Until 2020


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


“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 ...


“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)


“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


Let's practice


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


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


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


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)


Client / Server Flow

2016-04-2714

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


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");

More Showcases

● Real world resources : Relay control– Using GPIO (MinnowMax, GENIVI, OSVehicle)

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
