SIM card related Projects » pySim

For some reason, pySim-prog.py fails to program a SIM card when using Python 3.

Using PC/SC reader (dev=0) interface
Ready for Programming: Insert card now (or CTRL-C to cancel)
Autodetected card type: sysmoUSIM-SJS1
Generated card parameters :
 > Name     : Osmocom
 > SMSP     : e1ffffffffffffffffffffffff068100095155f5ffffffffff000000
 > ICCID    : [REMOVED]
 > MCC/MNC  : 901/70
 > IMSI     : 901700000025647
 > Ki       : [REMOVED]
 > OPC      : [REMOVED]
 > ACC      : None
 > ADM1(hex): [REMOVED]

Card programming failed with an execption:

At the same time, reading a SIM card works just fine. Switching back to Python 2 makes pySim-prog.py work again.

I grabbed debug output of pcscd using the following command:

$ sudo LIBCCID_ifdLogLevel=0x0007 pcscd -fd | tee /tmp/pcscd.log

Please seee attached files and the difference between them.
