Cannot connect with my device

[AppWerft]

Today I have installed the newest apk. On top title I see FTReaderStandard. I see: Hello World LibVersion 0.7.00.

I select PC/SC API and BT3.0. The list of devices remains empty. The same behavior I observe in the 3 other cases (Private API and BT and BTLE). The blue device with health card is nearby and the LED is flashing. Whats going wrong?

Second question: I can use the C++ Lib or the Jar. What is the difference, advantage/disadvantage?

OK, the issue with private API and C++ I have understood. My problem I cannot connect to reader.

I guess the demo app has no Location permission and that is the reason. Did forgot?

The C++ LIB is simulated with PC/SC API, which allows a user to build their App based on C/C++ directly without changing their source code.

And for Jar, this is simply API for the developer, easy to deploy.

You can choose one of them to use it And for the permission, I remember it already supported and the APK tested by our engineer, I will take a look tomorrow and back to you then, thanks

Now I have wrote an own app (with location permission) ;-). With this code I can find my reader, but after call of openReader() the app crashes.

My code:

case DK.BT3_NEW:
    BluetoothDevice dev1 = (BluetoothDevice) msg.obj;
    Log.d(LCAT, "Device found: " + dev1.getName());
    String[] readerNames;
    try {
        Log.d(LCAT, "try readerOpen() " );
        readerNames = ftReader.readerOpen(dev1);
        Log.d(LCAT, "readerOpened " +readerNames.length);

ca. 5 sec after the open command I see the code below on sonsole:

[DEBUG] :  CCIDScheme: (*init* (ftReaderInf ::FTReaderInf) (handler ::Handler)) #!void

My code follows your demo app. I cannot understand why the connection cannot established. The bonding state is BONDED.

This is my repo. The code realizes a module for Titanium. ;-)

more details:

com.ftsafe.readerScheme.FTReader.readerOpen()

is a switch, depending on device type a new CCIDSchema will instantiated, in my case:

new CCIDScheme(new BT3(paramContext, mHandler), mHandler)

This BT3 constructor get a new BTdefaultadapter, registers a receiver and starts a thread. As the result I can see the device name FT__3481F4048A73.

Now I try to open the device. readerOpen tries ccidScheme.readerOpen() and uses the same ccid object as the finder. My question: where is CCIDScheme.scm and why timeout?

Best! Rainer

The error message read failed, socket might closed or timeout is not part of private jar, it seems to come from Bluetooth stack:

Yes, we know this issue, this is not a library issue, will check with our team with our solution, the android engineer got business trip, should be back this Wednesday, will keep you update, thanks

Thanks for you support. First I see an issue with manifest. If there is no entry for LOCATION_PERMISSION, then I cannot enable in system configuration. In my app I have added this entry. Therefore I "see" the device in handler. But I cannot open.

This method ft_open() in com.ftsafe.bt3.BT3.java makes trouble.

public void ft_open(Object paramObject) throws Bt3Exception {
    final String FTUUID = "00001101-0000-1000-8000-00805F9B34FB";
    if (paramObject == null) {
      throw new Bt3Exception("device == null");
    }
    btAdapter.cancelDiscovery();
    try {
      if ((btSocket != null) 
            && (btSocket.isConnected()) 
            && (btDevice.getAddress().equals(((btDevice)paramObject).getAddress()))) {
        showLog("donaaaaaaaaaaaaaaaaaaaaaa");
        return;
      }
      btDevice = ((BluetoothDevice)paramObject);
      if (btSocket != null) {
        btSocket.close();
     }
      btSocket = btDevice.createInsecureRfcommSocketToServiceRecord(UUID.fromString(FTUUID));
      btSocket.connect();
    }
    catch (Exception localException) {
      throw new Bt3Exception(localException.getMessage());
    }
}

same issue with https://github.com/FeitianSmartcardReader/FEITIAN_MOBILE_READERS/issues/9

Update the manifest file, problem solved.
