Is there the turn of Advertise and Service initalize ?

[mino]

I tried to work application. But firmware stops at advertising_init(). When I exchange advertising_init() and services_init(), firmware does not stop. why ?

SDK v8.1.0

No the firmware doesn't stop, it's somewhere doing something. What are the two values of err_code before the APP_ERROR_CHECK()s? If they aren't zero, then one or other of them failed with an error code telling you why.

so you are encoding 16 bit UUID, but your uuid=0x20003B14? Thats 32-bit. error code itself 0x00000007 stands for NRF_ERROR_INVALID_PARAM, means you passed invalid parameter to the function.
