Currently this is SDK 11 and S130 v 2.0.0. The <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v11.0.0/examples_ble_dfu.html?cp=4_0_0_4_3_1">DFU documentation</a> is extensive and has a separate section on how to set up the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v11.0.0/bledfu_appextending.html?cp=4_0_0_4_3_1_2_1_2#bledfu_ble_services">DFU Service</a>.</p> <p>If the problem is to add another service you may find it usefull to brows through some of the examples, and also the <a href="https://devzone.nordicsemi.com/tutorials/8/">BLE Services, a beginner&#39;s tutorial</a> and the <a href="https://devzone.nordicsemi.com/tutorials/17/">BLE Characteristics, a beginner&#39;s tutorial</a>.
