Referring to FIG. 2, FIG. 2 is a schematic flowchart of a first embodiment of a method for pairing a Bluetooth device according to the present application.

In this embodiment, the pairing method for a Bluetooth device is applied to a pairing device for a Bluetooth device. The pairing device includes a Bluetooth headset, a Bluetooth headset box, and a terminal to be paired. The pairing method for the Bluetooth device includes the following steps:

Step S10, when the short-range wireless communication NFC connection instruction is detected, the Bluetooth headset box obtains the terminal Bluetooth device address of the terminal to be paired through the NFC connection with the terminal to be paired, and sends the terminal to the terminal. The Bluetooth device address is sent to the Bluetooth headset;

Currently, pairing between Bluetooth devices requires the user to open the Bluetooth configuration interface of the Bluetooth device, scan for paired Bluetooth devices, and manually select a corresponding Bluetooth device from multiple Bluetooth device connection lists for pairing. Not only the Bluetooth pairing efficiency is low, but also the Bluetooth pairing operation is cumbersome. In order to solve the above problems, in this embodiment, through the short-range wireless communication NFC connection between the Bluetooth headset box and the terminal to be paired, a quick handshake is realized, the address data of the Bluetooth device is exchanged, and the user does not need to manually perform a Bluetooth search. The fast Bluetooth pairing between the terminals to be paired simplifies the Bluetooth pairing operation and improves the Bluetooth pairing efficiency. Specifically, the user can connect the two Bluetooth devices by NFC by contacting the Bluetooth earphone box to be paired with the designated position of the terminal to be paired. The terminal to be paired may be a TV, a mobile phone to be connected, a computer, or an IPAD and other Bluetooth devices with an NFC module. When the NFC connection command is detected, it is detected that the two Bluetooth devices are in effective contact. Based on the NFC connection command, the Bluetooth headset box can quickly shake hands with the terminal to be paired and exchange Bluetooth address information, that is, the Bluetooth headset The box obtains the terminal Bluetooth device address of the terminal to be paired, and sends the terminal Bluetooth device address to the Bluetooth headset.

Step S20, the terminal to be paired is connected through the NFC to obtain the Bluetooth device address of the headset pre-stored in the Bluetooth headset box;

In this embodiment, the terminal to be paired may acquire the Bluetooth device address of the headset pre-stored in the Bluetooth headset box based on the NFC connection with the Bluetooth headset box. Wherein, when the bluetooth earphones are placed in the box, the bluetooth device addresses of the earphones of the two Laner earphones can be obtained and stored through a wired connection (shrapnel connection) with the bluetooth earphones. It can also be that when the bluetooth earphone box leaves the factory, the bluetooth device address of the earphone of the bluetooth earphone is directly written into the storage unit of the bluetooth earphone box.

Step S30: According to the terminal Bluetooth device address and the headset Bluetooth device address, the Bluetooth headset and the terminal to be paired complete a Bluetooth pairing connection.

In this embodiment, the Bluetooth headset and the terminal to be paired may search for a Bluetooth device to be paired within a preset range at a preset frequency, and generate a Bluetooth device set according to the to-be-paired Bluetooth device. Wherein, the Bluetooth device set includes at least one Bluetooth device. Then the bluetooth headset and the terminal to be paired can compare the terminal bluetooth device address and the bluetooth device address of the earphone respectively with the bluetooth device addresses in the set of bluetooth devices searched by each other, so as to determine the target bluetooth device and complete the bluetooth pairing connection. .

Wherein, the step S30 specifically includes:

In this embodiment, the to-be-paired terminal searches for a Bluetooth device to be paired within a preset range, and acquires a Bluetooth device information set of the to-be-paired Bluetooth device. Then, the terminal to be paired compares and matches the headset Bluetooth device address with the Bluetooth device information set, and determines whether the headset Bluetooth device address exists in the Bluetooth device information set. That is, when the Bluetooth device address of the headset exists in the Bluetooth device information set, the Bluetooth device address of the headset to be paired is determined from among the plurality of Bluetooth devices searched. In a specific embodiment, the Bluetooth device address of the Bluetooth headset, that is, the Bluetooth name and the Bluetooth address, can also be sent to the terminal to be paired through the NFC connection, and the terminal to be paired can be controlled according to the Bluetooth name and Bluetooth address of the Bluetooth headset. Search to determine the Bluetooth device address of the headset to be connected. Synchronously or asynchronously, the terminal to be paired feeds back the instruction to complete the Bluetooth device address of the headset to the Bluetooth headset box through the NFC connection, that is, synchronously control the Bluetooth headset (or the Bluetooth headset box) or asynchronously control the Bluetooth headset to broadcast the headset Bluetooth device address, that is, Bluetooth name and Bluetooth address. Thereby, a Bluetooth pairing instruction between devices is triggered, so that the terminal to be paired can determine whether the searched Bluetooth device address of the headset is the information of the Bluetooth headset to be paired based on the Bluetooth device address of the headset broadcast by the Bluetooth headset. In a specific embodiment, when the user needs to perform Bluetooth pairing and connection between the Bluetooth headset device and the terminal to be paired, the Bluetooth headset can be placed in the pairing position corresponding to the terminal to be paired. The position distance between the terminal to be paired and the Bluetooth headset is detected by the infrared sensor, and the contact state is confirmed. In order to facilitate the user to connect to the current wired connection state, when it is detected that the contact state between the terminal to be paired and the Bluetooth headset is abnormal, the indicator light connected to the terminal to be paired or the Bluetooth headset flashes red to remind the user. When it is detected that the contact state between the terminal to be paired and the Bluetooth headset is normal, the green light will be on. Then, the terminal to be paired is controlled to send a connection status check data packet to the Bluetooth headset by means of NFC connection to detect the connection status of the NFC data line. If the terminal to be paired receives a corresponding feedback command from the Bluetooth headset, it confirms that the NFC connection between the terminal to be paired and the Bluetooth headset is normal, and the long green light reminds the user that the connection is normal, otherwise the long red light reminds the user that the connection is abnormal. And when the connection is normal, the Bluetooth address and device name of the Bluetooth headset are sent to the terminal to be paired. And when it is detected that the terminal to be paired receives a bluetooth headset reply command, based on the bluetooth device information of the bluetooth headset, the terminal to be paired is controlled to search for bluetooth device information, and the bluetooth headset is controlled to start broadcasting its own headset bluetooth device address. The terminal to be paired is controlled to produce a Bluetooth device list according to the searched target Bluetooth device information (the Bluetooth device list may include one or more Bluetooth device information). Match the list of bluetooth devices with the bluetooth address and bluetooth name sent by the bluetooth headset. When there is a bluetooth device in the bluetooth device list that has the same address as the bluetooth device of the headset, that is, when it is determined that the matching is consistent, automatic bluetooth pairing between the terminal to be paired and the bluetooth headset is realized, and a long green light is displayed to remind the user that the pairing is successful. When the pairing fails, a long red light is displayed to remind the user that the Bluetooth pairing fails. According to the preset time interval, the terminal to be paired can be controlled to search for Bluetooth device information again, and the Bluetooth automatic pairing operation can be performed again until the Bluetooth pairing operation is completed.

