The first alpha release of Blaubot 2 is now available from jCenter and MavenCentral. It contains plenty of new features like Bluetooth support for Windows, Mac OS, and Linux based on BlueCove and a WebSocket adapter based on Netty. You can now define a central server instance using the usual connectors and acceptors to which all of the Blaubot instances of a network try to establish a connection. If one instance succeeds, you are able to reach your server from all instances (relay). Note that the factory API will change with the next alpha release. Check the quickstart page for example code and download links.
