I've written my own little BLE scanning service that is triggered via an alarm every 3-5 seconds. It scans for 1.1 seconds to get teh beacons around it and then transforms the RSSI signal into a rough proximity.
I am now considering the Radius Networks Android iBeacon service, but I am wondering how I could realize the same background scanning.
e.g.: I want the beacons scannign to start annd run in the background and receive Intents into a broadcast receiver to decide what I do with the beacons scanned.
Are there soem examples and is there an estimate how much battery this consumes?
