The term 2: BLE;
BLE, Bluetooth Low Energy, is an important branch of the Bluetooth family, and was originally proposed in Bluetooth 4.0. BLE is more focused on maximizing the standby time and connection response speed of the device than classical bluetooth (bluetooth 3.0 and before), so it finds wide application in smart devices that are sensitive to power consumption.

The term 6: inquiry;
a classic bluetooth device will be in the inquirycan state when it wants to be discovered by other devices. Inquiry is sent when other devices want to discover a classic bluetooth device. When the classic bluetooth device in the inquiry state receives inquiry, it replies to the corresponding packet indicating its presence. The other device then discovers itself. Generally, the device is in the acquryscan state for a period of time after the bluetooth switch is turned on, but once the discoverable time elapses, the device automatically exits the acquryscan state, so that other devices cannot discover themselves through normal means.
The term 7: page;
a classic bluetooth device will be in pagescan state when it is allowed to be connected by other devices. When other devices want to connect to a classic bluetooth device, a page is sent. When the classic bluetooth device in the pagescan state receives the page, the classic bluetooth device replies a corresponding data packet to indicate whether the classic bluetooth device accepts the connection. The device will normally be in pagescan state as long as it turns on the bluetooth switch.
The term 8: 2.4GHz wireless frequency band;
a large number of open source short-distance wireless transmission technologies exist in a 2.4GHz wireless frequency band, and the wireless frequency band is widely and universally used all over the world.

The term 11: BD _ ADDR;
i.e. Bluetooth device address
Referring to fig. 1, fig. 1 is a flowchart of a typical bluetooth device detection method according to an embodiment of the present disclosure. The method comprises the following steps:
s101: acquiring a data packet from a target channel; the target channel is a data transmission channel of the low-power Bluetooth device.
The target channel is a data transmission channel of the low power consumption bluetooth device, namely an inverting physical channel, specifically, part or all of three signals numbered 37, 38, and 39. Because the target channel is a data transmission channel of the low-power-consumption Bluetooth device, the data packet acquired through the target channel is the data packet sent by the low-power-consumption Bluetooth device. Since bluetooth low energy and classic bluetooth are usually integrated on one chip, in some cases, the bluetooth low energy device will use the same device address as the classic bluetooth device, i.e. the device address of the classic bluetooth device is used as the public address of the bluetooth low energy device. The data packet can be retrieved from the target channel for performing the subsequent steps. The embodiment does not limit the specific obtaining manner of obtaining the data packet, and reference may be made to the related art. The data packet can be any form of data packet with any content sent by any bluetooth low energy device as long as the data packet conforms to the protocol specification of the bluetooth low energy device.
S102: and analyzing the data packet to obtain a public address.
After the data packet is obtained, the data packet is analyzed so as to obtain a public address. It should be noted that the specific parsing method corresponds to the data packet, and the parsing method for the data packet is different according to the protocol specification of the data packet. The public address is a field in the data packet, and the specific form thereof is not limited.
Further, in a possible implementation manner, in order to accurately acquire the public address, it is avoided that the classic bluetooth device cannot be detected due to the acquisition of the wrong public address; or when the public address does not exist in the data packet, the subsequent operation is executed, which causes the waste of computing resources. The S102 step may include:
step 11: and analyzing the data packet according to the protocol specification corresponding to the low-power-consumption Bluetooth equipment to obtain an analysis field.
Step 12: it is determined whether a public address is present in the resolution field,
step 13: if so, the public address is obtained.
After the data packet is obtained, the data packet is analyzed according to the protocol specification corresponding to the low-power-consumption Bluetooth device, so that an analyzed field which is analyzed correctly is obtained, and the situation that an incorrect public address is obtained due to the fact that the data packet is analyzed incorrectly is avoided, and further the classic Bluetooth device cannot be detected. After the analysis field is obtained, whether a public address exists is judged. It should be noted that, in some cases, a public address does not exist in all data packets, and therefore, before obtaining the public address, it is necessary to determine whether the public address exists first, so as to prevent other information (for example, a random address) from being mistaken as the public address, and further perform a subsequent operation using the wrong public address. Due to the error of the public address, the corresponding classic bluetooth device cannot be detected necessarily, and the waste of computing resources is caused. The present embodiment does not limit the operation performed when the public address does not exist, and for example, the operation may be a no operation, that is, no operation is performed; or may continue to acquire data packets from the target channel.
