Can't detect beacon in CLLocationManager
I want to detect and capture how far a beacon is from my device. I find my Beacon using CBCentralManager, but when I use CLLocation to capture the metrics, in my LocationManager function I can't find my beacon. The beacon parameter is empty. CoreBluetoothTest import SwiftUI import CoreBluetooth class CoreBluetoothTest: NSObject, ObservableObject { private var centralManager: CBCentralManager? private var peripherals: [CBPeripheral] = [] @Published var peripheralsNames: [String] = [] private var devideCount: Int = 0 private var beaconDetector = BeaconDetector() override init() { super.init() self.centralManager = CBCentralManager(delegate: self, queue: .main) } } extension CoreBluetoothTest: CBCentralManagerDelegate { func centralManagerDidUpdateState(_ central: CBCentralManager) { if central.state == .poweredOn { self.centralManager?.scanForPeripherals(withServices: nil) } } func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData data: [String : Any], rssi RSSI: NSNumber) { if !peripherals.contains(peripheral) { devideCount += 1 self.peripherals.append(peripheral) print("Device número \(devideCount): \(peripheral.identifier), RSSI: \(RSSI)") //let nearbyInteraction = NearbyInteractionTest() //nearbyInteraction.startupMPC(identifier: peripheral.identifier.uuidString) central.connect(peripheral) print("Efetuando conexão \(peripheral.state)") // 3 = Desconectando, 2 = Conectado, 1 = conectando, 0 = Desconectado if peripheral.name == nil { self.peripheralsNames.append("\(peripheral.identifier.description) RSSI: \(RSSI)") } else { self.peripheralsNames.append(peripheral.name ?? "Dispositivo sem nome") } } } func centralManager(_ central: CBCentralManager, didDisconnectPeripheral peripheral: CBPeripheral, error: Error?) { print("Omg! conexão falhada com: \(peripheral.identifier), Status: \(peripheral.state)") // 3 = Desconectando print("Error: \(error)") central.connect(peripheral) } func centralManager(_ central: CBCentralManager, didConnect peripheral: CBPeripheral) { print("Conexão realizada com sucesso com: \(peripheral.identifier)") beaconDetector.startScanning(myID: peripheral.identifier) } } BeaconDetector import Combine import Foundation import CoreLocation extension BeaconDetector: CLLocationManagerDelegate{ } class BeaconDetector: CLLocationManager, ObservableObject { var didChange = PassthroughSubject<Void, Never>() var locationManager: CLLocationManager? var lastDistance = CLProximity.unknown override init() { super.init() locationManager = CLLocationManager() locationManager?.delegate = self locationManager?.requestWhenInUseAuthorization() } func locationManager(manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) { if status == .authorizedWhenInUse { if CLLocationManager.isMonitoringAvailable(for: CLBeaconRegion.self) { if CLLocationManager.isRangingAvailable() { // we are ready to go } } } } func startScanning(myID: UUID) { let constraint = CLBeaconIdentityConstraint(uuid: myID, major: 1, minor: 50000) let beaconRegion = CLBeaconRegion(beaconIdentityConstraint: constraint, identifier: "MyBeacon") locationManager?.startMonitoring(for: beaconRegion) locationManager?.startRangingBeacons(satisfying: constraint) print("Regioes \(locationManager?.monitoredRegions)") print("RangedBeaconConstraints \(locationManager?.rangedBeaconConstraints)") } func locationManager(_ manager: CLLocationManager, didEnterRegion region: CLRegion) { } func locationManager(_ manager: CLLocationManager, didExitRegion region: CLRegion) { } func locationManager(_ manager: CLLocationManager, monitoringDidFailFor region: CLRegion?, withError error: Error) { } func locationManager(_ manager: CLLocationManager, didRangeBeacons beacons: [CLBeacon], in region: CLBeaconRegion ) { if let beacon = beacons.first { print("Encontrou Beacon") update(distance: beacon.proximity) } else { print("Não localizou o beacon") } } } Logs:
