RE: About Service and characteristic using method?

Hi Eyup,

If you are new to BLE it might be worth your time to follow along with this Nordic Tutorial. It should clarify the differences between a service and characteristic.

For some more detail I would check out this Intro To BLE. There you will find more information about your question for best practices. I would recommend against using one string because of the extra overhead in parsing it, and that it would take up a lot of your space in the characteristic. Using an int masked for three sections would be more efficient.

I hope the guides are helpful.

Hello,

You have here a good guide to start creating a service: devzone.nordicsemi.com/.../

and if you are looking into the BLE specification you can find that it said :

A service is a collection of data and associated behaviors to accomplish a particular function or feature. [...] A service definition may contain […] mandatory characteristics and optional characteristics.

You can find here some standard services to see some examples if you want to create your own service:
