It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1-6, the present invention provides some embodiments of a secure bluetooth connection method for an intelligent device.
As shown in fig. 1, the present invention provides an intelligent system comprising: the intelligent equipment is intelligent equipment worn on a user, the target Bluetooth equipment is equipment capable of establishing Bluetooth connection with the intelligent equipment, the target Bluetooth equipment is generally used for controlling the intelligent equipment, after the intelligent equipment is worn on the user, the target Bluetooth equipment is in Bluetooth connection with the intelligent equipment, data transmission is achieved, and control instructions can be sent to control the intelligent equipment through Bluetooth connection. The smart device comprises a smart earphone, a smart watch, smart eyes and the like, the smart eyes can be smart AR glasses and the like, and the target Bluetooth device comprises a smart phone, a smart tablet, a computer and the like.
Specifically, as shown in fig. 2, the smart device includes: the Bluetooth Device comprises a Bluetooth management module (Manager) and a Bluetooth instance module (Device), wherein the Bluetooth management module is used for scanning a target Bluetooth Device, and the Bluetooth instance module is used for being connected with the target Bluetooth Device.
As shown in fig. 3 to fig. 5, the method for secure bluetooth connection of an intelligent device according to the present invention includes the following steps:
and S100, the intelligent equipment scans whether target Bluetooth equipment exists around.
And S200, when the target Bluetooth equipment exists, the intelligent equipment is in communication connection with the target Bluetooth equipment, and the target Bluetooth equipment is verified.
And step S300, when the verification fails, the intelligent equipment updates the verification code and continues to perform verification until the verification succeeds, the intelligent equipment updates the verification code, and the intelligent equipment is paired with the target Bluetooth equipment to complete Bluetooth connection.
Specifically, when the intelligent device is checked, the intelligent device does not adopt non-key checking or fixed key checking, but adopts a mode of updating the check code to check, and whether the checking is successful or failed, the intelligent device can update the check code, so that the check code is leaked, and other Bluetooth devices acquire the check code of the intelligent device.
Specifically, the bluetooth connection between the smart device and the target bluetooth device is divided into a third phase, which is a scanning phase, a verification phase, and a pairing phase. The method comprises the steps that the Bluetooth of the intelligent device and the Bluetooth of the target Bluetooth device need to be started in a scanning stage, the target Bluetooth device starts to be scanned after the Bluetooth of the intelligent device is started, and the intelligent device can scan other Bluetooth devices besides the target Bluetooth device during scanning. It should be noted that, the target bluetooth device may control the intelligent device by installing an app and other virtual controllers, and only when the target bluetooth device is scanned, the scanning is finished, and the scanning stage is completed. Other bluetooth devices are scanned and the scan is not finished.
In order to accurately scan the target bluetooth device, step S100 specifically includes:
and step S110, the Bluetooth management module of the intelligent device sends scanning information to scan the target Bluetooth device.
And step S120, when the Bluetooth management module of the intelligent device receives the scanning result sent by the target Bluetooth device and the scanning result meets a preset condition, the target Bluetooth device exists and the scanning is finished.
Step S130, when the Bluetooth management module of the intelligent device does not receive the scanning result or the received scanning result does not meet the preset condition, the target Bluetooth device does not exist, the scanning information is continuously sent to continuously scan the target Bluetooth device, and the scanning is finished until the scanning stopping instruction is received.
Specifically, as shown in fig. 3, the smart device sends out scanning information to perform scanning. And after receiving the scanning information, the target Bluetooth device (or other Bluetooth devices) sends a scanning result to the intelligent device, and if the scanning result meets a preset condition, the target Bluetooth device is indicated to exist. If the scanning result received by the intelligent device does not meet the preset condition or the scanning result is not received, it is indicated that the target Bluetooth device does not exist, the scanning information is continuously sent to continuously scan the target Bluetooth device until the scanning stopping instruction is received, and the scanning stopping instruction can be the Bluetooth of the intelligent device.
