Direct-BT C++ Implementation Details (Part 1)

Sven2 Comments

This is the first article covering Direct-BT‘s implementation details including jaulib.

See Direct-BT, Bluetooth Server and Client Programming in C++ and Java (Part 1) for a little introduction to Direct-BT.

Standard and Proprietary Communication Channels

As described, we were required to utilize the host Bluetooth implementation in the GNU/Linux kernel, i.e. BlueZ/Kernel directly without D-Bus to achieve best performance and access the native HCI, L2CAP/GATT and SMP communication channels directly.

Direct-BT, Bluetooth Server and Client Programming in C++ and Java (Part 1)

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)” →

What is Direct-BT? Where is JogAmp 2.4.0?

What is Direct-BT?

I happily joined Xerxes’s call to enhance the
Bluetooth experience on embedded GNU/Linux for Zafena.

This ended up in a new Bluetooth LE (almost done) and BREDR (in progress)
C++-11 implementation named Direct-BT.

It exposes a modern Java binding to the refactored original TinyB. Continue reading “What is Direct-BT? Where is JogAmp 2.4.0?” →
