Merge Eddystone beacon and DFU buttonless application

Hi, 

I am trying to add the beacon Eddystone features to my DFU buttonless application. 

After compiling the code, I wrote the softdevice, the bootloader and the application in my nRF52832 custom board. However, the application doesn't advertise the Eddystone packets.... :( 

Here is my main.c:
