nrf52 S132 serialization 128bit advertising issue

The base UUID for the 128-bit UUID is added to the SoftDevice inside services_init(). This base is not available if you call advertising_init() first.

Found out the issue. I ported most of the code to HRS_SER from APP_UART. The HRS_SER initialized advertising_init before services_init but app_uart does the opposite with services_init called after advertising_init. Looks like for 128-bit UUIDs you need to initialize services before doing advertising_init but not for 2 byte UUIDs. My suggestion would be to make the examples consistent with the order of initialization :) Also, I was able to use both uuids_complete and scanrsp_uuids. I just shorterned the name for Nordic_UART since doesn't fit in 31 bytes with 16 bytes uuid. Thanks for you help!

I just tried adding the the NUS 128-bit UUID to ble_app_hrs_ser, using serialization over UART. Seems to be working fine, had to use a scan response though. I tested with SDK 11 and S132 v2. Maybe you could uplaod your application so I can test it here? What serialization did you use? What SDK and SoftDevice version?
