iBeacons seem to broadcast their txPower parameter (report RSSI power at 1 meter distance) which is used in calculating beacon.accuracy
and beacon.proximity
properties (details on iBeacon advertisements packet can be found here).
However, CLBeacon
class does not seem to have a property for txPower. Is there a way I can get txPower using Core Location framework, or need I to go down to Core Bluetooth? The reason I need this, is I want to experiment with custom beacon accuracy/proximity calculation for very quick beacon immediate range discovery. In this circumstances reverse calculating txPower from accuracy
is no helper.
