BLE 设备可以直接连接到 watchOS 应用程序吗？

        }
    }
}

func centralManager(_ central: CBCentralManager, didConnect peripheral: CBPeripheral) {
}

func centralManager(_ central: CBCentralManager, didFailToConnect peripheral: CBPeripheral, error: Error?) {
}

func centralManager(_ central: CBCentralManager, didDisconnectPeripheral peripheral: CBPeripheral, error: Error?) {
}
}

我想将 BLE 设备直接连接到我的 watchOS。现在我可以检查中央管理器是否开始扫描设备，但我从来没有得到一个设备。 我用单例类尝试过，然后直接使用它但没有取得任何成功。 如果上面的代码片段有什么问题，请给我建议。任何帮助将不胜感激。
