Connected TIZEN

  1. 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. 2. Samsung Open Source Group 2 Until 2020
  3. 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. 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. 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. 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. 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. 8. Samsung Open Source Group 8 Let's practice
  9. 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. 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. 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. 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. 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. 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. 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. 16. Samsung Open Source Group 16 More Showcases
  17. 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. 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
