对retrievePeripherals的RxBluetoothkit调用第二次失败

let manager = BluetoothManager(queue: .main)
manager.state
    .filter { $0 == .poweredOn }
    .take(1)
    .subscribe(onNext: { _ in
        // 初始化完成后再调用retrievePeripherals
    })
    .disposed(by: disposeBag)

let manager = PeripheralManager()
manager.observeState()
    .startWith(manager.state)
    .filter { $0 == .poweredOn }
    .take(1)
    .flatMap { _ in
        manager.requestAuthorization()
    }
    .subscribe(onNext: { _ in
        // 授权完成后再调用retrievePeripherals
    })
    .disposed(by: disposeBag)

let manager = PeripheralManager()
manager.disconnectAllPeripherals()
    .subscribe(onNext: { _ in
        // 断开连接完成后再调用retrievePeripherals
    })
    .disposed(by: disposeBag)
