Import required frameworks.
import UIKit
import CoreBluetooth
import Foundation
Define a UIViewController class implementing the CBCentralManagerDelegate and CBPeripheralDelegate protocols.
class InactiveVC: UIViewController, CBCentralManagerDelegate, CBPeripheralDelegate ... {
var manager : CBCentralManager!
override func viewDidLoad() {
super.viewDidLoad()
manager = CBCentralManager(delegate: self, queue: nil)
...
}
...
}
Handle updates of the CBCentralManager state. Start scanning for CloseBeacon peripherals if/when the CBCentralManager state indicates "PoweredOn".
func centralManagerDidUpdateState(central: CBCentralManager) {
switch central.state {
case .Unknown:
print("BT state is unknown")
break;
case .Resetting:
print("BT is resetting")
break;
case .Unsupported:
print("BT is unsupported")
break;
case .Unauthorized:
print("BT is unauthorized in this app")
break
case .PoweredOff:
print("BT is powered off")
break;
case .PoweredOn:
print("BT is powered on")
manager.scanForPeripheralsWithServices(nil,
options: [CBCentralManagerScanOptionAllowDuplicatesKey : true])
break;
}
}
Handle discovered CLOSE Beacons.
func centralManager(central: CBCentralManager,
didDiscoverPeripheral peripheral: CBPeripheral,
advertisementData: [String : AnyObject],
RSSI: NSNumber) {
if peripheral.name != nil {
if peripheral.name == "closebeacon.com" {
for t in advertisementData {
// Look for Manufacturer Specific Data.
if t.0 == "kCBAdvDataManufacturerData" {
let msd = NSData(data: t.1 as! NSData)
let m = UnsafePointer<UInt8>((msd.bytes))
let serNo = String(format: "%03d-%03d-%03d-%03d-%03d-%03d",
arguments: [m[6],m[5],m[4],m[3],m[2],m[1]])
print("Serial No: \(serNo)")
}
}
}
}
}
In order to find CLOSE Beacons that has been activated as iBeacon, you need to know at least the proximity UUID that was used when the CloseBeacon was activated.
First import the required frameworks.
import UIKit
import CoreLocation
Define a UIViewController implementing the CLLocationManagerDelegate protocol.
class ActiveVC: UIViewController, CLLocationManagerDelegate ... {
// Proximity UUIDs to be found.
var knownUuids : [NSUUID] = []
let manager = CLLocationManager()
override func viewDidLoad() {
super.viewDidLoad()
manager.delegate = self
// In this example we request location awareness to be enabled only
// when the app is active.
if (CLLocationManager.authorizationStatus() != CLAuthorizationStatus.AuthorizedWhenInUse) {
manager.requestWhenInUseAuthorization()
}
...
}
...
}
Start ranging for CLOSE Beacons using known proximity UUIDs.
private func startRanging() {
for uuid in knownUuids {
print("Start ranging for uuid: \(uuid.UUIDString), fake id: \(uuid.hashValue)")
let r = CLBeaconRegion(proximityUUID: uuid, identifier: "\(uuid.hashValue)")
manager.startRangingBeaconsInRegion(r)
}
}
Handle found beacons.
func locationManager(manager: CLLocationManager,
didRangeBeacons beacons: [CLBeacon], inRegion region: CLBeaconRegion) {
for b in beacons {
let uuidString = b.proximityUUID.UUIDString
print("Proxy UUID: \(uuidString)")
print("Major: \(b.major), Minor: \(b.minor), RSSI: \(b.rssi) dBm")
...
}
}
