hi,

i have STM32F401 with uart1 configurate in DMA and i would like to add uart2 (in DMA or not)

is it possible to do it?

how i manage the IT flag?

UART1 DMA, call fct :

void HAL_UART_TxCpltCallback(UART_HandleTypeDef *UartHandleArg)
{
  WiFi_HAL_UART_TxCpltCallback(UartHandleArg);
}

but when interrupt is uart2, how i do?
