DeviceHub C Library

Description

DeviceHub C library wraps the DeviceHub MQTT APIs in a easy to use library to be used on resource constrained hardware or C applications

Requirements

The wrapper depends on paho-mqtt library (an open-source client implementation of MQTT and MQTT-SN messaging protocols)

Install

For installing the Paho MQTT library for C use this link :

 http://www.eclipse.org/paho/clients/c/

The C client is built for Linux with cmake and gcc.

To build:

 mkdir build
cd build
cmake ..
make

To install:

 sudo make install

RaspberryPi setup

 mkdir devel
sudo apt-get install libssl-dev
git clone http://git.eclipse.org/gitroot/paho/org.eclipse.paho.mqtt.c.git
cd org.eclipse.paho.mqtt.c.git
make
sudo make install
sudo apt-get install cmake
git clone https://github.com/devicehubnet/devicehub_c.git
cd devicehub_c.git
mkdir build
cd build
cmake..
make
sudo make install

Test description

To test :

	./devicehub_test # after make , in the build directory

The test consists of some values published into a "humidity" sensor and "temperature" sensor, also a subscribe on an actuator "light". The result can be seen , if you have created the sensors and the actuator with the names mentioned on your account at devicehub before you run this test.
