Present sector password on M24LR64E-R with ios14

Hello,

Im trying to read data from a M24LR64E-R tag with password.

So, Im using customCommand() function with these data :

  • flag : 0x0a
  • command : 0xB3
  • payload : bytes from password

This command works on Android but on ios I receive this error :

[CoreNFC] 00000002 83601300 -[NFCTagReaderSession transceive:tagUpdate:error:]:710 Error Domain=NFCError Code=100 "Tag connection lost" UserInfo={NSLocalizedDescription=Tag connection lost}

It's the same with readSingleBlock command but I received the same error.

Do you have an idea ?

Hi ,

I know that some flags parameters does not work in iOS CoreNFC (ex : addressed mode Flag). Issue was raised to apple, but no answer yet.

In your case, you use the protocol extension and two sub carrier (flags = 0x09). Please, could you try again with other values ? for ex : Flags = 0x02 ?

Could you send me your complete code sample as well ?

hope it helps. Let me know.

Thx and br,
