If you are using the driver in non-blocking mode, you will get a callback when the transfer is finished. You can then read the array before setting up a new transfer. Please have a look at the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v14.0.0/uart_example.html?cp=4_0_0_4_5_42">UART example in the SDK</a>.</p><div style="clear:both;"></div>
