Problem with NTAG protected in NFC side

Hello,

I am using the NXP tag NTP5332 and actually I has problems with commands that are sent via NFC using customized mobile app. On the NFC side, I am having problems writing to a password-protected memory region. To read a memory region protected against reading, I follow the sequence of commands described above, changing only the Password Identifier to 0x01 and the operation to read; in this case, the read operation is successful. If the password protection against reading and writing is removed, the read and write commands work without any problems.

Can anyone help me with these issues? Am I sending the wrong command?
Thanks for your help!
