Hi all,

I'm trying to test smartcard library for stm32f102, i have a problem

I received a A2R, then i transmitted a byte from MCU to card, i received it from card. But when i transmitted continuously than one byte, i only received the first byte. Can anyone help me ?

I use ST8024 between MCU and smartcard.

Presumably to handle the ESD, power supply, and short circuit protection on the pins.

It's not that you can't connect it directly and have it work in most cases, it's the cases of defective, damaged or wrongly installed cards. Can you afford to deal with MCU's that get blown out in the field?
