Hello,
I'm currently working on an application with Mifare DESFire EV1 AES Authentication and I used SLOA213 with the DLP-7970ABP BoosterPack as starting point. I'm wondering why anticollison and selection is working with higher distances than the AES-Authentication?
Or in in SLOA213 code: Iso14443aLayer4() is returning STATUS_SUCCESS on distances <=20mm but Aes_authenticate(...) only receives valid data on distances <=5mm. What's the reason for this? What am I missing?
Thanks and best regards,
Oliver
