Description

Data transmission method and electronic equipment

Technical Field

The application relates to the technical field of internet of things, in particular to a data transmission method and electronic equipment.

Background

There are a number of scenarios in real life that require the transfer of data from one device to another. For example, when a new device is replaced, it is necessary to transmit configuration information and the like in the old device to the new device. For another example, when a plurality of IoT devices of the same model are newly purchased, configuration information of the IoT devices that have been set in the IoT devices needs to be cloned to other IoT devices.

Currently, a third-party device (for example, a device installed with clone application software, or a gateway device, or a server) is generally required to be relied on to complete data transmission between two devices. Specifically, the device for sending data establishes a connection with the third-party device first, and sends the data to be sent to the third-party device. Then, the third-party device establishes a connection with the device receiving the data, and forwards the data to be sent to the device receiving the data. Therefore, a user needs to perform connection, data export, and data import on a plurality of devices, which is cumbersome to operate. In addition, when the data to be transmitted is sensitive data such as distribution network information, configuration information of equipment, user data and the like, the data to be transmitted is exported and cached, and leakage risks exist on third-party equipment.

Fig. 1 is a schematic diagram of an application scenario provided in an embodiment of the present application. As shown in fig. 1, a first electronic device 100 and a second electronic device 200 may communicate wirelessly.

For example, in the embodiment of the present application, the first electronic device 100 may be a mobile device, a home appliance, a sensor device, or the like. For example, the first electronic device 100 may be a mobile device such as a mobile phone, a tablet computer, a Personal Computer (PC), a Personal Digital Assistant (PDA), a netbook, a wearable device (e.g., a smart watch, a smart bracelet), an Augmented Reality (AR) device, a Virtual Reality (VR) device, an in-vehicle device, a smart screen, a smart speaker, and a smart camera. For another example, the first electronic device 100 may be an intelligent household appliance such as an intelligent refrigerator, an intelligent television, an intelligent lamp, an intelligent socket, an intelligent air purifier, a humidifier, an intelligent range hood, an intelligent door lock, an intelligent patch board, an intelligent induction cooker, an intelligent fan, an intelligent disinfection box, and an intelligent aromatherapy machine. For another example, the first electronic device 100 may be a sensor device such as a smoke sensor, a gas sensor, a human body sensor, a temperature sensor, a humidity sensor, a door/window sensor, a PM2.5 air sensor, a door/window switch sensor, an emergency button, or an alarm. The second electronic device 200 may also be any one of a mobile device, an electric home appliance, or a sensor device. The embodiment of the present application does not limit the specific forms of the first electronic device 100 and the second electronic device 200.

The structure of the first electronic device 100 is explained below. It should be noted that the second electronic device 200 may also refer to the structure of the first electronic device 100, but the second electronic device 200 may include more or less components than the first electronic device 100, or combine some components, or split some components, or arrange different components. The second electronic device 200 may be an electronic device of the same type as the first electronic device 100, or an electronic device of a different type, which is not limited in this embodiment of the application.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a first electronic device 100 according to an embodiment of the present disclosure. The first electronic device 100 may include one or more processors 110, one or more memories 120, and one or more communication interfaces 130, a wireless communication module 140, and one or more antennas, among others. The processor 110, the memory 120, the communication interface 130, and the wireless communication module 140 are connected by a bus.

The processor 110 may be a general-purpose Central Processing Unit (CPU), a microprocessor, an Application-Specific Integrated Circuit (ASIC), or an Integrated Circuit for controlling the execution of the program in the present embodiment. In one example, the processor 110 may include multiple CPUs, and the processor 110 may be one single-core (single-CPU) processor or a multi-core (multi-CPU) processor. A single-core processor or a processor in a multi-core processor may refer to one or more devices, circuits, or processing cores for processing data (e.g., computer program instructions).

Memory 120 may be used to store computer-executable program code, including instructions. The internal memory may include a program storage area and a data storage area. The storage program area may store an operating system, and programs or instructions and the like that are required to be used in the embodiments of the present application.

