Dear All,
So what about sending ADPU to the SIM card ? We are currenlty integrating a NFC device on a G1 and we need to send APDU comands to the SIM to take advantage if this. What is the best way to do so ? BTW: Who know what is the modem used in ADP1 ? Getting this information would allow us to learn more about the specifics of the AT interpreter. Bst rgds.
