Hi!
I can succesful read UID from Mifare Classic uand DESFire EV1 with/without Collision.
If 2 PICCs in the field first I read the UID from PICC#1 then PICC#1 should go into HALT, and after this I'd like to read UID from PICC#2.
After reading UID PICC#1, finished with SAK, then >3ms later I send HLTA to stop PICC#1:
0x8F 0x01 0x08 0x91 0x3D 0x00 0x20 0x50 0x00
Then I get after a REQA 0x50 (CRC ERROR) in the IRQ-status Register but no ATQA.
The PICC doesn't go tinto HALT mode.
I get same result in the IRQ-status Register even if only 1 PICC is in the field.
What's wrong?
Thanks
Robert