Communication interface 130 may be used to communicate with other devices or communication networks, such as ethernet, Wireless Local Area Networks (WLAN), etc. In some examples, the first electronic device 100 may not include the communication interface 130, which is not limited in this embodiment.

The wireless communication module 140 may provide a solution for wireless communication applied on the first electronic device 100, including WLAN (e.g., Wi-Fi) network), bluetooth, NFC, infrared technology, etc. The wireless communication module 140 may be one or more devices integrating at least one communication processing module. The wireless communication module 140 receives electromagnetic waves via an antenna, performs frequency modulation and filtering processing on electromagnetic wave signals, and transmits the processed signals to the processor 110. Wireless communication module 140 may also receive signals to be transmitted from processor 110, frequency modulate them, amplify them, and convert them into electromagnetic waves via an antenna for radiation.

In some embodiments, as shown in fig. 2, the first electronic device 100 includes at least two antennas, such as antenna 1 (the first antenna, also referred to as a strong antenna) and antenna 2 (the second antenna, also referred to as a weak antenna). The wireless communication module 140 may switch between antenna 1 and antenna 2. The transmission power applied to the antenna 1 or the antenna 2 is the same. Wherein, the transmitting distance of the antenna 1 is a first distance. The transmission distance of the antenna 2 is the second distance. The second distance is less than the first distance. For example, when the wireless communication module 140 switches to the antenna 1 to transmit a wireless signal, electronic devices located within a first distance (e.g., the first distance is 6m, 8m, 10m) of the first electronic device 100 may receive the wireless signal. When the wireless communication module 140 switches to the antenna 2 to transmit a wireless signal, an electronic device located within a second distance (e.g., the second distance is 30cm) of the first electronic device 100 may receive the wireless signal. The second distance is less than or equal to a preset safety distance. The preset safety distance is smaller than the first distance. The first distance, the second distance and the preset safety distance can be adjusted and set by a user according to needs. In one embodiment, the second distance may be a preset safety distance. In other words, when the first electronic device 100 needs to transmit an ultra-short range wireless signal, the wireless communication module 140 may be controlled to be connected to the antenna 2 to transmit the ultra-short range wireless signal. When the first electronic device 100 does not need to transmit an ultra-short range wireless signal, the wireless communication module 140 may be controlled to be connected to the antenna 1 to transmit a normal wireless signal.

In other embodiments, as shown in FIG. 3, the first electronic device 100 may include a variable resistance circuit module 150 and an antenna. The variable resistance circuit module 150 may change the magnitude of the resistance value under the control of the wireless communication module 140, thereby changing the transmission distance of the same antenna. That is, when the resistance value of the variable resistance circuit module 150 is adjusted to the resistance value 1, the transmission power of the antenna is the first transmission power (higher transmission power), and the transmission distance of the antenna is the first distance. At this time, electronic devices located within a first distance (e.g., the first distance is 6m, 8m, 10m) of the first electronic device 100 may receive the wireless signal. When the resistance value of the variable resistance circuit module 150 is adjusted to the resistance value 2, the transmission power of the antenna is the second transmission power (lower transmission power), and the transmission distance of the antenna is the second distance. The second transmit power is less than the first transmit power. The second distance is less than or equal to a preset safety distance. The preset safety distance is smaller than the first distance. The first distance, the second distance and the preset safety distance can be adjusted and set by a user according to needs. In one embodiment, the second distance may be a preset safety distance. In other words, when the first electronic device 100 needs to transmit the ultra-short distance wireless signal, the resistance value of the variable resistance circuit module 150 may be controlled to be adjusted to the resistance value 2 to transmit the ultra-short distance wireless signal. When the first electronic device 100 does not need to transmit the ultra-short distance wireless signal, the resistance value of the variable resistance circuit module 150 may be controlled to be adjusted to 1 so as to transmit the normal wireless signal. In other words, in the other embodiments, when the resistance value of the variable resistance circuit module 150 is adjusted to be 1, the first electronic device 100 is connected to the first antenna. When the resistance value of the variable resistance circuit module 150 is adjusted to the resistance value 2, the first electronic device 100 is connected to the second antenna; the first antenna and the second antenna are the same, but the transmission distance of the first antenna is greater than that of the second antenna; the transmitting distance of the second antenna is smaller than or equal to the preset safety distance, and the transmitting distance of the first antenna is larger than the preset safety distance. The transmission distance of the first antenna and the transmission distance of the second antenna are the first distance and the second distance respectively.

