Dear Nordic Team,

Now i am trying to work DFU with NUS example.I am following As per nordic document like: infocenter.nordicsemi.com/index.jsp

Hi Murugan,

First please test just the DFU bootloader and the unmodified ble_app_hrs and let me know if you can update and if the application run. Then try to jump to bootloader (holding a button for example) and update again same application. After that test with your application (no DFU service integrated) make sure DFU OTA works with your application.

Only after that, you can try to integrate the buttonless DFU service into your application and test.

Have you tried the buttonless example that integrated in the ble_app_hrs ? What exactly the problem, have you tried to debug. And please try to test your application with no button less DFU. Try to switch to bootloader using a button and update (and re-update) your application.
