You should check out the developer documentation for whatever mobile OS you are using? The BLE profiles aren't specific to particular hardware, and as I said it is the OS on the phone that handles indications/notifications on that side. iOS does have a service for this and can be found in the Apple Notification Center Service documentation on our Infocenter.

Case 1 & 2: In the central that is receiving notifications (whether it is an nRF chip or a phone), you will need a service client/handler that is able to handle the notifications from the peripherals notification service.
Yes, you will need the according service handler on the client side to match the service that the server is providing.
Yes, I think you should be able to start out with the battery service in order to create a notification service updating the phone every second or so.

Thank you for the response.Please can you make me clear on below points.

Case1:If I want to send some notification/data from mobile to nRF52832 then Should I have to create service on nRF52832?Case2:If I choose to send notification/data from nRF52832 to mobile then Should I have to create service on mobile?

If I am considering nRF52832 as server and mobile as client,while implementing services as in Case1 I have to create service using gatts structure as it is been created on server side and while implementing services as in case2 I have to create service using gattc structure as it is been created on client side.Am I right?

In Alert Notification example,service is implemented on client side upon button press we are able to set cccd values on application.

After I have posted question,I went on looking into exsisting examples looking for the service that is updating the value of characteristics.Then I found Battery service where it is updating the characteristic value every 1sec.I found it suiting my application.Am I right ?can I implement notification service using battery service concept.

Thanks & Regards,

Hi Swathi

Please check out the Alert Notification Application example project in our SDK. It connects and alerts an application about an incoming call using buttons on the DK, and it is able to print text strings. Keep in mind that it is the operating system on the phone and not the app itself that handles notifications and indications.

Best regards,
