Fig. 1 is a flow chart illustrating a method for communication of a bluetooth device according to an embodiment of the disclosure, where the bluetooth device includes a master device and a slave device, and the method is applied to the master device, as shown in fig. 1, and the method includes:
S101, under the condition that a broadcast data packet sent by the slave device is scanned, extracting device information in the broadcast data packet;
Specifically, the type of slave device that needs to be scanned and the type of protocol that broadcasts the data packet may be determined. The scan types include active scan and passive scan, etc., and the scan modes include a whitelist scan mode, and in some embodiments, a frequency range of scan, a duration of scan, or a packet number limit, etc. may also be set.
Illustratively, in the disclosed embodiments, the master device turns on a white list scanning mode to scan, the white list being a predefined set of slave device addresses or specific identifiers that are considered trusted or authorized. By allowing only known and trusted devices to connect, the risk of suffering man-in-the-middle attacks or other security threats can be reduced, unnecessary communication attempts can be reduced by omitting devices not on the white list, communication efficiency can be improved, time and resource consumption for processing irrelevant devices can be reduced, and system performance can be improved.
S102, based on the device information, updating a Bluetooth device address of the main device;
in particular, a pairing list of the master device is obtained, and the pairing record refers to information stored on the master device when paired with the slave devices, wherein the information allows the master device to be reconnected to the slave devices without the need for a complete pairing process to be performed again. The pairing record may include the MAC address of the device, pairing password, trust information, etc. In particular, some devices may have dedicated bluetooth management software through which the pairing records can be viewed, and for the developer, the pairing records can be accessed using an API or command line tool provided by the operating system. For example, at Androi d, a list of paired devices may be obtained using class B l uetoothAdapter.
And under the condition that the equipment information of the slave equipment is recorded in the pairing list, acquiring a pairing key corresponding to the slave equipment, and acquiring a Bluetooth equipment address currently used by the master equipment.

The acquisition of the pairing key typically involves a security protocol such as a pairing algorithm, which may include entering a PI N code or other authentication information using the device. In some embodiments, the pairing key may be stored in a pairing record of the master device, but for security reasons, keys are typically stored in encrypted form. The bluetooth device address is the MAC address of the device for uniquely identifying the device in the bluetooth network. The bluetooth device address that the master device is currently using may be obtained through bluetooth settings of the operating system or queried using a development tool.

It can be understood that if the slave device determines that the address from which the target data request is initiated is incorrect, the target data packet is not returned, and the master device cannot obtain the data of the slave device, so that the communication security of the bluetooth device is ensured.
S104, receiving and analyzing the target data packet.
Specifically, the master device parses the target data packet, and extracts required target data, such as an address, a name, and the like of the slave device. Furthermore, the master device can determine whether to establish connection with the slave device according to the target data, so that bidirectional data interaction is realized.

And the master device only needs to receive the broadcast data packet sent by the slave device, can communicate without establishing connection with the slave device, and meanwhile, a random back-off mechanism is also canceled, so that the power consumption generated by connection establishment and response waiting is reduced.

Information exchange is carried out with the slave equipment, the pairing key is generated according to the exchanged information and a preset pairing algorithm, and the exchanged information comprises random numbers generated by the master equipment and the slave equipment;
and storing the device information of the slave device and the pairing key into the pairing list.
Pairing operation refers to the process of exchanging necessary information between two devices to establish a connection and communication. Some security steps are typically involved, such as entering a pairing code or using a security protocol in bluetooth technology. The user can know and manage the connected devices through the pairing process, so that the connected devices are convenient to maintain and update.

responding to a target data request sent by a master device, acquiring a pairing key and a Bluetooth device address of the master device, wherein the pairing key is generated by pairing operation between the slave device and the master device, and the master device and the slave device share the pairing key;
and under the condition that the master device is judged to be the paired master device according to the pairing key and the Bluetooth device address of the master device, replying a target data packet to the master device so that the master device receives and analyzes the target data packet.
Specifically, the slave device may calculate the pairing key according to a preset rule to obtain a target response address;
And under the condition that the target response address is consistent with the Bluetooth device address of the master device, judging that the master device is the paired master device.

For example, the slave device enters a shutdown mode to sleep after pairing with the master device is completed, until a user triggers to start a broadcast communication mode through an external key, and only when the slave device needs to communicate with the master device or other devices, the slave device wakes up and starts the broadcast mode. The unnecessary communication is reduced by waking up according to the requirement, and the energy efficiency is further improved;
after the reply of the target data packet to the master device, the method further includes:
the slave device enters a second sleep mode, and the slave device enters an energy-saving state in the second sleep mode, so that unnecessary energy consumption can be reduced;
