I am using NXP om5577 device on raspbery pi board (win10 iot), mifire plus se card, C#.
I am stuck with switching security level SL1 -> SL3. Sending apdu command FF C2 00 02 04 8F 02 00 04 (set to ISO 14443-4 Type A, communication layer 4) returns 6F00 - internal exception. On ACS ACR1281 1S Dual Reader PICC 0 this cmd works fine.
What could be wrong?
Switching from SL0 to SL1 works fine.
