ios - iOS 设备可以与 BT 设备通信吗？

Question

只要我知道如果 BT 设备符合 MFI，iOS 设备可以与 BT 设备通信。但是有朋友说苹果在推出BLE设备后就不再支持BT设备了。我的理解是，如果 BT 设备符合 MFI，iOS 设备可以使用外部附件框架与 BT 设备通信？搜索了很多，找不到来自苹果的任何有用的文档。任何帮助是极大的赞赏

Answer 1

You can connect to Bluetooth Low Energy (BLE) aka Bluetooth Smart or Bluetooth 4.0 devices using the Core Bluetooth framework. BLE devices are specifically excluded from the MFI program.

Bluetooth 2.1 devices are covered by the external accessory framework and require membership of the MFI program in order for the device to be certified by Apple.

There are a couple of exceptions to this - some standard profiles such as headset, hands free, audio streaming and keyboards are supported without the device bing MFI certified, but you don't interact with these devices at the Bluetooth level - audio devices are managed through the AV framework and keyboards just send their input to text controls in the same way as the onscreen keyboard