This embodiment provides a method for pairing a Bluetooth device. The method for pairing a Bluetooth device is applied to a pairing device for a Bluetooth device. The pairing device includes a Bluetooth headset, a Bluetooth headset box, and a terminal to be paired. When communicating the NFC connection command, the Bluetooth headset box obtains the terminal Bluetooth device address of the terminal to be paired through the NFC connection with the terminal to be paired, and sends the terminal Bluetooth device address to the Bluetooth headset The terminal to be paired is connected through the NFC to obtain the Bluetooth device address of the headset pre-stored in the Bluetooth headset box; according to the Bluetooth device address of the terminal and the Bluetooth device address of the headset, the Bluetooth headset and the terminal to be paired are completed Bluetooth pairing connection. In the above-mentioned manner, the present application performs NFC connection with the terminal to be paired through the Bluetooth headset box, realizes a quick handshake, exchanges the address data of the Bluetooth device, and does not require the user to manually perform a Bluetooth search, and realizes fast Bluetooth pairing between the Bluetooth headset and the terminal to be paired, The bluetooth pairing operation is simplified, the bluetooth pairing efficiency is improved, and the technical problems of low pairing efficiency of the bluetooth pairing method of the existing bluetooth device and high complexity of the bluetooth pairing operation are solved.

Step S70, when the Bluetooth headset box receives the verification data packet, it sends the NFC connection instruction to the terminal to be paired.

Wherein, the step S70 specifically includes:

In order to ensure the effective connection of the NFC connection, this embodiment uses an infrared proximity sensor to determine whether the terminal to be paired is in effective contact with the Bluetooth headset (that is, the NFC module of the terminal to be paired is in correct contact with the NFC module of the Bluetooth headset), thereby judging whether the terminal to be paired is in correct contact with the NFC module of the Bluetooth headset Whether a valid connection is established with the Bluetooth headset. Specifically, the device distance between the terminal to be paired and the Bluetooth headset is obtained through an infrared proximity sensor, so as to determine whether the terminal to be paired and the Bluetooth headset are in a contact state according to the device distance, that is, to determine whether the device distance is less than a preset threshold, such as a device If the distance is equal to 0, it is judged as a contact state. When it is determined that the terminal to be paired and the Bluetooth headset are in a contact state, the terminal to be paired is controlled to send an NFC connection detection instruction, such as a connection status detection data packet, to the Bluetooth headset to determine whether the terminal to be paired and the Bluetooth headset successfully establish an NFC connection. That is, the terminal to be paired sends a connection status check data packet to the Bluetooth headset through the NFC connection, so as to detect the connection status of the current NFC connection. When the terminal to be paired receives a reply from the Bluetooth headset, it confirms that the connection is normal, that is, if the Bluetooth headset receives the connection status detection data packet, and based on the connection status detection packet, it feeds back the corresponding connectable instruction to the terminal to be paired , if the data packet is verified, it means that the terminal to be paired and the Bluetooth headset have successfully established an NFC connection, that is, the terminal to be paired and the Bluetooth headset are in effective contact. An NFC connection instruction is generated so that the terminal to be paired communicates with the Bluetooth headset based on the NFC connection, thereby sending the Bluetooth device address of the Bluetooth headset to the terminal to be paired through the NFC connection. If the Bluetooth headset does not feed back the corresponding verification data packet based on the connection status detection data packet sent by the terminal to be paired, or if the data packet fed back by the Bluetooth headset is not the verification data packet corresponding to the connection status detection data packet, it is determined to be pending. If the contact state between the paired terminal and the Bluetooth headset is not in valid contact, it means that the current contact state between the terminal to be paired and the Bluetooth headset is not the correct contact position, and a device adjustment reminder message is generated and displayed to remind the user to adjust the relative position of the Bluetooth device to be paired, so that the Contact the NFC module of the terminal to be paired with the NFC module of the Bluetooth headset.
