First byte of Random UID

dharmikm91 — Mon, 01 Mar 2021 19:46:54 GMT

Hello, I am trying to authenticate a DESfire card using the Pegoda. For my application, I need it to use the Random UID and not the card UID. According to the documentation in MF3ICD81 (Product Data Sheet) and AN10927, if we set the card to use Random UID using 'SetConfiguration' command, it will assign the first byte as 0x08. However, when I am trying to get the Random UID on my Pegoda, the first byte of the 4-Byte Random UID is 0x80 which is causing my tests to fail.

Can you please help me out?

Thanks in advance.
