Reading Tag's BLE RSSI (MDEK kit)

How could I read the BLE rssi of Tag as seen by the Android Phone while the position calculation is continuously running and getting updated in the Sample Android App ( when seen in Grid View) ? Is there any Android API in DRTLS sample app or PANS library which could be referred for this ?

I observed that the even in ‘Network Details’ tab in the sample app, only the RSSI of Anchors gets updated(through BLEpresence and BLE deviceDiscovery), when the position calculation is going on . RSSI of Tag gets updated only when the position calculation/update stops. Is there a way to read that even while the update is happening?
