Hi,
You can find with the AN11876 an example to register a Java Desktop application (file attached in the PDF: TapLinxTest-Desktop.nxpzip).
You have to use the LibraryManager class and register your license file with the registerJavaApp method.

Hi,
Do you have a release date for the library version 1.8?
Only to know if it's planned for this end of year or if I need to wait 2021.
Thanks

Hi,
similar question on DesFIRE EV3 cards. I have DesFIRE EV3 provided by an official NXP partner. I can correctly read and write those cards, but the cardType when I read a card with the TapLinx library version 1.7 is "unknown card" and I can't find any DesfireEv3 function in your documentation.
Is a release planned which will contain features for this new chip?

Thanks

Hi,
It wasn't my idea to use your time to debug my own code, sorry for the incomprehension.
I only need help to understand what happens

I'm not convinced that my sample code can be considered as huge and elaborated, the only difference between my code and your test is that I try to read the datas after reading to check that everything is working well.

Thanks again for your help for all my previous answers,

Hi,
it works because your test is not similar to mine.
When I do a readData right after the writeData, it works well.
It's when I try to read later this file after an authentication that it breaks ("Read test" section in my example).

Thanks,

@taplinx-support Can you help us with our problem? It's really sad to not be able to upgrade our TapLinx library.
Thanks

Hi,
I did some new tests with the Taplinx library version 1.5

byte[] APP_MASTER_ID = {(byte) 0x00, (byte) 0x00, (byte) 0x00};

byte[] APP_TEST = {(byte) 0x01, (byte) 0x00, (byte) 0x01};



byte[] KEY_MASTER = {(byte) 0x01, (byte) 0x02,

        (byte) 0x03, (byte) 0x04, (byte) 0x05, (byte) 0x00, (byte) 0x00,

        (byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x00,

        (byte) 0x00, (byte) 0x00, (byte) 0x10, (byte) 0x11};



byte[] KEY_1 = {(byte) 0x01, (byte) 0x02,

        (byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x00,

        (byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x00,

        (byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x09};



byte[] blockA  = new byte[] {

        (byte) 0x14, (byte) 0x72, (byte) 0xA6, (byte) 0x3A,

        (byte) 0x7D, (byte) 0x3F, (byte) 0x44, (byte) 0x03,

        (byte) 0x99, (byte) 0x74, (byte) 0xDD, (byte) 0xB1,

        (byte) 0xC4, (byte) 0x28, (byte) 0xB0, (byte) 0xC8,

};



m_objDESFireEV1 = DESFireFactory.getInstance().getDESFireEV2(m_libInstance.getCustomModules());

m_objDESFireEV1.getReader().connect();

this.addLog("DESFire EV1 Reader connected");

m_objDESFireEV1.getReader().setTimeout(2000);



EV1ApplicationKeySettings.Builder appsetbuilder = new EV1ApplicationKeySettings.Builder();

EV1ApplicationKeySettings appsettings = appsetbuilder

        .setAppKeySettingsChangeable(true)

        .setAppMasterKeyChangeable(true)

        .setAuthenticationRequiredForFileManagement(true)

        .setAuthenticationRequiredForDirectoryConfigurationData(false)

        .setMaxNumberOfApplicationKeys(2)

        .setKeyTypeOfApplicationKeys(KeyType.TWO_KEY_THREEDES)

        .build();



m_objDESFireEV1.selectApplication(APP_MASTER_ID);



m_objDESFireEV1.createApplication(APP_TEST, appsettings);

addLog("App Test created");



m_objDESFireEV1.selectApplication(APP_TEST);

addLog("App Test selected");



m_objDESFireEV1.authenticate(0, IDESFireEV1.AuthType.Native, KeyType.THREEDES, keyDataDefault);

addLog("App Test Master authenticated");





SecretKeySpec keyDesWrite = new SecretKeySpec(KEY_1, "DESede");

KeyData keyDataDesWrite = new KeyData();

keyDataDesWrite.setKey(keyDesWrite);



SecretKeySpec keyDesMaster = new SecretKeySpec(KEY_MASTER, "DESede");

KeyData keyDataDesMaster = new KeyData();

keyDataDesMaster.setKey(keyDesMaster);



m_objDESFireEV1.createFile(0, new DESFireFile.StdDataFileSettings(IDESFireEV1.CommunicationType.Plain,

        (byte) 0x01,

        (byte) 0x00,

        (byte) 0x00,

        (byte) 0x00,

        32));



m_objDESFireEV1.writeData(0, 0, blockA);



addLog("File data written");



m_objDESFireEV1.authenticate(0, IDESFireEV1.AuthType.Native, KeyType.THREEDES, keyDataDefault);

addLog("KEY #0 App Authenticated");



m_objDESFireEV1.changeKey(1, KeyType.TWO_KEY_THREEDES, KEY_2KTDES_DEFAULT, KEY_1, (byte) 0x01);

addLog("KEY #1 App Changed");



m_objDESFireEV1.authenticate(0, IDESFireEV1.AuthType.Native, KeyType.THREEDES, keyDataDefault);

addLog("KEY #0 App Authenticated");



m_objDESFireEV1.changeKey(0, KeyType.TWO_KEY_THREEDES, KEY_2KTDES_DEFAULT, KEY_MASTER, (byte) 0x01);

addLog("KEY #0 App Changed");



// Read test

m_objDESFireEV1.selectApplication(APP_TEST);

addLog("APP Test Selected");



SecretKeySpec key1 = new SecretKeySpec(KEY_1, "DESede");

KeyData keyData1 = new KeyData();

keyData1.setKey(key1);



m_objDESFireEV1.authenticate(0, IDESFireEV1.AuthType.Native, KeyType.TWO_KEY_THREEDES, keyData1);

addLog("APP Test Key #1 Authenticated");



byte[] datasApp = m_objDESFireEV1.readData(0, 0, 16);

addLog("datas File 1 " + byteArrayToHexString(datasApp));

I always have an error : "InvalidResponseLengthException: Authentication Error" when I try to authenticate to read the datas at the line:

m_objDESFireEV1.authenticate(0, IDESFireEV1.AuthType.Native, KeyType.TWO_KEY_THREEDES, keyData1);

Thanks a lot for your answer, I will test it quickly.
I totally agree with you that AES is much way better, but unfortunately, our infrastructure contains a lot of readers which are not compatible with AES, and it's not easy to migrate them.

Thanks,

Hi,
for information, we use the library version 1.2, we can't move to a more recent version because of that problem.

I have the same problem with a CipherLab RS30 (Android 4.4) and a CipherLab RS31 (Android 7).

Thanks

Hi,
Yes, different applications
my tests are:
- trying to write/read with a different string to see if the same error occurs: it only happens with the ...BOC8
- trying to write/read the same string but with AES, the error doesn't occur

Thanks,
