BluetoothLE read device RSSI without connecting?

Extensions

I need to scan a number of BLE enabled devices continuously and look for their RSSI.
So what I’ve so far tried is:

  1. Get the device RSSI by using the “FoundDeviceRSSI index” - But for this I need to manually choose the device from the list.
  2. Use the “when BluetoothLE1.RSSIChanged” function, but I can’t figure out a way to select which device’s RSSI is shown from the list.

I can read the RSSI of the connected device and work with it very well, however I just can’t understand how to read the RSSI of a specific device without connecting to it.

Anybody got any idea?

Edit: Here’s a part of the blocks I am using. Once the ClockStopScan timer runs, it stops scanning for devices and I want it to give me the advertising data for the specified device [given by the address and UUID], however, it throws the following error,
Attempt to invoke virtual method 'android.bluetooth.le.ScanRecord android.bluetooth.le.ScanResult.getScanRecord()' on a null object reference

I also tried to change the UUID to one of the GATT characteristics addresses, but it gives the same error. Any sort of help would be much appreciated!

Have you been able to accomplish this yet as I have a project that requires monitoring the RSSI of a BLE beacon and i have not been able to succeed yet. I can scan and receive every BLE device within range but cannot determine how to monitor a single device (beacon) RSSI by name or by address.
