Hello,
there is some solution for sending data over multiple uarts with RTOS,
because HAL_UART_Transmit,HAL_UART_Transmit_IT,HAL_UART_Transmit_DMA not send data in second uart. Still BUSY.
Thank you in advantages

If it returns HAL_BUSY, the peripheral is still servicing the previous call. You will need to wait or implement a buffer to hold data until the peripheral is ready to send it out again.
