Tiny Bluetooth LE Library
This project aims to create clean, modern and easy to use Bluetooth LE API. TinyB exposes the BLE GATT API for C++, Java and other languages, using BlueZ over DBus.
Up to date API documentation can be found:
- for C++: http://iotdk.intel.com/docs/master/tinyb/
- for Java: http://iotdk.intel.com/docs/master/tinyb/java/
A guide for getting started with TinyB on Java is available here: https://software.intel.com/en-us/java-for-bluetooth-le-apps.
TinyB requires CMake 3.1+ for building and requires GLib/GIO 2.40+. 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
Building debug build:
Using clang instead of gcc:
Cross-compiling on a different system:
-DCMAKE_CXX_FLAGS:STRING=-m32 -march=i586 -DCMAKE_C_FLAGS:STRING=-m32 -march=i586
To build Java bindings:
To build documentation run:
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.
- 0.5.0 ** Added notifications API ** Capitalized RSSI and UUID properly in Java ** Added JNI Helper classes for managing lifetime of JNIEnv and Global Refences
- 0.4.0 - Added asynchronous methods for discovering BluetoothObjects
