How to modify the BLE gatt server profile

Question

I need to create a ble custom profile for my peripheral server in Linux and C code. I tried to modify existing time profile under /bluez_source_code/profiles/time folder. I have modified

UUID number (added custom UUID number in the uuid16_table in the UUID.h) and name
Added new characteristic

I have compiled the whole ble stack and tested the time profile. The peripheral client sees the no change the UUID number and charateristic name.

Is there any any thing else I need to modify for the custom profile.

As M. Kotzjan mentioned, I wouldn't modify an existing adopted profile because this can have issues. Instead I would create a new gatt server/peripheral device from scratch. If you want an example to do this from the command line, have a look at the link below:-

and if you want code to create a peripheral using the D-Bus API, have a look at the links below:-
