Hey guys,

this problem has been around for ages (from my perspective) .. and I don't
seem to understand if it's a SW issue or a HW issue.

I start the ./simtrace .. and then insert the SIM into the phone (or vice
versa), boot up the phone and start sniffing (log below).

It works for a second or two and then the stuff get broken into weird parts
.. I could probably fix that in apdu_split.c

but the other issue is that it stops sniffing completely at that point for
some reason.

Any idea why that happens?

Thanks!

Lukas
