shoould I change gatt uuid in production application

[frankiPL]

Hi all

This question is related to gatt_server.
Should I change uuid in production application? I have one service and 4 characteristics, I was using demo gatt_server_service_table
Now I have uuids:
service - 0000180d-0000-1000-8000-00805f9b34fb
characteristic - 0000ff01-0000-1000-8000-00805f9b34fb
characteristic - 0000ff02-0000-1000-8000-00805f9b34fb
characteristic - 0000ff03-0000-1000-8000-00805f9b34fb
characteristic - 0000ff04-0000-1000-8000-00805f9b34fb
notification (CCC) - 00002902-0000-1000-8000-00805f9b34fb

My app is not related to Heart Measurement and I don't have registered uuids. Should I change whole uuid, I mean
0000-1000-8000-00805f9b34fb
or just service uuid 0000180d ?

Best,
Marek