For example, the wireless communication mode adopted by the wireless communication module 140 may specifically adopt a mode such as BLE, Wi-Fi Aware, and the like. The wireless communication mode is based on the computer network MAC (Medium Access Control) layer, also called as interaction by data link layer protocol extension, and data interaction can be completely realized at the data link layer without involving upper network communication of the MAC layer. BLE is an ultra-low power consumption short-range wireless communication scheme for device B introduced by the bluetooth special interest group in 2016, and communication can be achieved through the MAC layer. Wi-Fi neighbor discovery Network (also called Wi-Fi neighbor discovery Network, NAN for short) is a novel Wi-Fi Mesh communication technology with low power consumption and Point-to-Point interconnection and intercommunication, and the technology can bypass Network infrastructure (such as Access Point (AP) or cellular Network), realize connection communication among one-to-one, one-to-many or many-to-many devices, and also realize communication through an MAC layer. It will be appreciated that the higher the number of layers of the computer network involved, the more difficult it is to ensure its security. The wireless-based MAC layer communication adopted in this embodiment enables data to interact based on a data link layer protocol extension, which can significantly improve the security of data transmission.

The technical solutions in the following embodiments can be implemented in the first electronic device 100 and the second electronic device 200 having the above-described structures. The first electronic device and the second electronic device each include a first antenna and a second antenna. The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

Fig. 4 is a schematic flowchart of a data transmission method according to an embodiment of the present application. As shown in fig. 4, the method includes:

s401, the first electronic device receives an input.

S401', the second electronic device receives an input.

Wherein the first electronic device receives an input instructing the first electronic device to transmit specific data. The input may be user input or may be an instruction sent by another device. The user input includes a user operating a specific key, inputting a voice command, a specific touch operation, a specific air-separating gesture, and the like.

The second electronic device receives an input instructing the second electronic device to receive specific data. The input may be user input or may be an instruction sent by another device. The user input includes a user operating a specific key, inputting a voice command, a specific touch operation, a specific air-separating gesture, and the like.

In some embodiments, the first electronic device stores configuration information including, but not limited to, network settings, sensor alarm threshold settings, alarm trigger actions, quiet time settings, timer settings, firmware upgrade settings, power usage threshold settings, and the like. Wherein the distribution network information for example comprises an identification of the Wi-Fi network (e.g. Service Set Identifier (SSID), password, etc.) information, it is noted that the configuration information differs depending on the device type, model, etc. of the first electronic device, the second electronic device is a device that is not Set, wherein the first electronic device receives an input, which may be an operation instructing the first electronic device to send configuration information to the second electronic device, for example a predefined operation 1 is performed on the first electronic device for the user, wherein the predefined operation 1 is for example a pressing of a specific key (physical key or virtual key) on the first electronic device. The predefined operation 2 is for example a power-on or an instruction to set the operation of the second electronic device.

As an example, the first electronic device and the second electronic device are of the same device type, with the same or close model. Then, the configuration information of the first electronic device may be sent to the second electronic device, and the second electronic device may directly perform setting according to the received configuration information. As another example, the first electronic device and the second electronic device are of different device types. Part of configuration information in the first electronic device can be sent to the second electronic device, and the second electronic device can directly perform device operation according to the received part of configuration information. For example, when the first electronic device and the second electronic device need to access the same network, the second electronic device may also directly use the configuration information of the network setting of the first electronic device.

In other embodiments, the first electronic device is an old device used by the user and the second electronic device is a new device to be replaced by the user. Wherein the first electronic device receives an input, such as an operation instructing the first electronic device to send configuration information and/or user data to the second electronic device. That is, the specific data is configuration information and/or user data of the first electronic device. The user data includes, but is not limited to, information of an installed application program of the first electronic device, basic settings of the installed application program, a photo, a video, a sound recording, a file stored on the first electronic device, an operation log of the first electronic device, and the like. The second electronic device receives an input such as an operation to turn on the wireless function for the user or an operation to instruct to receive specific data.

