My application reads and writes nTAG213 tags and I'm adding password protection to it. I have successfully implement write protection so the app is able to set a password and authenticate for remove it.
However, when I set PWD_AUTH to 1 for read/write protection the tag is protected but, after that, it keeps locked forever: I can't authenticate for removing password protection.
I was wondering if it is possible to retrieve the unlocked status once the tag is read&write protected and, if so, how could I achieve it. Any help will be appreciate it.
Thank you in advance
