BLE custom UUID

[Jitendra]

Hello Everyone,

I have a basic question related to custom BLE service 128-bit UUID.

I know the custom ble service base UUID is the "00000000-0000-1000-8000-00805F9B34FB". and we can use any 16 bit or 32 bit UUID to converted 128-bit UUID by changing the first 4 bytes of the base UUID. My question is can we create below kind of custom ble services:

be3942ad-485c-4fce-9bce-110c2ec28897

329cbe43-6540-4a04-a9f7-41616c3b9f61

c681d71d-91dd-4c96-b486-0e0d2ae452a9

2b357f98-7a1e-4b5b-8e6f-6daa11adfbf7

2e2da474-8be1-4c39-aeec-18f4e0717eb9

If yes, then what is the base UUID and how to create it?

If not the why we can not create, what is the restriction?

Any help will be appreciated.

Thanks,

Jitendra