It should be noted that, in the embodiment of the present application, the execution sequence of S401 and S401' is not limited.

S402, the first electronic device sends a first message in a first period through a first antenna.

Wherein the first message is for requesting transmission of specific data to the second electronic device in order to negotiate a session key with the second electronic device.

In some embodiments, the first electronic device may broadcast the request wirelessly, such as via Wi-Fi or Bluetooth. The first electronic device sends the service identifier for transmitting specific data by using Wi-Fi Aware technology as an example.

First, the NAN mechanism is briefly explained. The NAN mechanism is a standard established by the Wi-Fi alliance. The standard is that all devices participating in the NAN mechanism (i.e. NAN devices, e.g. first electronic device, second electronic device) synchronize without a central node. The maintenance work and the service discovery work of the NAN mechanism are carried out in a Discovery Window (DW) agreed by the NAN mechanism. Wherein the service discovery may be implemented by transmitting a Service Discovery Frame (SDF) message. The server discovery frame message includes a query message or a broadcast message. The NAN device may establish a corresponding connection based on information obtained in the service discovery message, and then may be intelligently managed based on the NAN. Among them, the SDF message is a kind of action frame specifically defined for service discovery. Depending on the function, the SDF message frame can be roughly divided into three types, namely, an SDF publish (publish) message, an SDF subscribe (subscribe) message, and an SDF reply (follow-up) message. The SDF publish message is used for publishing services which can be provided by the NAN device, or replying the NAN describe message sent by other NAN devices. NAN subscribe message for finding the service to use. SDF follow-up message for replying to received SDF publish message or for negotiating more information. Typically, an indication is included in the SDF message to indicate to which SDF message the message belongs.

As an example, the first electronic device may carry information such as a service identifier for transmitting specific data, an identifier of the first electronic device, and the like in the SDF publish message. As another example, the first electronic device may carry information such as a service identifier for transmitting specific data, an identifier of the first electronic device, and the like through the BLE beacon.

In still other embodiments, the first electronic device can obtain the identifier of the second electronic device or the address of the second electronic device, and may also send the first message in a peer-to-peer manner.

In still other embodiments, the first electronic device may send the first message at the first cycle within a preset time period, or may send the first message a preset number of times within the preset time period. The embodiment of the present application does not limit this.

And S403, the second electronic device receives the first message and switches to a second antenna of the second electronic device.

S404, the second electronic device generates a first random number and generates a second message according to the first random number.

Illustratively, upon receiving a request for transmission of specific data sent by the first electronic device, the second electronic device generates first random data for negotiating a session key with the second electronic device.

The execution order of S403 and S404 is not limited in the embodiments of the present application.

And S405, the second electronic device sends a second message in a second period through a second antenna.

For example, when the second electronic device has the structure shown in fig. 2, the second electronic device may control the wireless communication module 140 to connect to the second antenna. For example, when the second electronic device has the structure shown in fig. 3, the second electronic device controls the resistance value of the variable resistance circuit module 150 to be the second resistance value (larger resistance value) so that the antenna transmission power of the second electronic device is the second transmission power.

As one example, the second electronic device may carry a first random number in an SDF Follow-up message. As another example, the second electronic device may carry the first random number through BLE beacon.

It has been explained above that due to the second message transmitted by the second electronic device via the second antenna, only electronic devices within a very short distance range (e.g. 30cm) from the second electronic device can receive it. Thus, the electronic device receiving the second message may be guaranteed to be a trusted device of the second electronic device.

In some embodiments, before the second electronic device sends the second message, the second electronic device may prompt the user to bring the first electronic device close to the second electronic device by means of a voice prompt or a lamp flashing. Of course, the second electronic device may prompt the user at other occasions, for example, after receiving the first message sent by the first electronic device. The user may also be prompted by the first electronic device to approach the second electronic device. The embodiment of the application does not limit the prompting mode, the prompting time and the like.

And S406, within the transmission distance of the second antenna of the second electronic device, the first electronic device receives the second message to acquire the first random number.

