Fig. 2 is a schematic flowchart illustrating the method for bluetooth connection in the present embodiment when applied to a user equipment. As shown in fig. 2, the bluetooth automatic connection method includes the following steps:
step S110: when a Bluetooth demand signal sent by an application program is detected, starting Bluetooth connection and judging whether the Bluetooth connection is the first connection;
step S120: when the Bluetooth connection is the first connection, acquiring an authentication code from the vehicle-mounted equipment through a non-Bluetooth wireless network which is connected in advance;

step S140: and after the Bluetooth connection initiated by the application program passes the authentication, confirming that the Bluetooth connection initiated by the application program is safe connection, and establishing the Bluetooth connection between the user equipment and the vehicle-mounted equipment.
The following describes steps S110 to S140 of the bluetooth automatic connection method according to this embodiment in detail.
Step S110: when a Bluetooth demand signal sent by an application program is detected, bluetooth connection is started and whether the Bluetooth connection is the first connection or not is judged.
Specifically, in this embodiment, the ue 10 detects a bluetooth request signal sent by the application, starts a bluetooth connection, scans connectable bluetooth signals, detects bluetooth signal strength of the connectable bluetooth signals, and determines whether the bluetooth connection is a first connection when the detected bluetooth signal strength is within a predetermined signal strength range: judging whether the connection information of the vehicle-mounted device 20 corresponding to the connectable Bluetooth signal exists in the Bluetooth connection list, namely determining whether the vehicle-mounted device 20 corresponding to the connectable Bluetooth signal establishes Bluetooth connection with the user equipment 10, if not, determining that the Bluetooth connection is the first connection, and if so, determining that the Bluetooth connection is not the first connection.
Step S120: when the bluetooth connection is the first connection, the authentication code is acquired from the in-vehicle device 20 through the non-bluetooth wireless network in which the connection is established in advance.
In this embodiment, the user equipment 10 and the vehicle-mounted device 20 establish a non-bluetooth wireless network such as wifi, GPRS,2/3/4/5G wireless network in advance.
The vehicle-mounted device 20 stores an authentication code of the user device 10 in advance, wherein the authentication code of the user device 10 is an authentication code provided by a manufacturer of the user device 10 and dedicated to the user device 10. The authentication code of the user equipment 10 is stored in the vehicle-mounted equipment 20 in advance, and when the user equipment 10 requests to establish Bluetooth communication with the vehicle-mounted equipment 20, the authentication code, which is exclusive to the user equipment 10, in the vehicle-mounted equipment 20 is sent to the user equipment 10 through non-Bluetooth wireless networks such as wifi, GPRS,2/3/4/5G wireless networks and the like which are established in advance with the vehicle-mounted equipment 20.
In this embodiment, the authentication code dedicated to the user equipment 10 may be directly stored in the vehicle-mounted device 20, or may be stored in a cloud server of the vehicle-mounted device 20, and when the user equipment 10 requests to establish bluetooth communication with the vehicle-mounted device 20, the vehicle-mounted device 20 downloads and obtains the corresponding authentication code from the cloud server.
Step S130: and authenticating the Bluetooth connection initiated by the application program based on the authentication code.
Specifically, in this embodiment, as shown in fig. 3, the authenticating the bluetooth connection initiated by the application based on the authentication code includes:
step S131: matching the acquired authentication code with a local authentication code pre-stored in the user equipment 10;
step S132: when the authentication code matches with a local authentication code pre-stored in the user equipment 10, authenticating the application program as a trusted application program;
step S133: and after the application program is authenticated to be a trusted application program, determining that the Bluetooth connection initiated by the application program is a safe connection.
In this embodiment, the authentication code obtained from the vehicle-mounted device 20 is compared with the local authentication code of the user device 10, and it is determined that the application program initiating the bluetooth connection is a safe and trusted application program, so as to confirm that the bluetooth connection initiated by the application program is a safe connection.
Step S140: after the bluetooth connection initiated by the application program passes the authentication, the bluetooth connection initiated by the application program is confirmed to be a safe connection, and the bluetooth connection between the user equipment 10 and the vehicle-mounted equipment 20 is established.
