How to receive information from Android NFC enabled device using MFRC630?

iwanders commented 1 year ago

@chcmq , good question, I have no idea if that's even possible. You'll want to read up on how nfc actually works, if the frequency / hardware protocol is even supported by this chip. You probably can't use any of the ISO14443A related functionality.

In short; I have no idea, do report whether you got it to work or not. I'll leave the issue open in the hope that others chime in!

Can it be used to read and write NDEF messages

peturdainn commented 1 year ago

NDEF is just how the data is organised in the tag memory

chcmq commented 1 year ago

NDEF 就是数据在标签内存中的组织方式

Is there any relevant case? I need to use the MFRC630 library to receive the NDEF data sent by the mobile phone's nfc, but I don't know how to implement it, please

AFAIK this library is written for the 'master' use case where you communicate with a tag, not a 'slave' use case where another host communicates with you. Not saying it is impossible, but you will need to write the top logic yourself. Also there is no NDEF parser here, though that is not so difficult, the spec is pretty straightforward.
