You need populate it with the correct version numbers when you initialize it, for example getting application and bootloader version from the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/lib_bootloader.html?cp=4_0_0_3_5_0_0#lib_bootloader_settings_page">bootoader settings</a>&nbsp;in flash (<a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/structnrf__dfu__settings__t.html?cp=4_0_0_6_11_7_0_8_2">nrf_dfu_settings_t</a>). There is no standardized field for bootloader version, but you could perhaps use the FW revision for bootloader and SW revision for application.</p><div style="clear:both;"></div>
