Sorry the exact function is sd_ble_uuid_vs_add and sd_ble_gatts_service_add is used for adding ble service

sd_ble_gatts_service_add ? But how can I show my custom complete uuids in advertising data?

Yes there is an SD function call to add custom UUID values.

Thanks Simon

Neither of the macros can be found in nRF5 SDK and we are not going to move to nRF Connect SDK for some reasons.

Are there some other ways to add a 128-bits custom uuid other than uuids defined by SIG on the nRF5 SDK?

o add a 128-bit custom UUID in BLE advertising data, you can use the BT_DATA_BYTES macro with the BT_DATA_UUID128_ALL type. There are multiple samples in the nRF Connect SDK showing how you can do this. The Bluetooth: Throughput sample would be a good starting point. I see you're currently on the nRF5 SDK, but would strongly suggest you move to the nRF Connect SDK instead. See the statement on the SDK statuses available here for more info: nRF Connect SDK and nRF5 SDK statement

Best regards,
