is there a way to show the beacon direction as an arrow point the direction to the beacon? I know it is possible to change the color according to the proximity of the beacon but what I need is a direction to find the beacon.
You can't do this just with one beacon as all you have is the received signal strength (RSSI). The Determining Location Using Bluetooth Beacons article explains more and references a paper that shows a workaround that might help when using just one beacon.
