I bought 100 pieces of RFID reader from a vendor for cheap. Now I got to know it is not compatible with our code which works fine with RFID readers with firmware Version: 0x92 =v2.0.
The RFID reader I bought have firmware version 0x12=(unknown).
How can I update the firmware of my RFID card reader ? If it is possible then how can I do it ? what tools and software will I need to update the firmware on these RFID reader. Please guide me NXP community.
