iOS Swift CentralManager didConntectPeripheralは決して呼び出されません

Question

私はBluetoothとSwiftの両方が新しく、今はBluetoothデバイス（Arduino HM-10）に接続してサービスを取得しようとしています。私が抱えている問題は、デバイスに接続した後、centralManager didConnectPeripheralメソッドが呼び出されないことです。ここに私のコードは

import UIKit 
import CoreBluetooth 

class ViewController: UIViewController, CBCentralManagerDelegate, CBPeripheralDelegate { 

    var manager:CBCentralManager! 
    var peripheral:CBPeripheral! 


    let BubbleWallBluetoothName = "TestBluetooth" 
    let BEAN_SCRATCH_UUID = 
     CBUUID(string: "a495ff21-c5b1-4b44-b512-1370f02d74de") 
    let BEAN_SERVICE_UUID = 
     CBUUID(string: "a495ff20-c5b1-4b44-b512-1370f02d74de") 

    override func viewDidLoad() { 
     super.viewDidLoad() 
     manager = CBCentralManager(delegate: self, queue: nil) 
    } 

    func centralManagerDidUpdateState(_ central: CBCentralManager){ 

     switch (central.state) 
     { 
     case . unsupported: 
      print("BLE is unsupported") 
     case.unauthorized: 
      print("BLE is unauthorised") 
     case.unknown: 
      print("BLE is unknown") 
     case.resetting: 
      print("BLE is resetting") 
     case.poweredOff: 
      print("BLE is powered off") 
     case.poweredOn: 
      print("BLE is powered on") 
      central.scanForPeripherals(withServices: nil, options: nil) 
     } 

    } 

    func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String : Any], rssi RSSI: NSNumber) { 
     print("Found Device " + peripheral.name!) 


     let device = (advertisementData as NSDictionary).object(forKey: CBAdvertisementDataLocalNameKey) as? NSString 

     if (device?.contains(BubbleWallBluetoothName) == true) { 
      self.manager.stopScan() 

      self.peripheral = peripheral 

      self.peripheral.delegate = self 

      manager.connect(peripheral, options: nil) 
     } 
    } 


    //This function never gets called 
    func centralManager(central: CBCentralManager, didConnectPeripheral peripheral: CBPeripheral) { 
     peripheral.discoverServices(nil) 
     print("We are connected to BT"); 
    } 
} 

Answer 1

OKですので、私はそれがとても

func centralManager(_ central: CBCentralManager, didConnect peripheral: CBPeripheral) { 
     peripheral.discoverServices(nil) 
     print("We are connected to BT"); 
    }
