for what neded init.advdata.uuids_complete.p_uuids in a static void advertising_init(void) function?

[Mikhail]

I use SDK15, nrf52832, s132

When in the 

static void advertising_init(void)

I comment 

    init.advdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
    init.advdata.uuids_complete.p_uuids  = m_adv_uuids;

two lines.

Seems works. I can observe on an android nrf connect my device. But on a IOS can't see it via standart settings.

If I add those ... uuids_complete... lines- my devise appear on the IOS.

Why?

But why nrf connect on the android sees device wo thise two lines ....uuids_complete....

This might happens because the device caches information about the advertisement packet, and uses the same data. Try to disable/enable BLE or reboot your phone, on the android, and check if the service UUID disappears. See this link to read more about caching.
