 Posted: Tue Feb 15, 2011 4:18 pm Post subject: Correct usage of select() and sim() |
 |
|
Hello,
I am trying to use select() and sim() to read the IMSI from the SIM card.
I have the following code:
u8 PROGMEM ef_imsi_path[] = { 0x3F, 0x00, 0x7F, 0x20, 0x6F, 0x07 };
void read_imsi(u8* imsibuf)
{
u8 path[6];
memcpy(path, ef_imsi_path, 6);
select(ef_imsi_path, 3);
sim(ME_CMD_READ_BINARY, 0x00, 0x00, 0x09, imsibuf);
select(0, 0);
}
From here, imsibuf contains data that changes each time I boot, but it always start with 6981.
NB: This function is called from a stk_thread called in ACTION_FIRST_STK
Is 6981 the return code from the card? If so, it means "Command incompatible with file structure".
What's happening? |

| Here trace of whole ME-TL2-SIM would help to see all picture. Btw. you init path but then don't use it, is it what you want? |

I heard about a L1 debug kernel on this forum, is it available somewhere?
You can send it to the e-mail address associated with this account.

Yes sorry, the code I am actually using is :
| Code: |
u8 PROGMEM ef_imsi_path[] = { 0x3F, 0x00, 0x7F, 0x20, 0x6F, 0x07 };
void read_imsi(u8* imsibuf)
{
u8 path[6];
memcpy(path, ef_imsi_path, 6);
select(path, 3);
sim(ME_CMD_READ_BINARY, 0x00, 0x00, 0x09, imsibuf);
select(0, 0);
} |
I have tried with two different SIM cards from different operators and the problem is the same. |

I have received the L1 debug kernel and have tried it.
It seems to show that there is indeed a problem with the kernel code.
Dbg output:
| Code: | 3f007f206f07
TO SIM: 00 a4 00 00 02
TO SIM: 3f 00
FROM SIM: 6b 00
TO SIM: 00 b0 00 00 09
FROM SIM: 69 81
TO SIM: 00 a4 00 00 02
TO SIM: 3f 00
FROM SIM: 6b 00
6981e5f1fbdfbf5f45
|
Associated code:
| Code: | u8 PROGMEM ef_imsi_path[6] = { 0x3F, 0x00, 0x7F, 0x20, 0x6F, 0x07 };
void readSim_IMSI (u8* imsi)
{
u8 path[6];
u8 i;
memcpy(path, ef_imsi_path, 6);
for (i=0; i<6; i++)
dbch(path[i]);
dbc('\n');
select(path, 3);
sim(ME_CMD_READ_BINARY, 0x00, 0x00, 0x09, imsi);
select(0, 0);
for (i=0; i<9; i++)
dbch(imsi[i]);
dbc('\n');
}
|
Please advise on what to do |

| Can you post a longer trace, from reset to the time phone connects to the network? (Remove sms/phonebook related apdus.) |

| Eeeh I answered on your email that if you could send us the whole debug from reset. This is related to what SIM (USIM resp.) is used so your log is needed. |
