– Embedded sensor in car (demo: I²C sensor)
● 2: Get position from satellites (GPS, Galileo)
– From: car, mobile or any (demo: simulated)
● 3: Send notice to Internet (Cloud)
– Using mobile data
– 4: Forward information to city services (pull or push)
● 5: Agent is assigned
– 6: to fix defective light
● 7: he can also check “open data” base from his mobile

Open Connectivity Foundation
● “Providing the software Linking the Internet of Things”
– Creating a specification, based on open standards:
● Resource based, RESTful architecture (Stateless. client/server...)
● IETF, CoAP protocol (Web on UDP), CBOR (JSON in binary)...
– Sponsoring an open source reference implementation (IoTivity)
● Join 190+ members to
– Discuss specification, propose RFC
– Test products in Plugfests & certify them
– Propose new data models (OneIoTA.org)

Samsung Open Source Group 12 https://fosdem.org/2017/schedule/event/iot_iotivity/Samsung Open Source Group
Welcome to JavaScript developers !
● IoT is not reserved for embedded (few) developers (many)
● NodeJS a run time environment of choice for prototyping
– Huge community = Consistent repository of many modules
● to be installed using node package manger
– Packaged for many OSes: GNU/Linux, Tizen, Yocto
● IoTivity-node: npm install iotivity-node
– binds IoTivity CSDK (Core Library) to Javascript
– Of course is interoperable with native servers or clients
● Let's get started, with a yocto distro with node, npm, iotivity-node
Samsung Open Source Group 13 https://fosdem.org/2017/schedule/event/iot_iotivity/Samsung Open Source Group
BH1750 Digital Light Sensor
● Illuminance: [1 – 65535] lx
– Datasheet: bh1750fvi-e.pdf
● Uses I²C bus interface
– 5P: GND, ADD (to GND), SDA, SCL, VCC
– Check presence:
● /dev/i2c-1 on Raspberry Pi2
● I2cdetect -y 1 : will tell the address to use
● NodeJS package(s) available:
– https://www.npmjs.com/search?q=bh1750
– npm install bh1750
// https://www.npmjs.com/package/bh1750
var BH1750 = require('bh1750');
var device = '/dev/i2c­1';
var address = 0x23;
var options = { 
    address: address, device: device,
    command: 0x10, // 1 lx resolution
    length: 2
};
var sensor = new BH1750( { options } )
sensor.readLight(function(value){
   console.log(value);
   // emit('update', value);
});
Samsung Open Source Group 14 https://fosdem.org/2017/schedule/event/iot_iotivity/Samsung Open Source Group
OCF: Resources Data Models: oneIoTa
● Resource is identified by an URI
– Composed of properties
● Declared by a ResourceType
– Operations: CRUD+N
● Create, Read, Update, Delete+ Notify
● Use existing known resource models
– From oneIoTa.org repository
– Ie: sensors, geolocation...
● Or create new ones (new names)
– Share for interoperability
● http://www.oneiota.org/revisions/1863
● oic.r.sensor.illuminance.json
● /* … */ "definitions": {
  "oic.r.sensor.illuminance": {
    "properties": {
      "illuminance": {
        "type": "number",
        "readOnly": true,
        "description":
    "Sensed luminous flux in lux."
}  }  } /* … */ 
Samsung Open Source Group 15 https://fosdem.org/2017/schedule/event/iot_iotivity/Samsung Open Source Group
IoTivity-node Server notifies
● Intialize server and register resource:
iotivity 
= require("iotivity­node/lowlevel");
iotivity.OCInit(null, 0, OC_SERVER);
iotivity.OCCreateResource(
   handleReceptacle,
   resourceType,
   OC_RSRVD_INTERFACE_DEFAULT,
   "/IlluminanceResUri", // URL
   handleEntity,
   OC_DISCOVERABLE | OC_OBSERVABLE);
● resourceType define Payload's data and format:
– // ie: "oic.r.sensor.illuminance"
– { “illuminance”: 42 } 
●
handleEntity Is a callback on client(s) requests
– Register observers
– Respond to requests (GET, POST, PUT)
● notify(value) to observers using:
– iotivity.OCNotifyListOfObservers
● Integrate ambient sensor by trapping events:
– source.on("update", notify )
● Processing loop:
setInterval(function(
 {iotivity.OCProcess();}, 1000);
Samsung Open Source Group 16 https://fosdem.org/2017/schedule/event/iot_iotivity/Samsung Open Source Group
IoTivity-node Client observes
var client = require("iotivity­node").client;
client.on("resourcefound", function(resource) {
    if ("/IlluminanceResUri" === resource.resourcePath){
        resource.on("update", function(resource) {
            console.log(JSON.stringify(resource.properties)); 
            // OR update UI, forward elsewhere?
        };
    }
});
client.findResources().catch( function(error) { process.exit(1); } );
