BackupData file write and read issue

Forum / MIFARE SDK / BackupData file write and read issue

    Hi

    In an application with AES encryption I have created a BackupData file with CommunicationType.MACed (same conditions with Enciphered).

    Then i execute writeData after authentication and then commitTransaction.

    No exception so far.

    Now when i readData (after authentication) then all zeros are returned no matter what data i write in earlier step.

    All the steps are executed without any exception.

    I am spinning my head for a week now trying to under what i might be missing.

    Please help
