How it Works
The app "talks" with "IoT Semplice" by using Bluetooth Low Energy. You can set a time (seconds) and you can choose the blue or red led. You can easily try the app by downloading the apk.
The main purpose is to show (using led) how to deal with "IoT Semplice" ports.
The idea of this app was developed during Droidcon Italy 2016 Hackathon.
