使用蓝牙低功耗连接iPhone 4s和iPad3

Question

Can anyone point me to an example of connecting an iPhone 4S to an iPad 3 using BLE?

I have written a sample App and when I use CBCentralManager like this:

[centralManager scanForPeripheralsWithServices:uuidArray options:options];

To scan for devices the iPhone and iPad do not seem to see each other.

Thanks for the help

Answer 1

The iPad is not a Bluetooth Low Energy device. A BLE device is typically a wristwatch, heart-rate monitor etc.

This is why you can't see the iPad using CoreBluetooth.

Consider using GameKit for iPhone-iPad bluetooth communication?

Answer 2

The new iPad (3rd Gen) does have Bluetooth 4.0, but you cannot use BT4.0 to communicate between two iOS devices.

You can only communicate with external sensors.

Answer 3

In addition to the other answers, the bluetooth specification states that dual mode blend devices will use the classic bt radio and not the ble radio. You can only use the ble radio with single mode ble devices.

Answer 4

如果你想在蓝牙低功耗的两个iDevices之间进行通信，你必须等待iOS 6，这将支持BLE上的服务器功能。
