Send event to iOS in background mode

[Robert]

I'm lost. Can someone point me to place or the best example of how to send data (any) from NRF51882 to iOS app when app is in background. Is it possible at all ?

Hi,

I think it don't base on nRF51825, it base on your iOS app.

So, you should check this link to understand. stackoverflow.com/.../ios-bluetooth-background-mode

My question is more trivial. Which service should I use inside NRF to notify iOS about changes in device (button pushed).

Hi Robert,

You should use notification to send data from the nRF to iOS.

To read more about notification, please follow this tutorial. The tutorial used the MCP application on PC as central device, but it's similar with the nRF MCP app on iOS and nRFToolbox app that you can find the source code on our GitHub.
