Android NFC RF Time

I work on Android 2.3.3 with Nexus S. I try to read smart cards ISO14443 B type.

I can read and/or write on the cards without any problem. But I am using a card which doesn't respect the ISO timing. When you use the ISO cards, the timing is nearly 5 or 7ms but I need to increase this timing.

I need of your help at this point. How can I increase the timing? I don't know开发者_运维问答 how to do it at the low level.

Do you have any solution?

Thank you for your help.

The nfc.technology IsoDep has a function to extend the default time-out value.
