UART never in ready state for transmit function

I am trying to include UART into a sample program without using cubeMX. To my knowledge I have added everything it needs, but when I get to the transmit command, it checks the statement:

huart->gState == HAL_UART_STATE_READY

which is always false. It then goes into the else part of the execution, which returns that HAL is busy. What must I include for it to be in the ready state?

Rather than play these guess what's wrong games, show the code and it might be more apparent.

Make sure not to miss MSP code, or IRQ handlers
