By Utilizing the Android JNI and the capabilities for Android plugins on Unity to interact with the MonoBehaviour ecosystem, the .NET side inside Unity can communicate with the plugin, while the plugin can communicate back using the MonoBehaviour SendMessage method. The plugin contains a Singleton pattern that gets called from the BleManager script as an AndroidJavaObject. With this object you can call static methods and pass parameters, which takes care of communication from Unity to Android's BLE system. The plugin will then operate and send changes to Unity using the MonoBehaviour SendMessage method to pass JSON information to the BleAdapter.
Most of the BLE operations utilize the .NET event system, so information can be passed through all of the classes that need it. The BLE operations rely on the abstract BleCommand class. This class can be queued up into the BleManager, which executes the queued up commands one by one, or removes them from the queue if they're extending their TimeOut time.
If you're interested, I've written an article about the inner workings of the library over on my website. You can check it out over here: Creating an Android Bluetooth Low Energy plugin for Unity.
