Declaring a service structure in your application

[MichaelNordicUser]

Hi,

I am trying to develop the ble_app_template project into a custom ble application.

Where is says

/* YOUR_JOB: Declare all services structure you application is using
   static ble_xx_service_t          m_xxxs;
   static ble_yy_service_t          m_yys;
*/

What am I supposed to do? Am I supposed to create data structs with members representing properties of the service? Is there an example somewhere?

Thanks

Depends if you app needs to have a service, its perfectly possible to have an app which just advertises data but is not connectable..

But if your app will have a connectable service (or services), the normal advice is to not start from the blank template if you are a beginner, but start by copying the exmple which is most similar to your product requirements

If you are developing a custom service, the best example to use is the ble_app_uart as this uses the NUS service which is a custom service in the first place.

Then just duplicate the NUS Service to make your own service and update the nble_app_uart template to use your own custom service(s)

I don't wan to use the UART service. I want to create a custom service from a basic template. Can you please provide an example of a service structure declaration?

[Roger Clark]

Even if you don't want to use the UART service, it contains an "example" of how to write the service structure stuff, and the NUS is a good example of a simple service

HI Michael,

you can take a look at this tutorial, it shows you how to create a custom service with one characteristic, using the ble_app_template example in the SDK.

Best regards
