Nokia 6212 maximum data APDU send

[javaCard]

Hi, i'm developing a midlet that communicates with the nokia 6212 secure element, i can send/get APDUs to/from the secure element when the data length is less than 256 byte.
but one i want to send an apdu that contains data size 256 i get an IOexception : error communication 0x0f.
could you please help me to overcome this problem .
thx.
PS: i'm using iso 14443 for sending APDUs

PS:
- I'am working on a real device (not emulator)
- i can send APDUs that data length is less than 253, the exception is catched for APDUs that data length is more than 254.
- the exception is catched on the following command:

//data length is 256
private static final byte[] APDUCommand = {(byte) 0x00, (byte) 0x00 ,(byte) 0x03 ,(byte) 0x00 ,(byte) 0x00,(byte)0xff, (byte)0x0a,(byte) 0x1b,...,(byte)0x0c};
          response = secureElementConnection.exchangeData(APDUCommand);

Hallo,

but one i want to send an apdu that contains data size 256 i get an IOexception : error communication 0x0f.

256 is larger than one byte. Thus, you would need an extended length field in your APDU (i.e. Lc = '00 01 00' (hope this is the correct byte order)). At least with the Nokia 6131s that I have here, the ATR indicates that only single byte length fields are supported. I would expect this is the same with the Nokia 6212 as it uses the same secure element chip.

thank you for your feedback,
when i send the same apdu using jCOPshell i get status word :9000
for APDUs that data length is 254 or 255 i get the same exception

Hallo,

could you provide an example for such an APDU?

The data packet you provided so far does not seem like a proper APDU:

private static final byte[] APDUCommand = {(byte) 0x00, (byte) 0x00 ,(byte) 0x03 ,(byte) 0x00 ,(byte) 0x00,(byte)0xff, (byte)0x0a,(byte) 0x1b,...,(byte)0x0c};

Which is:

CLA = 0x00
INS = 0x00
P1 = 0x03
P2 = 0x00
Lc = 0xFF0A (= 65290 Byte)
DATA = 0x1B,...,0x0C

Or do I get something wrong here?

br,
Michael

my apdu has this form:

