How to generate different UUID's for service and characteristics

[Swapnil]

Hello,

I want to generate different UUID for service and for characteristics with different base address for both.

I am updating base address in characteristics_add function and uses this function: err_code = sd_ble_uuid_vs_add(&base_uuid, &char_uuid.type); before, sd_ble_gatts_characteristic_add();

But still I am getting the base address of service only not the upadated characteristics base address.

I am not getting what would be the problem

You say it "crashes", do you mean that you get an error code? Have you checked what the error code is using debugging? I checked your code (incorporated the relevant lines into one of the SDK examples, as I don't have your complete application), and I got two separate base UUIDs showing in nRF Connect.
