Run the example

  1. Install and run the device gateway
  2. Download the Java client library
  3. Copy the root certificate of the device gateway to your working directory. As default, the certificate(ca.crt) resides in cert of the installation directory.
  4. The example uses Gradle for its project. You can change the build.gradle file as needed.

  5. Change the gateway and the device information in src/main/java/com/supremainc/sdk/example/tna/test/TNATest.java as needed.

     // the path of the root certificate
 private static final String GATEWAY_CA_FILE = "cert/gateway/ca.crt";

 // the address of the gateway
 private static final String GATEWAY_ADDR = "192.168.0.2";
 private static final int GATEWAY_PORT = 4000;

 // the ip address of the target device
 private static final String DEVICE_ADDR = "192.168.0.110"; 
 private static final int DEVICE_PORT = 51211;

  6. Build.

     ./gradlew installDist

  7. Run.

     ./build/install/java/bin/tnaTest

1. Connect to the gateway and the device

The example assumes you use the device gateway. For the master gateway or other connection options, refer to the Connect or ConnectMaster examples.

  GatewayClient client = new GatewayClient();
  client.connect(CA_FILE, GATEWAY_ADDR, GATEWAY_PORT);

  ConnectInfo connInfo = ConnectInfo.newBuilder().setIPAddr(DEVICE_ADDR).setPort(DEVICE_PORT).setUseSSL(DEVICE_USE_SSL).build();
  int deviceID = userTest.connectSvc.connect(connInfo);

2. Test the T&A configuration

There are several options you can configure related to the T&A functions. The example shows how to configure some of these options and let you check the results.

  // (1) BY_USER
  String[] labels = {"In", "Out", "Scheduled In", "Fixed Out"};
  TNAConfig newConfig = TNAConfig.newBuilder().setMode(Mode.BY_USER).addAllLabels(Arrays.asList(labels)).build();
  tnaSvc.setConfig(deviceID, newConfig);

  System.out.printf("(1) The T&A mode is set to BY_USER(optional). You can select a T&A key before authentication. Try to authenticate after selecting a T&A key.\n\n");
  KeyInput.pressEnter(">> Press ENTER if you finish testing this mode.\n");

  // (2) IsRequired
  tnaSvc.setConfig(deviceID, newConfig.toBuilder().setIsRequired(true).build());

  System.out.printf("(2) The T&A mode is set to BY_USER(mandatory). Try to authenticate without selecting a T&A key.\n\n");
  KeyInput.pressEnter(">> Press ENTER if you finish testing this mode.\n");

  // (3) LAST_CHOICE
  tnaSvc.setConfig(deviceID, newConfig.toBuilder().setMode(Mode.LAST_CHOICE).build());

  System.out.printf("(3) The T&A mode is set to LAST_CHOICE. The T&A key selected by the previous user will be used. Try to authenticate multiple users.\n\n");
  KeyInput.pressEnter(">> Press ENTER if you finish testing this mode.\n");

  // (4) BY_SCHEDULE
  Integer[] scheduleIDs = { 0, 0, 1 }; // Always for KEY_3(Scheduled_In)
  tnaSvc.setConfig(deviceID, newConfig.toBuilder().setMode(Mode.BY_SCHEDULE).addAllSchedules(Arrays.asList(scheduleIDs)).build());

  System.out.printf("(4) The T&A mode is set to BY_SCHEDULE. The T&A key will be determined automatically by schedule. Try to authenticate without selecting a T&A key.\n\n");
  KeyInput.pressEnter(">> Press ENTER if you finish testing this mode.\n");

  // (5) FIXED
  tnaSvc.setConfig(deviceID, newConfig.toBuilder().setMode(Mode.FIXED).setKey(Key.KEY_4).build());

  System.out.printf("(5) The T&A mode is set to FIXED(KEY_4). Try to authenticate without selecting a T&A key.\n\n");
  KeyInput.pressEnter(">> Press ENTER if you finish testing this mode.\n");

3. Get the T&A logs

You can read the log records with T&A key information using TNA.GetTNALog. To get the label of the key, you have to look up the TNAConfig.labels.

  List<TNALog> events = tnaSvc.getTNALog(deviceID, firstEventID, 0);

  // ...

  public String getTNALabel(Key key, TNAConfig config) {
    if(config.getLabelsCount() > key.getNumber() - 1) {
      return String.format("%s(%s)", config.getLabels(key.getNumber() - 1), key);
    } else {
      return String.format("%s", key);
    }
  }

You can also subscribe to an event stream for receiving realtime events.

  CancellableContext monitoringCtx = Context.current().withCancellation();
  Context prevCtx = monitoringCtx.attach();

  eventSvc.setCancellableContext(monitoringCtx);

  SubscribeRealtimeLogRequest subscribeRequest = SubscribeRealtimeLogRequest.newBuilder().setQueueSize(MONITORING_QUEUE_SIZE).addDeviceIDs(deviceID).build();
  Iterator<EventLog> eventStream = eventSvc.getStub().subscribeRealtimeLog(subscribeRequest);

  while(eventStream.hasNext()) {
    EventLog eventLog = eventStream.next();
    eventSvc.getEventCallback().handle(eventLog);
  }
