This document discusses Samsung's work with open source projects like Tizen and IoTivity to develop Internet of Things (IoT) technologies. It describes how IoTivity provides a framework for seamless device connectivity and interoperability using open standards and security. The document outlines examples of building an IoT server on a Raspberry Pi device running Tizen to share GPS data, and creating IoT clients on Tizen phones and wearables to display the location data. The goal is to demonstrate how developers can build their own open source IoT solutions that interact with commercial products using these frameworks and open source building blocks.

IoT ? You said ?
● “I” like Interoperability
– Do we want all devices exposed to the Internet ?
– <blink>Local connectivity between devices</blink>
– Today, gateway is a reasonable answer
● “O” like Openness
– Open standards, protocol, implementations
● “T” like Trustworthy
– Security is Sine qua non condition for IoT

4. Samsung Open Source Group 4
“T” like platform
● Integrates many existing components :
– Mainline Linux kernel with SMACK security module
– libc, X11/Wayland, GStreamer, EFL, WebKit/Blink
● Split into profiles for specific features
– Mobile, Wearable, IVI...
● Shipped into consumer electronic products
– 2011 … 2012 ... 2013 … 2014 … 2015 … 2016 ...

5. Samsung Open Source Group 5
“I” like framework
● Seamless device to device connectivity for IoT
– Core: Discovery, Secure Transmission, Data/Device
– Plus profile services : SmartHome, Automotive, Health...
● C/C++ library (Apache 2.0)
– RESTfull design : CoAP and CBOR
● Backed by Open Connectivity Foundation
– Establishes standard, certification
– With Industry support (Samsung, Intel, Cisco, GE, +170)

6. Samsung Open Source Group 6
“O” like Openness
● Tizen and IoTivity are
– FLOSS LinuxFoundation collaborative projects
● IoTivity / OCF
– Not tied to Tizen or Linux or any vendor
● Cross platform : Linux, Yocto, Tizen, Android, MCUs, TBC
– Abstract Transport :
● IP, Bluetooth, BLE, WiFi, +plugins (Zigbee, LTE, NFC)
– Backed by Open Connectivity Foundation
● Open standard, with 170+ members

7. Samsung Open Source Group 7
Today's reality
● Tizen:3.0 platform supports IoTivity
– Only on development devices (Single Board Computers)
● Some 2.x products are supporting Native APIs
– On actual devices : Mobile and Wearables !
● IoTivity is also supported outside Tizen
– Automotive: Poky based system (GENIVI, AGL, ...)
– Bridges, Web, Cloud : IoTivity node
● Open many developers opportunities !
– Convergence

Let's practice

9. Samsung Open Source Group 9
Challenge : IoT GPS Map
● Share a GPS position to nearby devices
– https://youtu.be/Y7gwAlaoq5U#iotivity-gears2-20160427rzr
● Using IoTivity on Tizen powered devices
– Make a basic server:
● shares a resource (pair of float numbers)
● To run on supported device
– Make a basic client:
● displays position on a map
● To run on consumer product(s)

10. Samsung Open Source Group 10
Single Board Computer on Tizen 3
● RPI 0
– 5 EUR
– Yocto
– GPIO
– GPU
– USB
– ARMv6
– No Eth
● RPI 2
– ARMv7
– Ethernet

11. Samsung Open Source Group 11
Build an IoT server
● Invest 5 EUR into RaspberryPI zero
● Learn a bit about Yocto (or ask me helper script)
● And build a tizen-distro image
source ./tizen-common-init-build-env build-common
BBLAYERS += ".../meta-raspberrypi"
BBLAYERS += ".../meta-oic"
IMAGE_INSTALL += " iotivity "
● Add virtual GPS server recipe and rebuild image

12. Samsung Open Source Group 12
Build IoT clients 1/2 : library
● Setup and configure GBS for :
– Tizen:2.4:Mobile for Z1
– Tizen:2.3.1:Wearable for Gear S2
– Tizen:3.0 for x86 or ARM
● Build dependencies 1st : (scons, boost...)
– git clone $URL -b ${branch} # (ie: tizen, tizen_2.4)
– gbs build -p ${profile} # (ie: tizen_mobile-armv7l)
● In the end : iotivity-*.rpm

13. Samsung Open Source Group 13
Build IoT clients 2/2 : app
● Create Native EFL app (C/C++)
– Using supported tizen-sdk
– For selected profile :
● Tizen:2.4:Mobile for Z1 or Tizen:2.3.1:Wearable for Gear S2
● Integrate IoTivity library :
– Unpack lib and headers from RPM in project
– Update Eclipse project settings (to link with IoTivity see wiki)
● Code your client using EFL (hint: elm_map)
● Deploy package to Device (*.tpk)

Shared Resource
● Once setup server owns resource's value:
– Updates it in a loop (from GPS or simulated)
● m_Representation.setValue("lat", m_lat);
● m_Representation.setValue("lon", m_lon);
● Once discovered client reflects the resource:
– Listen as observer (transparent)
– or polling on GET (using EFL timer)
– onChange(... const OCRepresentation &rep …)
● lat = rep.getValue<double>("lat");
● lon = rep.getValue<double>("lon");
