SIM card related Projects » pySim

As far as I can see we already something like this implemented for quite some time now. As it seems, the log output is from an older version of pySim.

To be sure I have reproduced the situation which is shown in the log:

$ ./mksim_sja2.sh 
Using PC/SC reader number 2
Ready for Programming: Insert card now (or CTRL-C to cancel)

I think we may close this ticket.

You're judging by a specific case in which the Status Word would be '63Cx'. Looking more carefully at the source code:

570     def _chv_process_sw(self, op_name: str, chv_no: int, pin_code: Hexstr, sw: SwHexstr):
571         if sw_match(sw, '63cx'):
572             raise RuntimeError('Failed to %s chv_no 0x%02X with code 0x%s, %i tries left.' %
573                                (op_name, chv_no, b2h(pin_code).upper(), int(sw[3])))
574         elif (sw != '9000'):
575             raise SwMatchError(sw, '9000')

I can see it's still possible that one would get an error like in the ticket description if the status word ('6983' for instance) does not match '63Cx'.
The line numbers in the ticket description match the current code, see: https://cgit.osmocom.org/pysim/tree/pySim/commands.py#n575.

Also, I would guess this is not only about CHV errors, but also applies to other scenarios in which SW mismatch can occur?
