If you're using SDK v12.x.x or newer then you need to send the firmware over the UART according to the documentation found <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v13.1.0/lib_dfu_transport_serial.html">here</a>. If you're using SDK v11.0.0 or older then you need to send the firmware according to the documentation found <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v11.0.0/bledfu_transport_serial.html?cp=4_0_5_4_3_1_4_2">here</a>.</p><div style="clear:both;"></div>