S407, the first electronic device is switched to the second antenna of the first electronic device.

S408, the first electronic device generates a second random number and generates a third message according to the second random number.

And S409, the first electronic equipment sends a third message through the second antenna.

In S407-S409, in addition, a process of the first electronic device sending the third message is the same as or similar to a process of the second electronic device sending the second message, and is not described herein again. Other contents may refer to the relevant description in S405.

As one example, the first electronic device may carry the second random number in an SDF Follow-up message. As another example, the first electronic device may carry the second random number in BLE beacon.

And S410, the first electronic equipment generates a session key according to the first random number and the second random number.

For example, the first electronic device may calculate the session key using a predefined algorithm or a Key Derivation Function (KDF) in cryptography. The predefined algorithm includes, but is not limited to, data splicing, data encoding format conversion, data position conversion, HASH (HASH) operation (e.g., MD5/SHA-1, etc.), and the like. KDF algorithms include, for example, PBKDF2, bcrypt, scrypt, HKDF (HMAC-based KDF), and the like. The embodiment of the present application does not limit the specific method for generating the session key according to the first random number and the second random number.

S411, the first electronic device switches to a first antenna of the first electronic device.

Specifically, for example, when the first electronic device has the structure shown in fig. 2, the first electronic device may control the wireless communication module 140 to connect to the first antenna. For example, when the first electronic device has the structure shown in fig. 3, the first electronic device controls the resistance value of the variable resistance circuit module 150 to be the first resistance value (smaller resistance value) so that the antenna transmission power of the first electronic device is the first transmission power.

In other embodiments, the first electronic device may switch to the first antenna at other times as well. For example, after performing S409, that is, after sending the third message, the first electronic device switches back to the first antenna. For another example, before performing S413, that is, sending the fourth message to the second electronic device through the first antenna to the first electronic device, the first electronic device switches back to the first antenna. The embodiment of the present application does not limit this.

S412, the first electronic device encrypts the specific data of the first electronic device by using the session key to obtain encrypted data, and generates a fourth message according to the encrypted data.

The first electronic equipment adopts a certain encryption algorithm to encrypt the specific data by using the session key and generates the signature or integrity check information of the specific data so as to ensure the security of transmitting the specific data and avoid the leakage of the specific data.

In the process of the first electronic device performing S410-S412, the second electronic device performs S410 '-S412'. The method comprises the following specific steps:

s410', within the transmission distance of the second antenna of the first electronic device, the second electronic device receives the third message and obtains the second random number.

S411', the second electronic device switches to the first antenna of the second electronic device.

Specifically, for example, when the second electronic device has the structure shown in fig. 2, the second electronic device may control the wireless communication module 140 to connect to the first antenna. Further illustratively, when the second electronic device has the structure shown in fig. 3, the second electronic device controls the resistance value of the variable resistance circuit module 150 to be the first resistance value (smaller resistance value), so that the antenna transmission power of the second electronic device is the first transmission power.

In some other embodiments, the second electronic device may switch to the first antenna at other times, for example, after S405 is executed, that is, after the second message is sent, the second electronic device switches back to the first antenna. For another example, before performing S416, that is, the second electronic device sends a message that the specific data transmission is successful to the first electronic device through the first antenna, the second electronic device switches back to the first antenna. The embodiment of the present application does not limit this.

S412', the second electronic device generates a session key according to the first random number and the second random number.

It should be noted that, here, the algorithm used by the second electronic device to generate the session key is the same as the algorithm used by the first electronic device to generate the session key, so that the session keys generated by the two electronic devices are the same. Further, the generated session key may be used to decrypt data transmitted by the peer electronic device.

S413, the first electronic device sends the fourth message through the first antenna.

Illustratively, the first electronic device may broadcast the encrypted specific data by way of a wireless connection (e.g., Wi-Fi or bluetooth). For example, the second electronic device may carry encrypted specific data in an SDF Follow-up message or in a BLE beacon. Alternatively, the first electronic device establishes a point-to-point wireless connection (e.g., Wi-Fi or bluetooth) with the second electronic device, and transmits the encrypted specific data to the second electronic device through the wireless connection.

