How to add a 128-bits custom uuid in BLE advertising data?

[Noxstella]

In my project, my master controller need to scan devices through custom uuid.

One problem is that in ble_advertising_init, I can only add 16bits uuid and type of which is BLE_UUID_TYPE_BLE(Bluetooth SIG UUID)

How can I add a BLE_UUID_TYPE_VENDOR_BEGIN uuid and show complete 16 bytes uuid in advertising data?

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,

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?

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

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