Dear,
The DVK90121 allows you communicate with a transponder using basic ISO commands (ISO15693 and ISO14443). The NFC protocol at 212kbit/s as presented in the corresponding application note is not supported by the development kit. For that, you will need to write the firmware by yourself.

Please note that only the NFC at 212kbit/s (Felica protocol) is supported by the MLX90121. The others modes (106kbit/s, 424kbit/s and 848kbit/s) will not be able to implemented with this device.

Best regards

Dear Denis,

The NFC file transfer described in the application note was actually the reason I purchased 2 development kits. Is there a possibility to obtain the code so I can at least repeat the experiment described in the application note ? Unsupported code should be fine since I don't need to tweak data rates, protocol etc...

Thank you very much. Kind regards,

KVS

Dear,

The pear to pear communication at 212kbps with the MLX90121 is not supported anymore. Our new device MLX90131 (available end of 2008) will support the NFC communications up to 424kbps.

Best regards
Denis
