  1. Samsung Open Source Group 1 connected with Open Source Innovation

    Spring 2016 <2016-05-03> Philippe Coval Samsung Open Source Group / SRUK philippe.coval@osg.samsung.com
  2. Samsung Open Source Group 2 Until 2020

  3. Samsung Open Source Group 3 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
  8. Samsung Open Source Group 8 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)
  14. Samsung Open Source Group 14 Client / Server Flow 2016-04-27

    14 OCPlatform::Configure(OC::PlatformConfig ) OCPlatform::registerResource(...) ... OC::EntityHandler(OCResourceRequest) { switch(getRequestType) { case 'GET' : ... OCPlatform::sendResponse(...);; case 'PUT' : ... OCPlatform::sendResponse(...); OCPlatform::notifyAllObservers();; }} OCPlatform::findResource(...) // Multicast for discovery:(UDP) OCPlatform::Configure(OC::PlatformConfig ) OC::OCResource::put(...) OC::PutCallback(...) OC::OCResource::get(...) OC::GetCallback(...) IoTivity Server (on Tizen 3) IoTivity Client(s) (on Tizen 2) OC:ObserveCallback(...) IP Network
  15. Samsung Open Source Group 15 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");
  16. Samsung Open Source Group 16 More Showcases

  17. Samsung Open Source Group 17 More Showcases • Real world

    resources : Relay control – Using GPIO (MinnowMax, GENIVI, OSVehicle) • https://vimeo.com/164000646#tizen-genivi-20160424rzr • Check Automotive WIP about Bridging RVI to OCF too
  18. Samsung Open Source Group 18 Summary • You can build

    your own full FLOSS IoT device – Running on and OS – On accessible developer devices (SBC) • Interact with commercialized products – Through Native apps – Developed with Tizen SDK – Linked with IoTivity • Or any other devices of your dreams
