Hi all,

Mmm, although they are similar at the higer levels, T=0 and T=1 are pretty different at the 'byte' level and I'm pretty sure you'll need to adapt both the firmware and the host app (since it tries to interpret the bytes to fw entire APDU to wireshark).
Yes, this is true. I think I remember having started to work on T=1 support at some point in the past, but I cannot find the code anywhere. Maybe it was just an idea, after all.
The hardware can definietly do it. One of the reasons it is not implemented in firmware / host software yet is simple: All SIM cards are mandated to also support T=0, and I don't think I've ever seen a phone that actually uses T=1. So there are many other tasks higher up on the priority list than the mostly "scientific" interest in T=1 support, sorry.
