A Project (sample128_After section 5.4) can't go deep sleep?

There is some project like sample128_After section 5.4 that is related to file AN-B-029 Developing a Bluetooth Smart custom profile_V1.0.
I only change some code below to make da14580 go to deep sleep.

/*Sleep modes*/
#undef CFG_EXT_SLEEP
#undef CFG_DEEP_SLEEP

/*Sleep modes*/
#undef CFG_EXT_SLEEP
#define CFG_DEEP_SLEEP

But after that,I can't find any information about the da14580 device on my android app that can be found before changing.
what's wrong and what can I do to make it work?
Besides,the project is has 5 warnings below.I don't know what they means?can you explain?
