Recieve Notification

[Inspectron]

I have an android application, which one can set and unset the LEDs of my nRF51422 EK. But sometimes when I click to fast the command will not be send. So I would like to get a notification if the Chip recievs the command. Is there an example where I can see how I should do that? I hope I can handle the notification with the same service as I set the LEDs.

Then you have to set the characteristic as an indication instead of notification. An indication will reflect an ACK all the way up to the application.

Please have a look at for example this case.