S103: and (4) performing a classic Bluetooth device connection attempt by using the public address, and obtaining a corresponding connection result.
After the public address is obtained, a classic bluetooth device connection attempt is made using the public address, i.e. the public address is used as the device address of the hypothetical classic bluetooth device, with which the connection is made with the hypothetical classic bluetooth device. It should be noted that, since it is not determined whether the public address is actually the device address of a certain classic bluetooth device, it is determined as the device address of the "hypothetical classic bluetooth device". The "imaginary classic bluetooth device" may or may not exist, i.e. the classic bluetooth device having the public address as the device address may or may not exist. After the classic bluetooth device connection attempt is performed by using the public address, a connection result can be obtained according to the actual connection condition, and the connection result indicates whether the connection is successfully established with the classic bluetooth device corresponding to the public address.
Further, in one possible implementation, since a classic bluetooth device is always in a pagescan state after being turned on, a connection attempt can be made using a page operation. The S103 step may include:
step 21: and performing page operation by using the public address.
Step 22: and judging whether a bottom layer connection is established between the public address and the public address.
Step 23: if so, the connection result is successful.
Step 24: if not, the connection result is failure.
The specific process and manner of page operation are not limited, and reference may be made to related technologies, which are not described herein in detail in this embodiment. After the page operation is performed, if the public address is determined to be the device address of a certain classic bluetooth device, the underlying connection can be established with the classic bluetooth device. If the public address is not the device address of any classic bluetooth device, or the corresponding classic bluetooth device is not connectable, the corresponding underlying connection cannot be established. And judging whether bottom layer connection is established between the Bluetooth device and the public address, if so, determining that the connection result is successful, namely determining that connection is established with one connectable classical Bluetooth device, and the connection attempt is successful, so that the corresponding connection result is successful. And if the bottom layer connection is not established, determining that the connection result is failure.
Further, the connection embodiment of which layer the bottom layer connection is specifically is not limited, and may be set according to actual conditions. For example, in one possible embodiment, the underlying connection is a link layer connection, and thus step 22 may include:
step 31: it is determined whether a link layer connection is established with the public address.
Step 32: and if the link layer connection is established, determining that the bottom layer connection is established.
Step 33: and if the link layer connection is not established, determining that the bottom layer connection is not established.
The present embodiment does not limit the specific determination manner of whether the link layer connection is established, and reference may be made to related technologies, which is not described herein again.
S104: and if the connection result is successful, determining that the classic Bluetooth device is detected.
If the connection result is successful, the classic Bluetooth device is determined to be detected. The public address obtained from the data packet does correspond to a classic bluetooth device integrated on the same chip as the sender of the data packet, i.e. the bluetooth low energy device sending the data packet. After determining that a classic bluetooth device is detected, may further include:
the public address is determined to be the device address of the classic bluetooth device and the device address is recorded.
The device address of the classic bluetooth device is recorded, and the detected classic bluetooth device can be tested subsequently by using the device address.
Further, in a possible implementation manner, when the classic bluetooth device is detected by using the public address, the classic bluetooth device may be scanned to determine whether the classic bluetooth device in the discoverable state exists, and the classic bluetooth device in the discoverable state is necessarily connectable. The method can also comprise the following steps:
step 41: and scanning the classic Bluetooth device to judge whether the classic Bluetooth device in the discoverable state exists.
Step 42: if so, it is determined that a classic Bluetooth device is detected.
The discoverable state is the inquirycan state. The execution timing of step 41 and step 42 is not limited. For example, the steps may be executed in parallel as in steps S101 to S104, or may be executed after the step S104 is executed or when the connection result is not successful.
