This project provides tools for working with bluetooth proximity beacons on Windows 10. The code is ported from the Android Beacon Library, and while far less complete it does work for basic beacon transmission and detection use cases.
There is currently no binary distribution so you have to compile this yourself and link it in with your project, or copy the code manually.
Much work remains to be done to make this as complete at the Android Beacon Library. If you'd like to help, please open an issue on the project or dive right in with a pull request.
