Problem to process APDU on real external smartcard

[romain_pellerin]

Hello,

we have a tricky problem to solve so now we have to call nokia community for help

We use the Nokia 6131NFC with an external Oberthur Cosmo Dual smart card.

1- We have installed an applet on a card successfully.
2- We can select the applet by process an APDU SELECT command normally.
3- But after that, when we process proprietary instructions the card always responds 9000 (OK) and seems to not process our APDUs with customized instructions.

My questions are:
- Is there a specific class byte to put on APDU in order to reach processAPDU method of the applet? Currently, we have set CLA to 0x00 but we have tested 0x80 too...

- Is there a specific channel to listen on applet to get APDU from mobile phone over NFC? Perhaps with the 2 bits of channel selection, like 0x03 for example?

Our development is an emergency, can someone help us?
Thanks a lot!

Hi,

how did you solve your problem?

More importantly, would you please (or anyone) post some links to documentation on sending APDUs to a Java Card from 6131? i.e. a J2ME Midlet communicating to an external Java Card (sending APDUs and receiving responses over ISO14443 A/B).

Any sample code, examples would be much appreciated.

Many thanks.
