Creating custom bluetooth service/charasteristic
Hello. I have ordered stm32wb development board and recently started to learn about the Bluetooth. I am planning to control an electric lock through bluetooth mobile app.
I have seen the stm32wb workshop, especially part 4 where they are creating a custom template:

I would like some general advice regarding making my first Bluetooth program. Can someone advice me regarding what service and charasteristic I should be using? Should I use a random UUID or should i pick one that is predefined?
If I use custom UUID, on the phone BLE application it is going to show up as unkown service right? If I want to make that service known, I would have to create my custom Bluetooth application and use the same UUID?
