About disconnect alert app when device disconnected

[Jones]

Hi,

We are developing a  device which connect to a smart phone and alert the user through smartphone when the device disconnected (out-of-range).

So I guess this app should be run in background and trigger the app to wake up/ open the app when disconnected.

Is any example or resources (android) I can refer to ?

Thanks,

Jones

That would be a question for an Android developer forum.

It wouldn't be specific to Nordic.

i just wonder if nordic already developed related sample app which could let me refer to.

Hi Jones, 

The proximity example in our nRFToolbox app should do something similar. It trigger an alert on the phone when the device is disconnected. 
The peer (nrf52) should run the ble_app_proximity firmware.
