AN2646 - Application note

Smartcard interface example

39/43

To get file characteristics:

●

Select the file the characteristics of which are needed

●

Get the data returned after issuing the SelectFile APDU command by sending a

GETRESPONSE command

The IMSI file has 9 data bytes, so to run correctly the READ_BINARY commands, the

following parameters are used:

●

P1 = 0x00

●

P2 = 0x00

●

LE = 0x09

Figure 13. Get Response from a file at a specified path (example)

CLA=0xA0: to Select class GSM11

INS=0xA4: command to Select file

P1=0x00: not used

P2=0x00: not used

LC=0x02: Data file length

If SW1=0x00 Data: Address of the file or the folder to select

SW1 or SW1 and SW2 or ACK or NULL

CLA=0xA0: to Select class GSM11

INS=0xC2: command to get response

P1=0x00: not used

P2=0x00: not used

LE=SW2 : length of data to be returned

SW1 or SW1 and SW2 or ACK or NULL

GSM Card

Smartcard Interface

Receive the LE bytes from the card if SW1=0x00
