Hello everyone.
I have a problem with the RC522 tag authentication need your help.
At first, i read its id successfully. Then Authenticating to write 10bytes "1010101012" to block 10 OK also.
But after that, I can not read / write from/to this block and all the others also (but always got the id).
It says the authentication is failed, even i use the:
default key (0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF),
madKey ( 0xA0, 0xA1, 0xA2, 0xA3, 0xA4, 0xA5 )
and NDEFKey ( 0xD3, 0xF7, 0xD3, 0xF7, 0xD3, 0xF7).
Plus, I used authentication key A.
Please help me to solve this, thank you very much.
