  Tiny Bluetooth Library
  Using TinyB
  

Tiny Bluetooth Library
This project aims to create Bluetooth GATT bindings for C++, Java and
other languages, using BlueZ over DBus. Most of the code is
automatically generated using gdbus-codegen, including a few additions
to the default behaviour, such that it also generates the C++ classes,
which wrap the functions normally generated by gdbus-codegen.
Using TinyB
TinyB requires CMake 3.1+ for building and requires GLib/GIO 2+. It
also requires BlueZ with GATT profile activated, which is currently
experimental (as of BlueZ 5.37), so you might have to run bluetoothd
with the -E flag. For example, on a system with systemd (Fedora, poky,
etc.) edit the bluetooth.service file (usually found in
/usr/lib/systemd/system/ or /lib/systemd/system) and append -E to
ExecStart line, restart the daemon with systemctl restart bluetooth.
mkdir build
cd build
cmake ..
make
make install
The last command will create the include/ and lib/ directories with a
copy of the headers and library objects respectively in your build
location. Note that doing an out-of-source build may cause issues when
rebuilding later on.
Our cmake configure has a number of options, cmake-gui or
ccmake can show you all the options. The interesting ones are
detailed below:
Changing install path from /usr/local to /usr
-DCMAKE_INSTALL_PREFIX:PATH=/usr
Building debug build:
-DCMAKE_BUILD_TYPE=DEBUG
Using clang instead of gcc:
-DCMAKE_C_COMPILER=/usr/bin/clang -DCMAKE_CXX_COMPILER=/usr/bin/clang++
Cross-compiling on a different system:
-DCMAKE_CXX_FLAGS:STRING=-m32 -march=i586
-DCMAKE_C_FLAGS:STRING=-m32 -march=i586
To build Java bindings:
-DBUILDJAVA=ON
To build documentation run:
make doc
The hellotinyb example uses a TI
Sensor Tag from which it reads the ambient temperature. You have to
pass the MAC address of the Sensor Tag as a first parameter to the
program.