The scanning information carries a supplier identification code (VID) and a product identification code (PID), when the target bluetooth device (or other bluetooth devices) receives the scanning information, the supplier identification code (VID) and the product identification code (PID) are obtained, some bluetooth devices cannot control the intelligent device, the local supplier identification code and the local product identification code cannot be stored, and the two cannot be compared, so that the scanning result cannot be sent after the scanning information is received. Some bluetooth devices also store local supplier identification codes and local product identification codes, and compare the two, but the supplier identification codes in the scanning information are not consistent with the local supplier identification codes, or the product identification codes in the scanning information are not consistent with the local product identification codes, then the sent scanning result is that the supplier identification codes are not consistent, or the product identification codes are not consistent. The target Bluetooth device stores a local supplier identification code and a local product identification code, compares the supplier identification code with the local supplier identification code in the scanning information, compares the product identification code with the local product identification code in the scanning information, and sends a scanning result (namely a comparison result) to the intelligent device. And after receiving the scanning result, the intelligent device judges whether the scanning result meets a preset condition, wherein the preset condition is that the supplier identification code is consistent and the product identification code is consistent.
From the above, the scanning result includes: the vendor identification code is not consistent, the vendor identification code is consistent, the product identification code is not consistent, and the product identification code is consistent. And when the scanning result meets the preset condition, namely the scanning result is that the supplier identification codes are consistent and the product identification codes are consistent, the preset condition is met. If the scanning result is that the supplier identification code is inconsistent and the product identification code is consistent, the supplier identification code is consistent and the product identification code is inconsistent, the supplier identification code is inconsistent and the product identification code is inconsistent, the preset condition is not met.
Step S200 specifically includes:
step S210, the Bluetooth instance module of the intelligent device sends a connection request to the target Bluetooth device.
Step S220, the bluetooth instance module of the intelligent device receives the connection success callback information sent by the target bluetooth device, so as to establish a communication channel with the target bluetooth device to implement communication connection.
And step S230, the intelligent equipment sends a check code to the target Bluetooth equipment through the communication channel so as to check.
Specifically, as shown in fig. 4, the intelligent device sends a connection request to the target bluetooth device, and the target bluetooth device sends connection success callback information to the intelligent device after receiving the connection request, so that the intelligent device and the target bluetooth device establish a communication channel to realize communication connection. Specifically, the communication channel includes: BLE channel and classic bluetooth channel. And the intelligent device is connected with a BLE (Bluetooth low energy) channel established by the target Bluetooth device. The smart device may perform a check based on the BLE channel, and specifically, the smart device transmits a check code to the target bluetooth device through the BLE channel to perform the check.
Specifically, a local check code is stored in the target bluetooth device, after the target bluetooth device receives the check code sent by the intelligent device through the BLE channel, the check code is compared with the local check code, when the check code is consistent with the local check code, the check is successful, and the target bluetooth device sends callback information of successful check to the intelligent device through the BLE channel; when the Bluetooth device and the Bluetooth device are inconsistent, the verification fails, and the target Bluetooth device sends callback information of the verification failure to the intelligent device through the BLE channel.
Step S300 specifically includes:
step S310, when the smart device receives the callback information of the verification failure sent by the target bluetooth device through the BLE channel, the smart device updates the verification code according to a preset rule, and sends the updated verification code to the target bluetooth device through the BLE channel to continue the verification.
Step S320, when the intelligent device receives callback information of successful verification sent by the target bluetooth device through the BLE channel, the intelligent device updates the verification code according to a preset rule, and sends a pairing command to the target bluetooth device through the BLE channel, so that the target bluetooth device stores the first classic bluetooth address carried in the pairing command.
And S330, the intelligent device receives classical Bluetooth pairing connection information sent by the target Bluetooth device through the classical Bluetooth channel.
Step S340, the intelligent device sends a pairing request to the target Bluetooth device through the classic Bluetooth channel; the pairing request carries a second classic bluetooth address.
And S350, the intelligent equipment receives comparison success information of the classic Bluetooth address through the classic Bluetooth channel so as to complete Bluetooth connection.
