Therefore, the SDK also cannot support multiple concurrent USARTs.</p> <p>You could probably implement a software based USART if you really need two USARTs on your project.</p> <p>Or, if you know you won&#39;t be using both concurrently, you could software select which IO pins the hardware is connected to at any given time.</p> <p>I highly encourage you too look at the source code for the app_uart_init() and related functions. They&#39;re very basic wrappers around the hardware control registers if memory serves.</p><div style="clear:both;"></div>
