There appears to be numerous references to "decrease the buffer in the
firmware" to workaround the problem of losing bytes... but
can you clarify which buffer to decrease, in which source file?
I am guessing it's the req_ctx.c / req_ctx.h?
Thanks
Hi!
I really don't want to feel this list to be abused for advertisements,
but in this case I'm sure it is of actual help to a number of people on
this list:
The sysmocom web shop finally has a 3FF (micro-SIM) adapter cable
available: http://shop.sysmocom.de/products/simtrace-fpc-3ff
Please note that (as opposed to the regular mini-SIM) we only have one
of the possible four orientations available. This is primarily due to
the high manufacturing cost of low-volume flexible PCB projects.
We would like to hear from you
1) if you need this adapter in different orientation (which, for which
phone)
2) for which phone model you have used this new 3FF adapter successfully
3) what kind of problems you may have encountered using it.
Thanks to Kevin Redon for doing the PCB layout of this part. It is
freely available as part of the simtrace.git repository since commit
eee3243ddaa9e13bc7509a962fade8636b6ed2ab.
On a related note: For nanoSIM, I think we would have to go for
dual-layer PCB with vias placed inside the actual card contact pads.
This will make production cost even more expensive than the microSIM
adapter. So unless there's significant interest in a nanoSIM adapter,
it's unlikely that we'd have some made. Please let us know if you
absolutely want one, and if you're happy to pay even more (e.g. 25-30
EUR) for only that adapter.
Regards,
Harald

Does anyone have a Terminal Profile handy for an iPhone 4 or 4S? I
dont' have the microSIM SimTrace adapter, and the database here:
https://terminal-profile.osmocom.org/ doesn't appear to have been
updated in a while.
Thanks!
Hi List,
I'm running into the following command sequence in a Nexus One Android
2.3 phone:
C-APDU:80F20001FF (STATUS)
R-APDU:6C12 (Incorrect Parameter P3)
After which the phone power-cycles the card.
I'm wondering whether this is is desired behavior, or if it's a bug in
the new MITM code.
Phone seems to reset the card quite often when in USIM mode.
Running the card in SIM mode, this doesn't happen.
Cheers
Tom
