 An Android library that solves a lot of Android's Bluetooth Low Energy problems.
 
+> **Warning**

+> The new library offers the following improvements over this one:
+>  * 100% Kotlin code
+>  * Scanning for Bluetooth LE devices (scan results as `Flow`)
+>  * Support for Bluetooth LE advertising
+>  * Support for mocking BLE devices (easy testing)
+>  * All BLE operations use `suspend` modifier or `Flow`s
+>
+> Read more on project's Readme file.
