yes you can if you use the iso15693 protocol in coreNFC. If you use the NDEF protocol, Tag must be NDEF formatted with at least an empty NDEF message.

issue is fixed in iOS15 beta2 release. Wait and see next iOS14 official release ....

Hi , I agree with Micke_S : The M24LR16E (and M24LR64E) requires 2 bytes to code the block address in the Read Single block command, which is not standard. So, I don't think that coreNFC will implement this as it follows the standard. Moving to ST25DV16 is the solution.

hi , No, this is not yet possible with coreNFC to emulate iphone as a NFC Tag. The HostCardEmulation mode is ONLY reserved for Wallet applications (ApplePay, CarKey, ...) and is not accessible at user level. good luck.
