Alert Notification Service with need for sending string from Central to peripheral(nRF52 DK)

[Nousher Najeeb]

I am new to ble,
I have to develop an alert notification service on nrf52 DK . Some times i need to send strings from the central to the peripheral Is there any way to achieve this using Alert Notification Service, if so which characteristics should i use? OR should i use multiple services for this?

Does Nordic UART service is suitable for my application? Is it power efficient ?

Hi

Yes, I think the Nordic UART service is a good fit for your application if all you need to do is to send strings back and forth. 

There is no reason you can't implement a power efficient application using the UART service. In the end it depends on your connection parameters, how much data you are sending, and what else you are doing in your application.
