Hi,
T=0 and T=1 are quite similar, and I don't know if
any adjustment is required on the firmware.
Maybe the firmware only needs to tell the micro-controller to switch to T=1, and then it
works flawlessly.
Harald Welte would be able to answer this question in more details, but he is not online
before next week.
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).
Cheers,
Sylvain
