Configure UART with HAL_UART_Init() with some baudrate 'X' 

Start receiving with HAL_UART_Receive_IT(Size = 1) 

Send any frame with baudrate different than 'X'

catch HAL_UART_

RxCpltCallback() followed by HAL_UART_ErrorCallback()

Shall I receive 

HAL_UART_

RxCpltCallback()

 or

 HAL_UART_ErrorCallback() but not both on each HAL_UART_Receive_IT() call?

tested with STM32F103RF
