iOS上的蓝牙与蓝牙低功耗

Question

我正在尝试获取我附近所有蓝牙设备的名称（仅限名称）（经典蓝牙和BLE）。更具体的是我需要知道用户何时靠近他的车载套件设备蓝牙。

我尝试使用CoreBluetoothFramework，但它只能与BLE设备建立连接。

我不确定所有车载套件都使用“Apple的MFi许可证”，因此我不确定我是否可以使用外部附件。

有什么建议？

谢谢

Answer 1

使用IOBluetooth for Bluetooth classic。请参阅IOBluetoothDevice和IOBluetoothDeviceInquiry类。如果您想查看任何设备，您需要同时使用IOBluetooth和Core Bluetooth。在Bluetooth classic下开发新配置文件需要MFi，对于只检测设备的应用程序，您不需要它。

对于iOS，您可以尝试使用适用于Bluetooth经典的ExternalAccessories框架（不支持IOBluetooth）。有关详细信息，请参阅此问题：How to use bluetooth classic instead of le