And S414, the second electronic device receives the fourth message and acquires the encrypted data.

S415, the second electronic device decrypts the encrypted data using the session key to obtain the specific data of the first electronic device.

The second electronic device decrypts the encrypted specific data using the session key, and verifies the signature or integrity check information of the specific data.

And S416, the second electronic device sends a message that the specific data transmission is successful through the first antenna.

S417, the first electronic device receives the specific data transmission success message, displays the specific data transmission success message and/or plays the voice of the specific data transmission success.

S417', the second electronic device displays a message that the transmission of the specific data is successful and/or plays a voice that the transmission of the specific data is successful.

In this embodiment, the execution order of S417 and S417' is not limited. In addition, in the embodiment of the present application, either one of the steps S417 and S417' may be executed, both the steps may be executed, or neither of the steps may be executed.

Therefore, in the data transmission method provided in the embodiment of the present application, the first electronic device and the second electronic device negotiate a session key by switching to the second antenna to transmit the ultra-short distance wireless signal, thereby completing authentication of both parties. The first electronic device and the second electronic device can receive the ultra-short distance wireless signal sent by the opposite-end electronic device only when the first electronic device and the second electronic device are located within the transmitting distance of the second antenna (the transmitting distance of the second antenna is smaller than or equal to the preset safety distance). Therefore, the session key is negotiated by sending the ultra-short distance wireless signal, so that the communication safety can be improved, the key negotiation process can be simplified, and the specific data can be transmitted quickly. Moreover, it can be noted that the user does not need to manually input information such as the verification code in the key agreement process, and the complexity of the user operation is also reduced.

For example, the integrity check algorithm may hash the encrypted data by using a hash algorithm and a key to obtain a hash value of the data (i.e., a first integrity check value), and then send the hash value and the encrypted data to the second electronic device, so that after the second electronic device receives the hash value and the encrypted data, another hash value (i.e., a second integrity check value) is calculated for the encrypted data by using the same integrity check algorithm. When the second integrity check value is equal to the first integrity check value, the encrypted data is complete and is not tampered. Then, the specific data that has not been tampered with is acquired from the entire encrypted data. Of course, other integrity check algorithms may also be used, which is not limited in this application.

In the process of the first electronic device performing S510-S512, the second electronic device performs S510 '-S512'. The method comprises the following specific steps:

The following describes a few exemplary application scenarios of the technical solutions provided in the embodiments of the present application.

Scenario one, a user newly purchases a large number of devices of the same or similar device type. The setting information of these devices is the same or similar. Thus, the user can first set one of the electronic devices through, for example, a mobile phone. The set electronic device is the first electronic device. Then, the configuration information of the set electronic device is directly cloned to other electronic devices (i.e. second electronic devices) to complete the setting of the other electronic devices.

For example, a plurality of intelligent lighting devices (intelligent desk lamps, ceiling lamps, intelligent lamp strips, fragrance lamps, etc.) are newly purchased. The user can establish wireless connection with the lighting device A through the mobile phone, and through intelligent life or other applications, the lighting device is subjected to distribution network and brightness, color temperature and other lighting parameters, whether to delay closing, delay closing time, whether to automatically update firmware, set power consumption threshold and the like. That is, the lighting apparatus a stores the configuration information. The user may then clone the configuration information for lighting fixture a onto other lighting fixtures (e.g., lighting fixture B, lighting fixture C, etc.).

In one embodiment, the configuration data of lighting device a is transmitted to lighting device B when lighting device a and lighting device B are within 30cm of each other after receiving one input, respectively. Therefore, after the user only needs to trigger one input to the lighting device A and the lighting device B, the lighting device A and the lighting device B are close to each other to a preset safety distance, and the lighting device A and the lighting device B can transmit specific data. The operation of the user is very simple and convenient, and the method is particularly suitable for the old, children and other people with weak understanding ability and operation ability, and is convenient to master.

In one embodiment, the specific data may be preset by a control device or a binding device of the electronic device. For example, a host's cell phone may preset specific data of IoT lights as configuration data.

