Sorry the CLA and INS bytes were interchanged.
CLA sent is A0 and INS sent is A4

Post by designer
I have written a sim reader in Verilog. And testing it on FPGA Board
(SIM CARD is inserted on the slot provided on the BOARD).
I have got the ATR,PPS Response. Then I am sending Command(Select File
Command) Header .To which i am not getting a acknowledge.
I don't know what is the problem. Any ideas?
The ATR sequence i got is: 3B 17 11 1A 01 01 10 01 41 37.
Then the PPS Request/Response happened correctly : FF 10 11 FE
Then I sent a Select File (5 bytes) Command: A4(CLA) A0(INS) 00(P1)
00(P2) 02(P3/Length)
After this we didn't get a Acknowledge byte from the SIM. We didn't
get any byte at all.
Please help on this
Thanks,
