11. Exercise 2 Install the Java Embedded Runtime Install RaspbianDebian Wheezy (September 2014 Version) including JDK 8* or install Java Embedded (oracle-java8-jdk) sudoapt-get update sudoapt-get install oracle-java8-jdk sudochmod +s /usr/lib/jvm/jdk-8-oracle-arm-vfp-hflt/bin/java • java –version • java version "1.8.0" • Java(TM) SE Runtime Environment (build 1.8.0-b132) • Java HotSpot(TM) Client VM (build 25.0-b70, mixed mode) * Not part of tutorial. Navigate to http://www.raspberrypi.org/downloads and choose RaspbianDebian Wheezy Version September 2014

12. Exercise 2 Configure Java Embedded Runtime • Oracle Java SE 8 • Java Programming Language • Lambda Expressions • Method references • Default methods • Repeating Annotations, Type Annotations • Compact Profiles - predefined subsets of the Java SE platform

14. Exercise 3 Configure the “lookup service” Running a Simple Jini Lookup Service with Java Embedded • Provides the infrastructure for the Service-object-oriented architecture (SOOA). • Locating services is done through a lookup service • Services try to contact a lookup service (LUS), either by unicast interaction, when it knows the actual location of the lookup service • Clients use the lookup service to retrieve a proxy object to the service • Endpoint Registry

15. Exercise 3 Calling the Lookup Server // … // liquidLevelProbe has been discovered // … if (!liquidLevelProbeDiscoveredFlag) { System.out.println("liquidLevelProbe discovered"); joinLookUpService(LIQUID_LEVEL_PROBE); liquidLevelProbeDiscoveredFlag = true; }

17. Exercise 4 Add liquid level sensor using IoT Auto-Join Add an eTape liquid level and thermometer sensors to Raspberry Pi • Writing a IoT Endpoint proxy object • Registering the IoT Endpoint proxy object with the IoT Gateway LUS • User plugs in the liquid level sensor to the Raspberry Pi and it is auto-discovered • Running the liquid level sensor java –jar iot-liquid-level-sensor.jar

18. Exercise 4 Add liquid level sensor using IoT Auto-Join // Open RandomAccessFile handle to each GPIO port raf= new RandomAccessFile("/sys/class/gpio/gpio" + gpioInputChannel + "/value", "r"); raf.seek(0); raf.read(inBytes); inLine = new String(inBytes); // Endpoint: liquidLevelProbe if (inLine.startsWith("1")) { commandChannels[1].write(GPIO_ON); commandChannels[1].flush(); if (!liquidLevelProbeDiscoveredFlag) { System.out.println("liquidLevelProbe discovered"); joinLookUpService(LIQUID_LEVEL_PROBE); liquidLevelProbeDiscoveredFlag = true; }

19. Exercise 4 Add thermometer using IoT Auto-Join Add a Go!Temp Temperature Probe to Your Raspberry Pi • Writing a IoT Endpoint proxy object • Registering the IoT Endpoint proxy object with the IoT Gateway LUS • User plugs in Go!Temp Temperature Probe to the Raspberry Pi and it is auto-discovered • Run the temperature probe • java –jar iot-temp-probe.jar

20. Exercise 4 Add thermometer using IoT Auto-Join // Endpoint: tempProbe File tempProbeCheck = new File("/dev/ldusb0"); if (tempProbeCheck.exists()) { commandChannels[0].write(GPIO_ON); commandChannels[0].flush(); if (!tempProbeDiscoveredFlag) { System.out.println("tempProbe discovered"); joinLookUpService(TEMP_PROBE); tempProbeDiscoveredFlag = true; }

22. Exercise 5 Set-up data analytics on the Gateway Running Simple Analytics on the Gateway • Data Analytics on the Gateway • Local Analytics can be used to monitor the local devices and sensors • Local Java algorithms to watch for triggers • User is notified for anomalous events • Examining Analytics Running on the Raspberry Pi • Browse the Gateway URL for demo

23. Exercise 5 Set-up data analytics on the Gateway static void tempProbeAdapter() { System.out.println("liquidLevelProbe Adapter: storing data locally " + "and sending data to IoT Cloud"); // Store data locally // Upload data to the IoT Cloud CloudStorageConfigmyConfig = new CloudStorageConfig(); myConfig.setServiceName("myService-myIdentityDomain") .setUsername("myUsername") .setPassword("myPassword".toCharArray()) .setServiceUrl("https://storage.us2.oraclecloud.com"); CloudStoragemyConnection = CloudStorageFactory.getStorage(myConfig); FileInputStreamfis = new FileInputStream("iotcloud-liquid-level-data.txt"); myConnection.storeObject("MyContainer", "iotcloud-liquid-level-data.txt", "text/plain", fis); // Process data }

24. Exercise 5 Set-up data analytics on the Cloud Running a Global Analytics on the Cloud • Data Analytics in the Cloud • Global Analytics can be used to monitor the worldwide sets of devices and sensors • Global ruleset to watch for triggers • Administrator is notified for anomalous events • Examining Analytics Running in the Cloud • Browse the Cloud URL • http://iotcloud.x10host.com/autojoin/

25. Exercise 5 Set-up data analytics on the Cloud static void tempProbeAdapter() { System.out.println("liquidLevelProbe Adapter: storing data locally " + "and sending data to IoT Cloud"); // Store data locally // Upload data to the IoT Cloud CloudStorageConfigmyConfig = new CloudStorageConfig(); myConfig.setServiceName("myService-myIdentityDomain") .setUsername("myUsername") .setPassword("myPassword".toCharArray()) .setServiceUrl("https://storage.us2.oraclecloud.com"); CloudStoragemyConnection = CloudStorageFactory.getStorage(myConfig); FileInputStreamfis = new FileInputStream("iotcloud-liquid-level-data.txt"); myConnection.storeObject("MyContainer", "iotcloud-liquid-level-data.txt", "text/plain", fis); // Process data }
