Push notifications requires to be pushed from Apple's or Google's notifications infrastructures.

For iOS there's local notifications that your app can trigger based on your conditions, but from my knowledge when the Bluetooth connects, your application has to be running and listening for bluetooth changes.

If your app goes into background and got recycled, it would not be able to know when the bluetooth is connected, let alone run your logic to send the notifications.
