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)

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

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

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