It should be noted that, in the embodiment of the present application, a secret key is transmitted at a secure distance in ultra-short distance wireless communication, when the first antenna operates, data encrypted by the secret key is transmitted, and decryption is implemented at another electronic device, so that security of transmission between the lighting device a and the lighting device B is physically ensured, and attacks from intermediate devices and risks of data leakage are eliminated.

Cloning the configuration information of the lighting device a to other devices such as the lighting device C can then be done in the same way. Alternatively, the configuration information of the lighting apparatus B is cloned to other apparatuses such as the lighting apparatus C by the same method.

As can be seen from the above, when the same configuration information needs to be set for a plurality of electronic devices, one of the electronic devices may be set first. And then, directly cloning the configuration information in the set electronic equipment to other electronic equipment. The method simplifies the process of respectively setting the plurality of electronic devices by the user, and improves the efficiency of setting the plurality of electronic devices.

For another example, in smart home life, a large number of sensors are generally required. Such as smoke sensors, gas sensors, water immersion detectors, abnormal sound sensors, etc. The sensors, although of different types, are substantially identical or similar in configuration information. The configuration information includes, for example, network information of the access network, alarm trigger actions, quiet time, timer settings, firmware upgrade settings, etc. Therefore, the method of the embodiment of the application can be adopted, one sensor is set first, and then the set sensor is used for cloning the configuration information to other sensors, so that repeated setting of similar sensors is avoided, user operation is simplified, and setting efficiency is improved.

In addition, the method provided by the embodiment of the application rarely relates to user interface operation, so that the method provided by the embodiment of the application is more friendly and convenient to implement for a large amount of devices without display screens in smart homes.

And in the second scenario, the user uses the new electronic equipment to replace the old electronic equipment. The new electronic device is typically the same type of device as the old electronic device and is of a similar model. Then the configuration information and/or user data on the old electronic device can be cloned directly onto the new electronic device. Therefore, configuration information and/or user data on the old electronic equipment are prevented from being exported to the intermediate equipment and then exported to the new electronic equipment by the intermediate equipment, the data security is improved, and the user operation is simplified.

And in a third scenario, an IoT device which cannot be connected to the internet or fails in the distribution network in the family has an operation fault. Generally, when an IoT device fails, the operation log is sent to a mobile phone or a computer through a network. Or, the IoT device prints the operation log to a mobile phone or a computer through a communication interface such as a serial port, so that the user can perform fault analysis and problem location. In the scheme, the operation log of the IoT device can be sent to other electronic devices in an ultra-short distance manner, and the operation log of the electronic device can be checked through the other electronic devices, so that the electronic device can be conveniently subjected to fault analysis, and the electronic device can be maintained. Therefore, the maintenance problem of the IoT equipment which cannot be connected to the internet or fails to be connected to the network or does not have an external communication interface is solved.

For example, as shown in (1) in fig. 8, the user may open an APP "smart life" in the mobile phone and enter the home device list interface 801. Therefore, the mobile phone is bound with three devices, namely an air conditioner, an intelligent desk lamp and an intelligent sound box. Wherein, the intelligent desk lamp is in an unconnected state. Further, in response to the user operating the control 802, the mobile phone sends a message to the smart desk lamp to please collect the running log of the smart desk lamp, that is, S702 is executed, and the following steps are executed. In the process of collecting the smart desk lamp by the mobile phone, the mobile phone also displays a prompt interface 803 as shown in (2) in fig. 8. And prompt information 804 in the prompt interface 803 is used for prompting the user that the running log of the intelligent desk lamp is collected. After the mobile phone successfully receives the operation log of the intelligent desk lamp, the mobile phone may display a prompt interface 805, where the prompt information 806 is used to prompt the user that the operation log of the intelligent desk lamp has been successfully collected. Optionally, the reminder 806 also includes a view control 807. In response to the user operating the control 807, the mobile phone displays an operation log of the intelligent desk lamp, so that the user can conveniently perform fault analysis on the operation condition of the intelligent desk lamp. It should be noted that, in other embodiments, the mobile phone and the smart desk lamp may not be bound in advance, and the mobile phone may also request to collect the operation log of the smart desk lamp, which is not limited in this application.
