my main issue for now, is managing to handle Ultralight EV1 tag. for that we are used to send raw APDU. I have tried, to use the nfc.transmit method, but I suppose it needs to receive more than just the basic apdu code, and it's more low level than I expect. Basically I'm used to transceive : 0x60 -> GET_VERSION 0x1B... -> PWD_AUTH 0x30... -> FAST_READ ... But here passing those value give me errors. I had no issue using the m1_authenticate m1_read_block m1_write_block If you have some sample code, managing to read/write or send the GET_VERSION apdu to an ultralight code, it should be enough for me to take after.

Hello team, I was able to check the demo for the NFC Mifare classic. The problem with the demo is you need to press a button to open the nfc, then you need to press another to authenticate and finally press another to read. With our app we need to be able to do all this steps without user interaction. Apart from that we need the app to be listening all the time for an incoming nfc tag. That’s why I was asking you last time if there’s something like a listener similar to the one you have with the QR Reader (setHardReaderListener). I would really appreciate if you can help me with this. Thank you.
