私は周辺機器として私のiPhoneを使用し、中心として私のMacを使用してコアのBluetoothのアプリケーションを作っている。私のiPhoneはオンになって広告を出していますが、ブルートゥースブラウザでは他のiPhoneやMacでそれを発見することはできません。しかし、私の友人のAndroidの携帯電話はそれを発見することができます。どうしたの？ のiOSエンド：私のCBPeripheralManagerは広告を表示しますが、検出できないのはなぜですか？

Bluetoothの状態がオンと広告されていることをプリントアウトしています。 Macの場合：
import Cocoa
import CoreBluetooth
class ViewController: NSViewController, CBCentralManagerDelegate {
var centralManager: CBCentralManager!
override func viewDidLoad() {
super.viewDidLoad()
centralManager = CBCentralManager(delegate: self, queue: nil)
// Do any additional setup after loading the view.
}
override var representedObject: Any? {
didSet {
// Update the view, if already loaded.
}
}
func setupBT() {
}
func centralManagerDidUpdateState(_ central: CBCentralManager) {
var statusMessage = ""
switch central.state {
case .poweredOn:
centralManager.scanForPeripherals(withServices: [CBUUID(string: "CAB1B028-2243-4F2C-A2F1-3BE5AD51AD61")], options: nil)
statusMessage = "Bluetooth Status: Turned On"
case .poweredOff:
statusMessage = "Bluetooth Status: Turned Off"
case .resetting:
statusMessage = "Bluetooth Status: Resetting"
case .unauthorized:
statusMessage = "Bluetooth Status: Not Authorized"
case .unsupported:
statusMessage = "Bluetooth Status: Not Supported"
default:
statusMessage = "Bluetooth Status: Unknown"
}
print(statusMessage)
}
func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String : Any], rssi RSSI: NSNumber) {
print("Discovered")
}
}
電源が入っていても何も発見されていません。
周辺機器をどのように見つけようとしていますか？ –
設定でブルートゥースデバイスブラウザを使用してもそれを検出できず、どちらも私のMacコアのブルートゥースアプリケーションではありませんでした。必要に応じてMacコードを提供することができます –
@BrandonA Macコードを追加しました –
