iOS 上的蓝牙与低功耗蓝牙

Question

I'm trying to get the name (only the name) of all bluetooth devices near me (classic bluetooth and BLE). to be more specific i need to know when the user is near his car kit device bluetooth.

I tried using CoreBluetoothFramework but it can only create connection with BLE devices.

I'm not sure that all the car kits uses "Apple's MFi license" so i'm not sure i can use External Accessory.

Answer 1

Use IOBluetooth for Bluetooth classic. See for example IOBluetoothDevice and IOBluetoothDeviceInquiry classes. If you want to see any device you need to use both IOBluetooth and Core Bluetooth. The MFi is needed for developing new profiles under Bluetooth classic, you shouldn't need it for an application that just detects devices.

For iOS you can try the ExternalAccessories framework for Bluetooth classic (IOBluetooth is not supported). See this question for relevant details: How to use bluetooth classic instead of le
