Reading Smart Cards with 6212 SDK emulator

[npr.novo]

Are there any known issues related to the 6212 SDK emulator (connected to a Pegoda reader) when reading ISO14443A Smart Cards. A MIDlet running on the phone works fine, but on the emulator I get an IO exception: "Communication error (0x00)".
The target is detected and the "ISO14443Connection" is opened (but the very first exchangeData() method triggers the exception (and only on the emulator).

Any comments will be appreciated?

Thanks!
