For some reason, the none of the tags work right from the manufacturer. After I write a test message using the app NFC TagWriter by NXP, the tags are formatted and work perfectly with AI2
So you need to reformat the tags first (mine was different than the user you suggested a MIFARE classic). Once you reformat the tag, you can write/read from the NFC tagwriter by NXP app.
Then the cup program and our test programs are working.
This information should be added to the tutorial. There's no hardware information other than buy tags that are compatible, and that information is insufficient especially based on others who are having the similar issues.
