I'm trying to read the Session Registers via NFC of the NTAG I2C Plus demo board, but both Read (0x30) and Fast Read (0x3A) return the same data, which I can't understand.
So, for the FAST READ command, I'm sending [0x3A,0xEC,0xED]
I'm looking for the first 8 bytes, but they are coming out as follows:
Byte0 = 7D
Byte1 = 07
Byte2 = F8
Byte3 = 48
Byte4 = 08
Byte5 = 01
Byte6 = 21
Byte7 = 00
These values don't mean anything in the Spec sheet (https://www.nxp.com/docs/en/data-sheet/NT3H2111_2211.pdf )
Can anyone suggest why they're not coming out as expected? Even their default values are nowhere to be seen, but the response is always exactly the same.
