Hook up TX on one MCU to RX on the other, and vice-versa. Use HAL_UART_Transmit/HAL_UART_Receive to send. Should be examples in the CubeMX repository.

hello sir , thank you

i am trying to link stm32 to other unit board already programmed when i enter for exemple a référence as input ( F01 98 7 /r) i expect in return to receive " OK " after the test

this can be done using docklight , but i need to know if there is a way to program stm32 with C language

If you're new, there should be a lot of videos on STM32CubeIDE to get started.

But if your goal is just to send data over UART and receive data back, a USB to UART adapter seems like a faster/easier/better choice.
