Get RSSI value while using ProximitySDK?

I am using ProximitySDK. I am creating different zone for a beacon using ProximityZone feature.
Is it possible to get the RSSI value of the beacon while “onEnter” callback is called?

There’s not. The whole idea of the Proximity SDK is to abstract away all the low-level stuff like RSSI, instead have a simple API to trigger some actions when close to a beacon. What would you want to use the RSSI for?
