Bluetooth is a wireless technical standard, and can realize short-distance data exchange among fixed equipment, mobile equipment and a building personal area network; in order to ensure the security and convenience of bluetooth communication, the bluetooth standard specifies that the first communication authentication between a bluetooth device and a device to be connected, i.e. a bluetooth pairing process, can be completed in a pairing manner. In the bluetooth pairing process, the bluetooth pairing generally means that the bluetooth device initiates a pairing request to the device to be connected, waits for a user to input a pin code and judges whether the pin code input by the user is correct or whether the user confirms the pairing request on the device to be connected to complete the pairing process, and then performs subsequent normal communication.
However, in the development of the communication apparatus of the iOS system, since the iOS system is not open source, the development of bluetooth 4.0 can use only the bluetooth framework provided by the iOS system. When a bluetooth framework is used for interacting with a device to be connected (such as a bluetooth mouse, a bluetooth intelligent key device and the like), pairing operations of all bluetooth devices are realized by the bottom layer encapsulation of the iOS system, and the upper layer application cannot know the pairing state of the iOS system and the bluetooth device, so that blindly sending data can conflict with a pairing frame popped up by the iOS system, and the device to be connected cannot be used; even if the bluetooth device has been disconnected from the iOS system, it is not known whether or not the connection has been disconnected and the reason for the disconnection cannot be distinguished.
