Run the example

  1. Install and run the device gateway
  2. Download the C# 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 grpc-dotnet. You can change the example/tna/test/test.csproj file as needed.

  5. Change the gateway and the device information in example/tna/test/Program.cs as needed.

     // the path of the root certificate
 private const string GATEWAY_CA_FILE = "../../../../cert/gateway/ca.crt";

 // the address of the gateway
 private const string GATEWAY_ADDR = "192.168.0.2";
 private const int GATEWAY_PORT = 4000;

 // the ip address of the target device
 private const string DEVICE_ADDR = "192.168.0.110";
 private const int DEVICE_PORT = 51211;

  6. Build and run.

     cd example/tna/test
 dotnet run

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 gatewayClient = new GatewayClient();
  gatewayClient.Connect(GATEWAY_CA_FILE, GATEWAY_ADDR, GATEWAY_PORT);

  var connectInfo = new ConnectInfo{ IPAddr = DEVICE_ADDR, Port = DEVICE_PORT, UseSSL = USE_SSL };
  uint devID = userTest.connectSvc.Connect(connectInfo);

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
  var newConfig = new TNAConfig{ Mode = Mode.ByUser, Labels = {"In", "Out", "Scheduled In", "Fixed Out"} };
  tnaSvc.SetConfig(deviceID, newConfig);

  Console.WriteLine("(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." + Environment.NewLine);
  KeyInput.PressEnter(">> Press ENTER if you finish testing this mode." + Environment.NewLine);

  // (2) IsRequired
  newConfig.IsRequired = true;
  tnaSvc.SetConfig(deviceID, newConfig);

  Console.WriteLine("(2) The T&A mode is set to BY_USER(mandatory). Try to authenticate without selecting a T&A key." + Environment.NewLine);
  KeyInput.PressEnter(">> Press ENTER if you finish testing this mode." + Environment.NewLine);

  // (3) LAST_CHOICE
  newConfig.Mode = Mode.LastChoice;
  tnaSvc.SetConfig(deviceID, newConfig);

  Console.WriteLine("(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." + Environment.NewLine);
  KeyInput.PressEnter(">> Press ENTER if you finish testing this mode." + Environment.NewLine);

  // (4) BY_SCHEDULE
  newConfig.Mode = Mode.BySchedule;
  newConfig.Schedules.AddRange(new uint[]{ 0, 0, 1 }); // Always for KEY_3(Scheduled_In)
  tnaSvc.SetConfig(deviceID, newConfig);

  Console.WriteLine("(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." + Environment.NewLine);
  KeyInput.PressEnter(">> Press ENTER if you finish testing this mode." + Environment.NewLine);      

  // (5) FIXED
  newConfig.Mode = Mode.Fixed;
  newConfig.Key = Key._4;
  tnaSvc.SetConfig(deviceID, newConfig);

  Console.WriteLine("(5) The T&A mode is set to FIXED(KEY_4). Try to authenticate without selecting a T&A key." + Environment.NewLine);
  KeyInput.PressEnter(">> Press ENTER if you finish testing this mode." + Environment.NewLine);

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.

  var events = tnaSvc.GetTNALog(deviceID, firstEventID, 0);

  // ...

  private string GetTNALabel(Key key, TNAConfig config) {
    if(config.Labels.Count > (int)key - 1) {
      return string.Format("{0}(KEY{1})", config.Labels[(int)key - 1], key);
    } else {
      return string.Format("KEY{0}", key);
    }      
  }

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

  var enableRequest = new EnableMonitoringRequest{ DeviceID = deviceID };
  eventClient.EnableMonitoring(enableRequest);

  var subscribeRequest = new SubscribeRealtimeLogRequest{ DeviceIDs = {deviceID}, QueueSize = MONITORING_QUEUE_SIZE };
  var call = eventClient.SubscribeRealtimeLog(subscribeRequest);

  cancellationTokenSource = new CancellationTokenSource();

  ReceiveEvents(this, call.ResponseStream, cancellationTokenSource.Token);

  static async void ReceiveEvents(EventSvc svc, IAsyncStreamReader<EventLog> stream, CancellationToken token) {
    while(await stream.MoveNext(token)) {
      var eventLog = stream.Current;

      if(svc.callback != null) {
        svc.callback(eventLog);
      } 
    }
  }
