This is the first article covering Direct-BT using version 2.7.1 and may give you a little introduction into this project.
See Direct-BT C++ Implementation Details (Part 1) for some insight view.
Overview
Direct-BT provides direct Bluetooth LE and BREDR programming, offering robust high-performance support for embedded & desktop with zero overhead via C++ and Java.
It supports a fully event driven workflow from adapter management, device discovery to GATT programming, using its platform agnostic HCI, L2CAP, SMP and GATT protocol implementation.
Multiple Bluetooth adapter are handled, as well as multiple concurrent connections per adapter.
Peripheral server device programming is supported as well as the central client, which is also used for Java and C++ self unit testing across two or more Bluetooth adapter. Continue reading “Direct-BT, Bluetooth Server and Client Programming in C++ and Java (Part 1)”
