[quote user="Sudhir Foujadar"]Can you let me know how does the ble stack work , in terms of which function are called and its respective events. I am confused why are multiple events triggered or needs to register.&amp;nbsp;[/quote]
&lt;p&gt;Not sure how much you know about the BLE. I would suggest you take a look at our &lt;a href="https://devzone.nordicsemi.com/nordic/short-range-guides/b/bluetooth-low-energy"&gt;Bluetooth low energy tutorials&lt;/a&gt;.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;If you have further questions regarding the&amp;nbsp;&lt;span&gt;ble stack, please create a new support case. This is away from the original scope.&amp;nbsp;&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;After downloading the memory map in right is shown by reading it&lt;/p&gt;

&lt;p&gt;What is the SDK version you are using?&lt;/p&gt;
&lt;p&gt;What is the phone OS, Android, or iOS?&amp;nbsp;&lt;/p&gt;
[quote user=""]8. Mobile app shows following Starting DFU and then the graph is blank noting data is sent and after somtime DFU test is diconnected.[/quote]
&lt;p&gt;Are you able to provide the log of&amp;nbsp;the&amp;nbsp;&lt;span&gt;nRF Connect mobile app after you run into the issue?&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;You could double-check the&amp;nbsp;hrs_application_s140 is from the same SDK version/folder as the sd_s140_bootloader_buttonless_with_setting_page_dfu_secure_ble_debug_without_bonds.hex.&amp;nbsp;&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Due to the holidays here in Norway we are short-staffed,&lt;span&gt;&amp;nbsp;&lt;/span&gt;so&lt;span&gt;&amp;nbsp;&lt;/span&gt;there will be some delay in your answer.&lt;/p&gt;
&lt;p&gt;You can expect an initial answer on Tuesday.&lt;/p&gt;
&lt;p&gt;Best regards,&lt;br /&gt;Heidi&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
