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 ?

Is this Nordic example or yours? I have faced same behavior few months ago and i saw that i have to initialize services first before advertising_init(). I didn't ask anyone then, but i believe it had to do something that i was putting my own custom service UUID in the advertisement packet. So i was trying to put that service UUID in the advertising packet, but the service wasn't initialized yet. So calling services_init(), before advertising_init() fixed that. Then you don't have this problem in Nordic examples, because they are using services which are defined by Bluetooth SIG and their UUIDs are known before initializing those services. Could be great if someone could confirm that my speculations here are correct.
