Implementing DFU OTA for beacon

Question

Hi Nordic, 
 I am trying to extend DFU feature to my beacon application. Please help me with how to go about it. I went through the given tutorials on DFU/OTA, but I haven't got a clear idea on how to implement it for beacon. 
 Also I have a doubt.. 
 Is DFU code snippet alone, enough for the beacon application, or is it to necessary to add the device manager snippets too, as given in of the peripheral examples?

I did a quick test, seems to be working without Device Manager. I just skipped calling dfu_app_dm_appl_instance_set() after removing Device Manager. 
 Here is my main.c , can be used with the ble_app_hrs dfu example. 
 The first step is to see add the DFU service and get it to appear in nRF Connect. 
 You need a trigger. You need a way to tell the application that it should go into bootloader mode. This is typically done by a button, or you can go buttonless by using DFU service. The DFU service can only be accessed in a connection. 
 You can implement buttonless DFU in a beacon application, but then it must be connectable. A beacon is typically not connectable, only advertises.
