Samsung launched its S Pen software developer kit for the Galaxy Note 9 in a bid to get third party software providers to buy into the stylus and enterprise possibilities.
The company tipped its plans for the S Pen SDK when it launched the Note9. As a refresher the S Pen for the Galaxy Note 9 uses Bluetooth Low-Energy so the stylus can be used as a remote control for presentations and operating the camera.
For Samsung's Galaxy Note 9, the S Pen game plan revolves around making the stylus a more natural and meaningful to interact with apps and the smartphone. Samsung's S Pen also has an opportunity given that Apple didn't add Apple Pencil support to its latest line of iPhones--XS, XS Max and XR.

The SDK documentation highlights how the S Pen's remote control functions can work and be implemented. Samsung noted that the SDK can add S Pen functionality to "as many app features as you want."
According to Samsung, the framework is that S Pen's BLE transmits to the S Pen Framework that'll produce an event for an application. BLE events are not sent directly to the app, but are converted to events by the S Pen Framework.
Here's a look at how the framework works and all the documentation for developers.
