   IoT ? You said ?
   ●
   “I” like Interoperability
   – Do we want all devices exposed to the Internet ?
   – Local connectivity between devices
   – 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

   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

   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)

    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("lat");
    ●
    lon = rep.getValue("lon");
