detailed description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While the embodiments of the present invention have been shown in the drawings, the embodiments Rather, these embodiments are provided so that this disclosure will be more fully understood and the scope of the disclosure will be fully disclosed.

An embodiment of the present invention provides a Bluetooth connection method. As shown in FIG. 1 , a Bluetooth connection method according to an embodiment of the present invention includes:

Step S102: The master device receives at least one Bluetooth broadcast information that is sent by the slave device and includes identity identification information.

Step S104, determining whether the identity identification information included in the Bluetooth broadcast information matches the identity identification information that the primary device needs to identify;

Step S106, if yes, establish a Bluetooth connection with the slave device.

According to the Bluetooth connection method provided by the embodiment of the present invention, after receiving the Bluetooth broadcast information sent by the slave device, the master device parses and determines whether the identity identifier information included in the Bluetooth broadcast information matches the identity identifier information that the master device needs to identify. If it matches, the master will actively establish a Bluetooth connection with the slave. The Bluetooth connection method provided by the embodiment of the invention has a simple process and effectively solves the problem that the traditional interconnection between devices is complicated. According to the Bluetooth connection method provided by the embodiment of the present invention, when a Bluetooth connection is established between the master device and the slave device, the user does not need to participate, and the identification and matching of the identity information is automatically performed, thereby simplifying the connection step and saving the connection time. In particular, when there are many master devices and slave devices, the Bluetooth connection method provided according to the present invention can quickly identify the master device and the slave device that need to be matched and establish a Bluetooth connection.

In general, the first Bluetooth connection between the primary device and the device needs to be accurately identified. Another embodiment of the present invention provides a Bluetooth connection method, which is applicable to a first time establishing a Bluetooth connection between a master device and a slave device. As shown in FIG. 2, the Bluetooth connection method according to another embodiment of the present invention includes:

Step S202: The primary device receives, for the first time, at least one Bluetooth broadcast information that is sent by the secondary device and includes identity identification information.

Step S204, determining whether the preset first identity identification information is included in the Bluetooth broadcast information;

Step S206, if yes, establishing a Bluetooth connection with the slave device for the first time.

According to the Bluetooth connection method provided by the embodiment, when the master device and the slave device establish a Bluetooth connection for the first time, the first identity identification information may be defined in advance in the Bluetooth broadcast information of the slave device, and when the master device receives the Bluetooth broadcast information sent by the slave device, After the parsing is performed, if it is determined that the Bluetooth broadcast information includes the preset first identity information, the Bluetooth connection is actively established with the slave device. In the Bluetooth connection method provided by the embodiment of the present invention, the user connection is also unnecessary, and the connection process is simple and effective. The master device can accurately identify the slave devices that need to be connected in multiple slave devices, and quickly establish a Bluetooth connection.

The first identity information preset in the Bluetooth broadcast information of the slave device may be a 6-byte character string, and preferably 6 bytes of data are all 0s. Of course, the first identity information may also be a string of other lengths, which is not limited by the present invention.

In order to establish a Bluetooth connection relationship between the master device and the slave device, the slave device may further receive and record the second identity information sent by the master device after the step S206. Preferably, the slave device can save the second identity information of the master device it receives to the flash memory.

Flash memory is a kind of non-volatile memory that can maintain data for a long time without current supply. Its storage characteristics are equivalent to hard disks. This feature is the storage medium for flash memory of various portable digital devices. basis. Therefore, saving the second identity information of the master device to the flash can prevent the loss of information and be effectively stored.

When the slave device sends the Bluetooth broadcast information again, the slave device may send the Bluetooth broadcast information including the second identity information to the master device identification. If the master device successfully identifies, the master device may respond to the Bluetooth connection request of the master device and the master device. The device establishes a Bluetooth connection.

Preferably, the second identity information sent by the master device is a MAC (Media Access Control or Medium Access Control) address of the master device, and is translated into media access control, or a physical address and a hardware address, and is used to represent each of the Internet. The identifier of the site, expressed in hexadecimal notation, for a total of six bytes (48 bits). The first three bytes are codes assigned by the RA (Registration Authority) of the IEEE (Institute of Electrical and Electronics Engineers) to different manufacturers (high 24 bits), also known as "Organizationally Unique Identifier", the last three bytes (lower 24 bits) can be assigned to the production adapter interface, called the extension identifier (uniqueness). An address block can generate 224 different addresses. Therefore, it is very convenient to use the unique MAC address of the master device as its second identity information.

The device can be equipped with a BLE (Bluetooth Low Energy) chip, which is a low-cost, short-distance, interoperable and robust wireless technology that operates in the license-free 2.4 GHz ISM radio frequency band. It was designed from the outset as ultra-low-power (ULP) wireless technology. It uses many intelligent means to minimize power consumption. Bluetooth low energy technology uses a variable connection time interval, which can be set from a few milliseconds to a few seconds depending on the application. In addition, because BLE technology uses a very fast connection method, it can usually be in a "non-connected" state (saving energy). At this time, both ends of the link only know each other, and only when necessary, the link is opened and then exhausted. It is possible to close the link in a short time. The broadcast information of the BLE chip can carry the customized information content. Therefore, the preset first identity information and the second identity information of the master device can be added to the Bluetooth broadcast information, when the slave device receives the slave device. When the Bluetooth broadcast information is sent, the preset first identity information or the second identity information representing the master device is analyzed, and then the slave device is connected.

In the implementation process, the above Bluetooth connection method is particularly applicable to the sitting posture correction lamp and the corresponding wearing device, wherein the sitting posture correction lamp can be used as the main device, and the wear device can be used as the slave device, when the user uses the sitting posture correction table lamp, there is no need to manually Sitting posture correction table lamp and wearing device for manually starting Bluetooth to search and match, just wear wearing equipment, sitting posture correction table lamp and wearing device can quickly establish Bluetooth connection, and then sitting posture correction table lamp for sitting posture correction, easy to use, user experience effect it is good.
