More Frequent BLE Scan Results

[swanav@erangroup]

I am working on a BLE Product which connects to a remote device when detected within a certain proximity (based on the RSSI values).
After switching on the scanning, I receive Scan Results almost every 2 seconds. The thing is I want the RSSI tracking to be smoother, 300 ms at max, so that connection is almost instantaneous when the device is found in the range. I have tried fiddling with the Scan Interval and Durations, but the frequency at which the application receives the scan results is unaffected. Can someone please give me some pointers on how that parameter can be changed?
