We are using CLRC663 plus connected externally with the MCU over UART. Using this CLRC663 plus reader we can detect two nfc type 2 tags simultaneously. Our requirement is to detect 3 nfc type 2 tags simultaneously.
When we are trying to detect 3 tags simultaneously, then we are getting 3 bytes of UID but our UID length is 7 bytes. After debugging more in code, we found that SAK length is coming 2 bytes after cascade level 1 which should be 1 byte only.
We didn't want to use NFC reader library as it is creating a complexity in code for our HOST micro-controller as well as we are facing so many problems while porting the library on our HOST micro-controller. We have developed function routines to detect card and able to detect 2 cards simultaneously.
It would highly appreciated if we could get support to detect 3 multi-cards simultaneously.
