trusted for similar sensor data was encountered during the training of the model ;
- A thinking face emoji (🤔) is an indication that the prediction made by the neural network is to be taken with a grain of salt, as the smell does not look very much like any of the smells "seen" during the training phase.
Added support for connecting to Azure IoT Central. When enabled, this allows the artificial nose to send its findings in real-time (using Wi-Fi) to the Azure IoT cloud platform.
- Follow the instructions to setup an Azure IoT Central application, as well as to configure the Wi-Fi + Azure IoT Central credentials of your Wio Terminal device
