How receive ATR from Smartcard correctly?

[SMac]

i want to get ATR from Smartcard using stm32 Nucleo F429ZI. 

Well, using oscilloscope i see signal from CLK, RST and I/O (so i proved that i connected Smartcard and STM correctly). But in my code (i use STM32CudeIDE version 1.0.2) i can't see ATR in my array. Where have i make a mistake?

I am a total newbie in STM32 programming so i need advice. Here's some code in file stm32_main.c.
