Hello everybody, I just got into STM32 development and using the HAL library primarily for my developments now. I am having a issue with UART IT library function. Why when I have a for loop delay or HAL_Delay in my main code the Buffer data is not updated, I keep receiving the first byte consecutively, it worked very well if I don't have delays in my code.

main raw code :

Keil MDK project :

Or if you want to clone the repo :
