I'm sending a simple string to with HAL_UART_Transmit() "Hello", and when I look at the Input on my COM-Port there is nothing showing up, just a blank plain text site. Yes I am transmitting at the right baud rate 115200 and I don't have an extra parity bit or anything of that nature. I'm using default settings on everything here. My Board is a NUCLEO-H563ZI with an STM32H563ZIT6. I am using UART 7 to communicate. I will also link my files here. I have basically tried every UARTx and USARTx. When I check the State with HAL_UART_GetState() I get HAL_UART_STATE_READY and as return on the HAL_UART_Transmit() I get HAL_OK.
Solved! Go to Solution.

Apparently, this wasn't the solution but maybe it was in the right direction, because as I said I have no idea how my board and my computer do the flow control...

I just had to use USART3 (PD8/PD9) and it totally worked. I think it didn't have anything to do with the flow control.
