I use BCard professional 5.4H with ATMEL library.

If I want to get back generated privatekey I got empty string with ATMEL, and I got "real" value 21 byte long string with PC terminal test fro card.

The BCard procedure is very simple.
Command &H20 &H06 GetPrivateKey (PrivateKey$)
PrivateKey$ = EC167PrivateKey
End Command

Why empty EC167privateKey on ATMEL, and why does it contain data with SAME card in PC teszt?
