uart data mismatch

[TejasK]

I am using stm32f407 and stm32wb series for sending the data usimg uart.
first i send th data using the stm32wb uart to the stm32f407 uart the data is correctly sent.

After receiving the data i will return the data back to the stm32wb from the stm32f407 but this time the data is corrupted.

I am using the hal_uart_receiveto_idle and hal_uart_transmit_it to send and receive the data. 

I will share the code please review and tell me if i need to make any changes.

You really need to do that!

Otherwise, there's no way to tell if the problem is in the receiver, or the transmitter - or both!
