Sample text

Basic iBeacon Programming Functions iBeacons enable location to be reported to an application through two operations: Monitoring A high-level view of whether a device is within range of a speci‐ fied beacon. It indicates that both the beacon and the mobile device are loosely within the same space, as defined by whatever the transmission characteristics of the beacon are. Ranging Specific to a single beacon, ranging uses its transmissions to estimate the distance from a mobile device to a beacon.

6 With essentially zero security in the protocol, applications have to provide their own defenses against spoofing. Most importantly, applications should be designed so that the mere presence of an iBeacon does not trigger an action with security consequences. Here are a couple approaches for designing defenses into an application: 6 For example, one of the first “treasure hunt” applications was shown at CES in January 2014, and it was promptly reverse engineered by Alasdair Allan and Sandeep Mistry.

Range updates are supplied every second. The Core Location framework summarizes the range into a general description of immediate (within a few centimeters), intermediate (a few meters), and far (the iBeacon’s transmissions are received, but it is more than a few meters away). info NSUUID *myUUID = [[NSUUID alloc] initWithUUIDString:@"24F7B8B3-D124-4B7B-A180-CBA317CC1BB6"]; CLBeaconMajorValue myMajor = 42; CLBeaconMinorValue myMinor = 105; // This region matches on one specific beacon in the UUID CLBeaconRegion *matchThree = [[CLBeaconRegion alloc] initWithProximityUUID:myUUID major:myMajor minor:myMinor identifier:@"matchThree" ]; CLLocationManager *myLocationManager = [[CLLocationManager alloc] init]; // Change to monitor for a specific iBeacon within that UUID [myLocationManager startRangingForBeaconsInRegion:matchThree]; To access ranging data, the framework will trigger the didRangeBea cons method.
