So I'm using Keil v5.18.0.0, MDK-Lite Version 5.18, nRF Beacon app version 1.4.2, android 5.1.1, nRF51822, and nRF52832 micro-controller I can successfully connect te bluetooth beacon with the app on my phone to open the mona lisa picture, open a web page, etc. but I want to send a custom notification to my phone whether it be to the app or not. Is there a way i can send a custom notification to the beacon app or to a different app i can get from the play store? I want to have the controller tell the beacon to send a custom notification to the phone.
