libble++

Implementation of Bluetooth Low Energy functions in modern C++, without the BlueZ DBUS API.

Includes

• Scanning for bluetooth packets
• Implementation of the GATT profile and ATT protocol
• Lots of comments, complete with references to the specific part of the Bluetooth 4.0 standard.
• Example programs

Design

Clean, modern C++ with callbacks. Feed it with lambdas (or whatever you like) to perform an event happens. Access provided to the raw socket FD, so you can use select(), poll() or blocking IO.

The example programs

• lescan_simple: Simplest possible program for scanning for devices. Only 2 non boilerplate lines.
• lescan: A "proper" scanning program that cleans up properly. It's got the same 2 lines of BLE related code and a bit of pretty standard unix for dealing with non blocking I/O and signals.
• temperature: A program for logging temperature values from a device providing a standard temperature characteristic. Very short to indicate the usave, but not much error checking.

Building the library

There are currently autoconf (./configure) and CMake options. It's not a complex library to build, so either option should work fine.
Autoconf:

./configure  
make

CMake:

mkdir build && cd build
cmake ..
make install

CMake with examples:
Examples will be in build/examples

mkdir build && cd build
cmake -DWITH_EXAMPLES=ON ..
make install
