Scanning for beacons is a long task. It can take some seconds to complete and find all available Beacons.
Scan again if the scan finishes if you want.
Scanning every 0,5 seconds will not work i guess
Hi Erel, thank's a lot, it work. Now i have ho read the rssi of a single beacon too fast. I have to know if che beacon is very near to phone. The problem is that the rssi do not refresh too fast.
