Android Bluetooth Low Energy Guide (Connect to a BLE sensor) - Android Studio Tutorial with Kotlin

In this tutorial I will show you how you can connect to a BLE sensor/device from your Android Applikation using Android Studio and Kotlin. We will build a simple UI which refreshes every second to update the values retrieved from a BLE sensor. You will also see how to properly handle all necessary permissions and check for the Bluetooth state during runtime.
