Is possible to use NearBy API with out Proximity A

问题:

I'm using a beacon that can work either with iBeacon or Eddystone, I create a scanner that has a service in the background which scans each 10 secs for beacons, similar to the android-beacon-library, but I was thinking that I could use the NearBy API to get the beacons with out the scan service, Is that possible?, I don't want to use the ProximityAPI to register the beacons because these beacons will be out there with out the need to register them.

In order to use the Nearby API, your beacons must both be registered with the Google cloud, and have attachments as described here.

The way the Nearby API works, you create a MessageListener and subscribe to get callbacks when beacons are found with messages attached to them:

When subscribing, your app will automatically receive any messages that you've attached to BLE beacons, in addition to any messages published by your app on other devices.

If there aren't any messages attached to them, you won't get any callbacks
