i am adding dfu feature to ble_uart code.

i did all steps as explained in https://devzone.nordicsemi.com/f/nordic-q-a/48872/how-to-merge-one-application-with-dfu-feature.

my code is compiled properly.when i program it in nrf52dk it does not advertise anything.

Hi Harry, 

When something doesn't work as it should, please try to debug. First, check the log, second try to debug and step into the code to see if there is any assertion. 
We can't help if you simply just say "it does not advertise anything"
