Bluetooth technology is favored, in addition to the high transmission rate of bluetooth connection, pairing and authentication are required to be performed when bluetooth connection is established between bluetooth devices, so that the security of bluetooth connection is relatively high.
The Bluetooth communication belongs to a one-to-one communication mode, two devices for establishing Bluetooth connection are divided into a master device and a slave device, if the master device needs to be connected with the slave device, parameters such as pairing passwords of the slave device need to be known, the slave device is paged through Bluetooth broadcasting, paging is received by the slave device, after the pairing parameters are verified, the paging of the master device is responded, and then the Bluetooth connection is established.
Many simple bluetooth peripherals, such as bluetooth headsets, default to slave mode at the factory, and the pairing password defaults to "0000" or "1111" to facilitate quick connection by the user. Obviously, there are many safety concerns with this approach. Therefore, more and more bluetooth devices, especially those with higher requirements for data security, will adopt a more secure device pairing strategy to establish bluetooth connection. For the convenience of users, manufacturers of bluetooth devices often integrate the pairing policy into an SDK (user development kit) of the device to provide the user, and the smart control device can complete connection establishment with the bluetooth device by calling a corresponding interface function in the SDK of the bluetooth device. Along with the popularization of the application of intelligent mobile terminals such as smart phones, a plurality of Bluetooth devices customize APP (application programs) aiming at the operating system of the terminal, the SDK of the APP integrated Bluetooth device is used for establishing Bluetooth connection between the terminal where the APP is located and the Bluetooth device by calling the corresponding interface function of the SDK of the Bluetooth device. Like this, the bluetooth pairs the parameter and can set for wantonly, and encapsulates in SDK or APP, and the terminal obtains the bluetooth through installation APP and pairs the parameter, can strengthen the security that the bluetooth pairs the parameter, improves the security that the bluetooth is connected.
Generally, a terminal is connected with bluetooth devices through bluetooth, an operating system of the terminal considers that the operating system is a bluetooth connection resource, one terminal can be connected with a plurality of bluetooth devices through bluetooth respectively, but only one bluetooth connection can be established between one terminal and a specific bluetooth device. While one bluetooth connection resource is typically allocated for exclusive use by the APP initiating the bluetooth connection, in most cases this may suffice. However, for a bluetooth device such as a bluetooth credit card, there may be a plurality of APPs (e.g., APPs of multiple banks) in a terminal that need to transmit data by using a bluetooth connection between the terminal and the bluetooth device (e.g., bluetooth credit card), that is, a coordination mechanism for negotiating with each other to manage the same bluetooth connection resource needs to be established between the APPs, otherwise, the bluetooth device (bluetooth credit card) can only be used by one APP (bank APP that initiates bluetooth connection first), and other APPs (other bank APPs) may have a problem that the bluetooth device (bluetooth credit card) cannot be found.

All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without inventive step, are within the scope of the present invention.
In the embodiment of the present invention, the smart terminal includes a mobile phone, a tablet computer, and the like, and for convenience of description, the operating system is an iOS system of apple inc. Because the sandbox mechanism of system, unable direct exchange information between the APP in the system, first APP promptly can't direct access second APP's data, and first APP also can't direct push data give second APP simultaneously. However, there are some system-shared resources in iOS systems that can be accessed by individual APPs, such as: system clipboard, key string, file system, etc.
In this embodiment, in order to allow the APPs to negotiate with each other to manage the same bluetooth connection resource, information exchange is performed by means of the system shared resource.
Fig. 1 is a schematic flow chart illustrating an implementation of a management method for bluetooth connection resources according to an embodiment of the present invention, as shown in fig. 1, the method includes:
specifically, in this embodiment, the system shared resource refers to a system clipboard; when the APP1 needs to exchange information with a target Bluetooth device and the APP1 needs to establish Bluetooth connection with the target Bluetooth device through a system, the APP1 writes a specific character string into a system clipboard, wherein the character string is predefined as a Bluetooth connection resource release notification; if the APP2 runs in the background and occupies the Bluetooth connection resource, after the APP2 reads the character string from the system clipboard, the APP2 executes the operation of disconnecting the Bluetooth connection and releases the Bluetooth connection resource occupied by the APP 3526; here, the APP1 caches the current state of the system clipboard before writing a particular string into the system clipboard;
specifically, APP1 waits a first preset time, for example: 2 seconds later, the APP1 restores the original state of the system clipboard according to the state of the system clipboard cached in advance; the APP1 initiates Bluetooth connection paging to the target Bluetooth device at this time, and then the APP1 occupies the Bluetooth connection resource corresponding to the target Bluetooth device. Even if APP2 has occupied the Bluetooth connection resource before, the Bluetooth connection resource is released at this time, APP1 can normally connect with the target Bluetooth device, and if the Bluetooth connection resource has not been occupied before, APP1 can normally connect with the target Bluetooth device at this time.
After that, when the APP1 enters the background, the system is applied for continuing to execute the background task for a second preset time, for example: 2 minutes, during this period, APP1 still occupies the bluetooth connection resource, and in order not to hinder other APPs from using the bluetooth connection resource, APP1 polls the system shared resource, i.e. the system clipboard, within the second preset time, and when APP1 runs in the background, after checking that the system clipboard contains a specific character string indicating the meaning of releasing the notification of the bluetooth connection resource, APP1 can disconnect its bluetooth connection and release its occupied bluetooth connection resource.
As can be seen from the above process, the bluetooth connection resource negotiated by APP1 and APP2 is for one target bluetooth device, and in different application scenarios, the identities of APP1 and APP2 may be interchanged completely, that is, APP1 preemptively occupies the target bluetooth connection resource, while APP2 is an application that later needs the target bluetooth connection resource. That is, the above scheme is not particularly directed to a certain type of APP, but is directed to a certain type of bluetooth device, and such bluetooth device needs to be used after different APPs establish bluetooth connection with it through the bluetooth module of the intelligent terminal. Therefore, in order to improve the security and reliability of the bluetooth connection without causing device confusion, the feature information of the target bluetooth device, i.e., the feature information of the target bluetooth connection, is preferably included in the above-mentioned release bluetooth connection resource notification, i.e., the specific character string. Here, the feature information may be a manufacturer name, a device number, and the like of the bluetooth device. For example, the specific character string is: feature information _ disconnectable.