Specifically, when the check code is successfully checked, the target bluetooth device updates the local check code, sends callback information of successful check to the intelligent device through the BLE channel, and the intelligent device receives the callback information of successful check sent by the target bluetooth device through the BLE channel, updates the check code and pairs with the target bluetooth device. When the check code fails to be checked, the target Bluetooth device updates the local check code and sends check failure callback information to the intelligent device through the BLE channel, and the intelligent device receives the check failure callback information sent by the target Bluetooth device through the BLE channel, updates the check code and continues checking. No matter the check code is checked successfully or fails, the target Bluetooth device can update the local check code and the intelligent device can update the check code, and even if the check code is received by other Bluetooth devices in the previous check process, the check code cannot be checked successfully with the intelligent device, and the Bluetooth connection cannot be achieved.
When the intelligent device and the target Bluetooth device establish a communication channel, a classic Bluetooth channel can be established. As shown in fig. 5, in the pairing process, the smart device sends a pairing command to the target bluetooth device through the BLE channel, and after receiving the pairing command, the target bluetooth device stores a first classic bluetooth address carried in the pairing command, and then sends classic bluetooth pairing loopback information to the smart device through the classic bluetooth channel. The intelligent device receives the classic Bluetooth pairing connection information through the classic Bluetooth channel, the intelligent device sends a pairing request to the target Bluetooth device through the classic Bluetooth channel, the target Bluetooth device receives the pairing request through the classic Bluetooth channel, obtains a second classic Bluetooth address carried by the pairing request, compares the first classic Bluetooth address with the second classic Bluetooth address, if the two addresses are consistent, the comparison is successful, the target Bluetooth device sends comparison success information to the intelligent device through the classic Bluetooth channel, and Bluetooth connection between the intelligent device and the target Bluetooth device is achieved. If the Bluetooth address and the Bluetooth address are not consistent, the intelligent device continues to send a pairing command to the target Bluetooth device through the BLE channel, so that the target Bluetooth device stores the first typical Bluetooth address carried by the pairing command, and if the Bluetooth address and the Bluetooth address are still not successfully compared, the Bluetooth connection is ended.
It should be noted that, when the bluetooth connection is performed, the pairing command is directly and automatically sent, the bluetooth connection is realized by comparing the classic bluetooth addresses, and the classic bluetooth device enters the pairable mode without physical keys or commands, that is, only the bluetooth of the intelligent device and the bluetooth of the target bluetooth device are required to be ensured to be in an open state, so that the automatic bluetooth connection between the intelligent device and the target bluetooth device is realized based on the method of the present invention, and the bluetooth connection between the intelligent device and the target bluetooth device is simplified.
It can be understood that, during pairing, the smart device does not directly initiate pairing to the target bluetooth device, and even if the smart device initiates pairing to the target bluetooth device, the target bluetooth device also rejects pairing (if pairing is not rejected, the smart device needs to enter a pairable mode through a physical button or a command, which is cumbersome to operate), so that the smart device sends a pairing command to the target bluetooth device through the BLE channel to perform automatic pairing.
As shown in fig. 6, after bluetooth connection, when entering a data transmission phase, the bluetooth instance module of the smart device provides a command sending task thread and a command receiving thread, each thread has a command queue to buffer commands, so that commands are safer and command sending/receiving is not blocked.
Referring to fig. 1 to fig. 6, the present invention provides some embodiments of a secure connection method for bluetooth of an intelligent system. The intelligent system comprises: intelligent device and target bluetooth device.
As shown in fig. 3 to 5, the method for secure bluetooth connection in an intelligent system according to the present invention includes the following steps:
step A100, the intelligent device scans whether the target Bluetooth device exists around.
And A200, when the target Bluetooth equipment exists, the intelligent equipment is in communication connection with the target Bluetooth equipment and checks.

Specifically, the smart device scans first, and when the target bluetooth device exists in a preset range around the smart device, the target bluetooth device is checked. Regardless of whether the verification succeeds or fails, the intelligent device can update the verification code, the target Bluetooth device can update the local verification code, and even if the verification code leaks, the intelligent device cannot be connected by other Bluetooth devices due to the fact that the verification code of the intelligent device is updated, and safety problems occur.

The communication channel can comprise a BLE channel and can also comprise a classic Bluetooth channel.
As shown in fig. 4, before the intelligent device and the target bluetooth device in the intelligent system are connected via bluetooth, the target bluetooth device stores a local check code.