After finishing detecting classic bluetooth equipment, can also carry out bluetooth penetration test to the classic bluetooth equipment that detects. The specific test procedure and mode of the bluetooth penetration test are not limited in this embodiment.
By applying the classic bluetooth device detection method provided by the embodiment of the application, the data packet is obtained through the target channel, and the target channel is the data transmission channel of the low-power-consumption bluetooth device, so that the obtained data packet is the data packet sent by the low-power-consumption bluetooth device. Bluetooth low energy and classic bluetooth are usually integrated in one chip, so they may use the same device address, i.e. bluetooth low energy may use the device address of the classic bluetooth device as their own public address. After the data packet is analyzed to obtain a public address, classic Bluetooth equipment connection attempt is carried out by using the public address, and connection to a certain classic Bluetooth address by using the public address is attempted to obtain a corresponding connection result. If the connection is successful, the device address indicating that the public address is indeed a classic bluetooth address can be determined to detect classic bluetooth devices. It is possible to acquire a device address, i.e., a common address, of a classic bluetooth device corresponding to a bluetooth low energy device through a packet of the bluetooth low energy device acquired using a side channel, i.e., a target channel. A connection attempt may then be made using the public address and if successful, a classic bluetooth device is determined to have been detected. Still can detect the classic bluetooth equipment that can connect after being hidden, can carry out comprehensive detection to classic bluetooth equipment, solved the incomprehensive problem of classic bluetooth equipment detection.
In the following, the classic bluetooth device detection device provided in the embodiment of the present application is introduced, and the classic bluetooth device detection device described below and the classic bluetooth device detection method described above may be referred to correspondingly.
In one embodiment, a classic bluetooth device detection device includes a memory and a processor, the memory for storing a computer program; a processor for executing a computer program to implement the classic bluetooth device detection method described above.
Optionally, the classic bluetooth device detection device may further include 3 micro bit development boards, and each micro bit development board corresponds to a target channel with a different serial number. Referring to fig. 2, fig. 2 is a schematic diagram of a working flow of a classic bluetooth device according to an embodiment of the present application. The bit development board sniffs signals 37, 38 and 39 respectively, and receives a data packet sent by the low-power Bluetooth device, namely a BLU Adv PDU (BLU advertising physical channel PDU). After receiving the data packet, the data packet is sent to the Host through the port, and the Host may be the processor. The processor analyzes the PDU and judges whether a public address exists or not, if not, the PDU is received again, if so, the public address is sent to a BR/EDR controller (namely a classic Bluetooth controller) through a port so as to carry out page operation, detect possible classic Bluetooth equipment and obtain a page result, namely a connection result. And the Host acquires the page result through the port and judges whether the page operation on the public address is successful or not. If the PDU is successfully acquired, the classic Bluetooth device is determined to be found, the PDU is continuously acquired, and if the PDU is not successfully acquired again.
The specific implementation steps are as follows:
1. first, 3 micro bits are configured, and the working channels are set to 37, 38 and 39 respectively. The three channels cover all channels on which BLE transmits the advertising physical channel PDU. The micro bit development board is then set to the acquisition only mode.
And 2.3 micro blocks, bit, are used for asynchronously transmitting the received data packet to the Host.
And 3, after receiving the data packet transmitted by the micro, analyzing each field of the data packet according to the BLE protocol specification by the Host, and judging whether the current data packet contains a public address (public address) of the BLE equipment. If a public address is found, it is transmitted to the BR/EDR controller, i.e. the classic Bluetooth controller. And if the public address is not found, the data packet transmitted by the micro bit development board is continuously received.
And 4, after receiving the public address, the BR/EDR controller directly takes the public address as the address of the classic Bluetooth device, tries to establish connection with the address through page, and returns the connection result to Host.
And 5, after receiving the connection result returned by the BR/EDR controller, judging whether the connection is successful or not by the Host. If the connection is successful, the public address is the address of the classic Bluetooth device, and the classic Bluetooth device is detected. If the connection fails, it is indicated that the current tested public address is not the classic bluetooth device address.
6. After the verification of one public address is finished, the host continues to process data packets returned by other micro bits. And the above process is repeated.