CLA :0x00
INS : 0x00
P1 :0x03
P2 :0x00
Lc : 0xff // Lc is one byte because i'm using JC2.2.1 which does not support extended APDU
// the complete data which length is 256
data : (byte) 0x1B , (byte) 0xD4, (byte) 0x9E, (byte) 0x40, (byte) 0x26, (byte) 0x4A, (byte) 0x3A, (byte) 0xB6, (byte) 0x1C, (byte) 0xBB, (byte) 0x57, (byte) 0x03, (byte) 0x3B, (byte) 0x44, (byte) 0x27, (byte) 0xE8, (byte) 0x56, (byte) 0x51, (byte) 0xF2, (byte) 0x7E, (byte) 0x10, (byte) 0xD7, (byte) 0xC9, (byte) 0x1B, (byte) 0x44, (byte) 0xEB, (byte) 0x49, (byte) 0xFD, (byte) 0xAE, (byte) 0x89, (byte) 0xEE, (byte) 0x9F, (byte) 0x82, (byte) 0xCB, (byte) 0x8C, (byte) 0x16, (byte) 0xA8, (byte) 0x65, (byte) 0x6B, (byte) 0x1B, (byte) 0xD6, (byte) 0x6C, (byte) 0xE9, (byte) 0x65, (byte) 0x0D, (byte) 0x0F, (byte) 0x78, (byte) 0x00, (byte) 0xC8, (byte) 0x03, (byte) 0x96, (byte) 0x26, (byte) 0x6A, (byte) 0x12, (byte) 0x9E, (byte) 0x7C, (byte) 0x56, (byte) 0x0c, (byte) 0x49, (byte) 0xED, (byte) 0x7B, (byte) 0x1b, (byte) 0x03, (byte) 0x38, (byte) 0x69, (byte) 0xB3, (byte) 0x7D, (byte) 0xF3, (byte) 0x22, (byte) 0x66, (byte) 0x5F, (byte) 0xF5, (byte) 0x0D, (byte) 0xC3, (byte) 0x34, (byte) 0x30, (byte) 0xCF, (byte) 0xA4, (byte) 0x20, (byte) 0x73, (byte) 0x8F, (byte) 0xAC, (byte) 0x93, (byte) 0x61, (byte) 0xDF, (byte) 0x6B, (byte) 0x61, (byte) 0x58, (byte) 0x64, (byte) 0x65, (byte) 0x9F, (byte) 0x03, (byte) 0x69, (byte) 0x9D, (byte) 0xA3, (byte) 0x6C, (byte) 0xDE, (byte) 0x6F, (byte) 0x38, (byte) 0x24, (byte) 0x61, (byte) 0x3C, (byte) 0xDD, (byte) 0xD4, (byte) 0x55, (byte) 0x49, (byte) 0x4B, (byte) 0x6A, (byte) 0x5F, (byte) 0x99, (byte) 0xA0, (byte) 0x5C, (byte) 0xD9, (byte) 0x99, (byte) 0x26, (byte) 0x90, (byte) 0x4E, (byte) 0x18, (byte) 0xFF, (byte) 0x53, (byte) 0x77, (byte) 0xF3, (byte) 0x3C, (byte) 0xD1, (byte) 0x79, (byte) 0x2F, (byte) 0x1A, (byte) 0x05, (byte) 0x93, (byte) 0xD4, (byte) 0x9E, (byte) 0x40, (byte) 0x26, (byte) 0x4A, (byte) 0x3A, (byte) 0xB6, (byte) 0x1C, (byte) 0xBB, (byte) 0x57, (byte) 0x03, (byte) 0x3B, (byte) 0x44, (byte) 0x27, (byte) 0xE8, (byte) 0x56, (byte) 0x51, (byte) 0xF2, (byte) 0x7E, (byte) 0x10, (byte) 0xD7, (byte) 0xC9, (byte) 0x1B, (byte) 0x44, (byte) 0xEB, (byte) 0x49, (byte) 0xFD, (byte) 0xAE, (byte) 0x89, (byte) 0xEE, (byte) 0x9F, (byte) 0x82, (byte) 0xCB, (byte) 0x8C, (byte) 0x16, (byte) 0xA8, (byte) 0x65, (byte) 0x6B, (byte) 0x1B, (byte) 0xD6, (byte) 0x6C, (byte) 0xE9, (byte) 0x65, (byte) 0x0D, (byte) 0x0F, (byte) 0x78, (byte) 0x72, (byte) 0xC8, (byte) 0x03, (byte) 0x96, (byte) 0x26, (byte) 0x6A, (byte) 0x12, (byte) 0x9E, (byte) 0x7C, (byte) 0x56, (byte) 0x2B, (byte) 0x49, (byte) 0xED, (byte) 0x7B, (byte) 0xF5, (byte) 0x03, (byte) 0x38, (byte) 0x69, (byte) 0xB3, (byte) 0x7D, (byte) 0xF3, (byte) 0x22, (byte) 0x66, (byte) 0x5F, (byte) 0xF5, (byte) 0x0D, (byte) 0xC3, (byte) 0x34, (byte) 0x30, (byte) 0xCF, (byte) 0xA4, (byte) 0x20, (byte) 0x73, (byte) 0x8F, (byte) 0xAC, (byte) 0x93, (byte) 0x61, (byte) 0xDF, (byte) 0x6B, (byte) 0x61, (byte) 0x58, (byte) 0x64, (byte) 0x65, (byte) 0x9F, (byte) 0x03, (byte) 0x69, (byte) 0x9D, (byte) 0xA3, (byte) 0x6C, (byte) 0xDE, (byte) 0x6F, (byte) 0x38, (byte) 0x24, (byte) 0x61, (byte) 0x3C, (byte) 0xDD, (byte) 0xD4, (byte) 0x55, (byte) 0x49, (byte) 0x4B, (byte) 0x6A, (byte) 0x5F, (byte) 0x99, (byte) 0xA0, (byte) 0x5C, (byte) 0xD9, (byte) 0x99, (byte) 0x26, (byte) 0x90, (byte) 0x4E, (byte) 0x18, (byte) 0xFF, (byte) 0x53, (byte) 0x77, (byte) 0xF3, (byte) 0x3C, (byte) 0xD1, (byte) 0x79, (byte) 0x2F, (byte) 0x1A, (byte) 0x0C


i'm using ISO 14443 for sending APDUs to the secure element

Lc : 0xff // Lc is one byte because i'm using JC2.2.1 which does not support extended APDU

Not with the example you showed before. There, your APDU clearly stated that you are using an extended (3 Byte) length field (first byte of Lc was zero). Anyways, as to my understanding you can't send more than 255 bytes of data in your command APDU without an extended length field.

hmm, yeah you're rigth for my first post that was wrong, i made an error in copying the apdu
the rigth apdu i'm sending is

//data length is 256
private static final byte[] APDUCommand = {(byte) 0x00, (byte) 0x00 ,(byte) 0x03 ,(byte) 0x00,(byte)0xff, (byte)0x0a,(byte) 0x1b,...,(byte)0x0c,(byte) 0x00};
response = secureElementConnection.exchangeData(APDUCommand);

the last 0x00 is for Le

[mroland]

Still I don't see how a Lc = 255 would allow you to send any data packet that is not 255 bytes long.
