Great, I switched to transmission in DMA mode which finally allows me to keep the high baud rate and non-blocking call of DIAGN_Print().Thanks for explanation!

Thanks TDK, this was a super fast solution! I wasn't aware of the fact that HAL_UART_IRQHandler gets called after every character transmission as well, I was erroneously supposing it only gets called once at the end of packet transmission.HAL_UART_I...

Thanks for your reply. I have already seen the syntax of __HAL_UART_ENABLE_IT and totally agree that there is no logic for this to block. However, let me give more details.Main loop:while (1) { DIAGN_Print("ABCDEFGHIJKLM\n"); HAL_GPIO_ToggleP...
