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.

I was testing our app with the T20. The NFC and QR reader did not work with our app. Are this functionalities native to the device or they work with an SDK? Thank you
