Push Notifications or Intents to Phone from BLE Device when App is turned off

Question

I have an BLE smart device that at any time should be able to inform the android cellphone of it's current state.

If I previously bounded the BLE device to my phone with my application but I have the app turned off . Can I then send an intent or notification to the phone from the BLE device to open the app or inform the user that something happened?

I also need to make the same functionality for IOS later on.

Answer 1

You can write a background Service class which scans for BLE devices. When app comes in device proximity, you can send a notification to the user. Remember,your device bluetooth should be turned on always.
