Hi again.
So after some digging I'm quite sure the ADPU response doesn't make it back into the upper layers. My question is , case the osmocon output contains some weird characters (see bellow), I should assume that at that point something went wrong with the serial link? Also is there some flag to compile the firmware such that the prints have no effect, as to offload the serial link?
Thanks,
Mihai.

No not really ...

But there is a good reason the SIM driver is not in master ... it
sucks at several level, including blocking behavior in interrupt
context IIRC, so it's totally plausible your machine speed triggers
some weird things.

My advice would be to:
 - Cleanup the SIM driver
 - Bypass it in the code and try to access a real PCSC device locally
rather than the built in SIM reader.

Both are non-trivial of course.


Cheers,
