@sandeepmistry Currently trying to get your repo working with a Raspberry Pi Zero W connecting to an iPhone 6 Plus on iOS 10.3.1. After pairing the device using the GUI, I am unable to get test.js or any other implementation working correctly. I can see the messages discovered, connected, and services and characteristics discovered; but then I never see any further messages. No notifications show up but the iPhone says it is connected to the Pi. Any suggestions/help?
