Windows SDK for Windows. This open-source library allows you to integrate the Neo smartpen - Neo smartpen N2 and M1 - into your Windows program.
The Neo smartpen is designed to seamlessly integrate the real and digital worlds by transforming what you write on paper - everything from sketches and designs to business meeting notes - to your iOS, Android and Windows devices. It works in tandem with N notebooks, powered by NeoLAB Convergence’s patented Ncode™ technology and the accompanying application, Neo Notes. Find out more at www.neosmartpen.com
‘Natural Handwriting’ technology based on Ncode™(Microscopic data patterns containing various types of data) is a handwriting stroke recovery technology that digitizes paper coordinates obtained by optical pen devices such as Neo smartpen. The coordinates then can be used to store handwriting stroke information, analyzed to extract meaning based on user preferences and serve as the basis for many other types of services.

SDK handle data and commucation with peer device in other thread. So if you want data get from pen to appear in UI, than you have to execute in UI thread.
// create PenController instance.
// PenController control all pen event method
var controller = new PenController();
// Create GenericBluetoothPenClient instance. and bind PenController.
// GenericBluetoothPenClient is implementation of bluetooth function.
var client = new GenericBluetoothPenClient(controller);You can find bluetooth device using below methods. And get PenInformation object that has bluetooth device information.
List<PenInformation> penList = await client.FindDevices();// bluetooth watcher event
client.onStopSearch += onStopSearch;
client.onUpdatePenController += onUpdatePenController;
