Second try. (I already sent this mail yesterday, but it did not appear in the mailinglist. I do not know why. Maybe because I attached a file (a patch)) Hi all, This is my first post to the OpenBSC mailinglist. I had a problem with the latest pysim version giving errors while trying to program 2G (Fake)MagicSIM cards. This had worked fine in the past with an older release from 2011. I tried al lot of versions in between. I was finally able to narrow it down to the commit that broke compatibility with (fake)magicsim: http://cgit.osmocom.org/pysim/commit/pySim/commands.py?id=8c1b33c439fef423c… The comment with this comit is: "Do not return the FCI information while selecting a file The sysmoUSIM-SJS1 card does not support returning the FCI information. Plus, the FCI information are not used anyway." If I revert the change with attached patch, it works again. But it may break sysmoUSIM-SJS1 compatibility. I am not sure on how to test whether the programming of sysmoUSIM-SJS1 still works fine and if the SIMS themselves then will still work as expected with OpenBSC or OpenBTS or OpenAirinterface. If the code needs to stay in for sysmoUSIM-SJS1 then we probably need somehing like the pseudocode below: if carttype is fakemagicsim: "a4000002" elif cardtype is sysmoUSIM-SJS1: "a4000C02" else: #What should be the default for the other cards? Or is there another solution?
