I am very new to these programmings, so my questions will be amature forgive me for that.
How to use  HAL_UART_Transmit/Receive _ Polling in my program multiple times.

my users will send data multiple times to the micro controller(STM32F7) through my UART, so whenever I receive , it need to be checked and reply back i.e transmit some data back to the users.

Waiting for your reply guys
