I want to read/write AS3953 (NFC chip) through SPI (MSP430) and PCD (Samsung Galaxy S3 Mini).
No problem for the first part (through MSP430 SPI). but when I want to read EEPROM values trough PCD, I have just a "bip" from my smartphone and the applications I use(NFC tag info, Nfc reader, ....) cannot read the tag.
The same behaviour with the constructor demokit.
Am I missing something to perform PCD-EEPROM read write ? Datasheet
