This is a demo with Iotivity 1.0.0 on several different platforms includes
1. An Iotivity demo server on Arduino Due with Grove starter kit
2. An Iotivity demo server on Raspberry Pi 2 with GrovePi python server
3. An Iotivity demo gateway (both client and server) which is able to run on ARM v7 platforms or on just on a PC

The Iotivity demo gateway can find the demo servers on the same local network and send/receive requests, 
and it's also an Iotivity server which is able to be found by other Iotivity client such as Android based Iotivity client
(https://github.com/gerald-yang/android-iotivity-client).

The following are the build instructions and hardware configurations.

Arduino with Grove starter kit (http://www.seeedstudio.com/depot/Grove-Starter-Kit-for-Arduino-p-1855.html)
  Hardware configurations
    1. Arduino Due board

    2. Plug Grove on Arduino Due

    3. Connect Grove sensors to Grove board
         Grove Buzzer:             D2
         Grove Button:             D3
         Grove Serno:              D6
         Grove LED:                D7
         Grove Touch:              D8
         Grove Temperature sensor: A0
         Grove Sound sebsor:       A1
         Grove Light sensor:       A2
         Grove Angle sensor:       A3
         Grove RGB LCD:            SDA1, SCL1
              The second TWI interface on Arduino Due needs to add a 1.5k pullup resister to SDA1 and SCL1 to make it work,
              please see the second_I2C_LCD.jpg.
              For the first TWI, the pullup resister is build-in on the board, no need to add it.

    4. Plug Arduino ethernet shield on Grove

  Build instructions
    1. Build Iotivity on Raspberry Pi 2, please copy iotivity-demo to Raspberry Pi 2 and setup environment
       source ./env-setup

    2. Install packages for building iotivity
       sudo apt-get install scons git-core ssh g++ python-dev autotools-dev libicu-dev build-essential libbz2-dev
                            libboost-thread1.55-dev libboost-all-dev uuid-dev pkg-config libglib2.0-dev libssl-dev
                            zip

    3. Install packages for accessing GrovePi
       sudo apt-get install python-smbus python-setuptools python-pip
       sudo pip install RPi.GPIO

    4. Build demoserver and democlient
       ./build_iotivity_armv7.sh

    5. The demoserver is located in iotivity-1.0.0/out/linux/armeabi-v7a-hard/release/resource/examples/demoserver

    6. Start the python server to read/write sensors and devices
       sudo python2.7 python_server/python_server.py

    6. Start demoserver
       ./run_iotivity_server_rp2.sh
       

On an armv7 board (on Mediatek 7623 with Ubuntu Snappy Core)
    1. Copy the democlient built on Raspberry Pi 2 and Iotivity libraries to Mediatek 7623.
