For this explanation please follow attached image. It explains the communication loop for selecting an NFC card.
I am trying to read the 7-bye UID from a Mifare Classic 1k card. So far, I have managed to read the cascade tag (0x88) and first 3-bytes of the UID. I have also received the first SAK response (0x04) from the card.
However, when sending the SEL2 (0x95) and NVB (0x20) bytes I am not receiving a response from the card. Hence, my card reader (MFRC500) is stuck in receive.
Any suggestions or tips on what to check to find the issue?
Thank you in advance.
