Re: javax.smartcardio error: Could not obtain response

So as what has been mentioned above, even for APDU commands that are sent without any data attached. You have to send a dummy data attached to it.

At the applet side, do a setIncomingAndReceive()
first and ignore the retrieved dummy data. then proceed with your response.

Re: How to catch the reason of error 6F00

mypin.update(buffer, buffer[ISO7816.OFFSET_CDATA], buffer[ISO7816.OFFSET_LC]);

The second parameter of OwnerPIN.update() is the starting offset of your pin in the given array.
In your example command, your are using the content of the APDU buffer at offset 5. This may be the problem.

Re: How to catch the reason of error 6F00

You may also try to add a try/catch clause to confirm which exception is thrown.

Re: How to catch the reason of error 6F00

0x6F00 is usually returned by the card when an exception is not caught.
Could you show us your process method ?

Re: How to catch the reason of error 6F00

Your problem may be caused by this line:

byte byteRead = (byte) apdu.setIncomingAndReceive();

Re: SCardTransmit returns "invalid parameters ERROR 80100004"

Another thing is Byte[] vectorSend command maybe wrong. It seems that LC is wrong.

You can try to send
>> 0x00, 0xa4, 0x04, 0x00, 0x02, 0x6f, 0x65, 0x00

Do you have SCARD_PROTOCOL_T1 in your SCardConnect call?

Re: Get 6F00 when sending INS_START command

Note that there is break; operators in a switch-case statement. switch(apdu_buffer[ISO7816.OFFSET_INS]) { case INS_START: // When start command is received do: // Create challenge and write it into apdu buffer and challenge_card_stored array as reference challenge_card_sent.generateData(apdu_buffer,...

Re: Exception 0x8010002F, why?

0x60 can not be used as SW1 status word, which results in the communication error. It will not request any action on data transfer.