In this embodiment, the application program that sends the bluetooth requirement signal is authenticated as a trusted application program through the authentication code, and a trust relationship of a higher level of bluetooth connection is established, so that automatic authentication without user access confirmation when bluetooth connection is established for the first time is realized.
In addition, in this embodiment, the bluetooth automatic connection method further includes: prompting the user equipment 10 to establish connection with the vehicle-mounted equipment 20 in response to the connection between the user equipment 10 and the vehicle-mounted equipment 20; wherein, the prompting mode comprises the following steps: controlling one or more combinations of the user equipment 10 to light a screen, pop-up a window, and voice prompts.
For example, after the user equipment 10 establishes the connection with the vehicle-mounted device 20, the user equipment 10 is prompted to establish the connection with the vehicle-mounted device 20 by controlling the user equipment 10 to be lightened. For example, when the car machine and the mobile phone are successfully connected through Bluetooth, the mobile phone is triggered to lock the screen to display and light the screen.
For another example, after the user device 10 establishes a connection with the in-vehicle device 20, a pop-up window presentation may be performed by popping up an information frame under the lock screen of the user device 10. For example, when the car machine and the mobile phone are successfully connected by bluetooth, pop up on the mobile phone screen: "Bluetooth connection established".
After the user device 10 establishes a connection with the in-vehicle device 20, the prompt may be provided by voice or vibration sound. For example, when the bluetooth link between the car machine and the mobile phone is successful, the mobile phone plays: "bluetooth connection established".
Therefore, in the bluetooth automatic connection method of the embodiment, when the bluetooth connection is first established between the user equipment 10 and the vehicle-mounted device 20, the authentication is automatically performed, so as to achieve the effect of non-inductive authentication, and effectively improve the user experience.
In the present embodiment, the audio signal is transmitted to the vehicle-mounted device 20 through the established bluetooth connection, and the video signal is transmitted to the vehicle-mounted device 20 through the non-bluetooth wireless network.
In this embodiment, as shown in fig. 4, the application program of the user equipment 10 is a screen projection application program, and when the video stream of the user equipment 10 is projected into the vehicle-mounted device 20, the audio signal is transmitted through a bluetooth network, and the video signal is transmitted through a non-bluetooth wireless network such as wifi. After the user equipment 10 and the vehicle-mounted equipment 20 are connected through wifi and when the bluetooth connection needs to be established, the bluetooth connection between the user equipment 10 and the vehicle-mounted equipment 20 is automatically established through the bluetooth automatic connection method of the embodiment, then an audio signal is transmitted to the vehicle-mounted equipment 20 through the established bluetooth connection, and a video signal is transmitted to the vehicle-mounted equipment 20 through the non-bluetooth wireless network.
Fig. 5 is a schematic flowchart of the bluetooth automatic connection method applied to the vehicle-mounted device 20 in this embodiment, and as shown in fig. 5, the bluetooth automatic connection method applied to the vehicle-mounted device 20 includes the following steps:
in step S210, when a bluetooth request signal sent by an application program projected by the user equipment 10 in the vehicle-mounted device 20 is detected, a pre-stored authentication code of the user equipment 10 is acquired.
The vehicle-mounted device 20 prestores the authentication code of the user device 10, or the vehicle-mounted device 20 acquires the authentication code of the user device 10 prestored in the cloud server from the cloud server.
Step S220, sending the authentication code to the user equipment 10, so that the user equipment 10 authenticates the bluetooth connection.
Step S230, after the user equipment 10 passes the bluetooth connection authentication, establishing a connection with the user equipment 10.
That is to say, in this embodiment, when the application initiating the bluetooth connection needs to be authenticated, the authentication code (authentication code) may be obtained from the in-vehicle device 20 or the cloud server, and the application is authenticated as a safe application, and the user device 10 may authenticate the bluetooth connection initiated by the application as a safe connection, which is not a connection initiated by a third-party application, and may perform quick authentication.
