Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In some embodiments of the application, OTA upgrading is combined with a Mesh network, and an OTA data packet can be transmitted to an object to be upgraded by means of communication connection between a node device with direct OTA upgrading capability in the Mesh network and the object to be upgraded, so that the object to be upgraded realizes indirect OTA upgrading.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1a is a schematic structural diagram of a Mesh network according to an exemplary embodiment of the present application. As shown in fig. 1a, the Mesh network includes: a plurality of node devices 101 and a server device 102. The plural in the present embodiment means two or more. In addition, the number of the server devices 102 is not limited in this embodiment, and one or more server devices 102 may be provided.
In this embodiment, the implementation form of the node device 101 is not limited, and the node device 101 may be any terminal device with certain computing capability and communication capability, for example, a smart phone, a smart speaker, a tablet computer, a notebook computer, a desktop computer, a smart camera, a smart television, a wearable device, a wireless access device (AP), a router, a gateway device, or the like. Regardless of the implementation of node device 101, node device 101 will generally include at least one processing unit, at least one memory, and a communication module. The number of processing units and memories depends on the configuration and type of node device 101. The Memory may include volatile, such as RAM, non-volatile, such as Read-Only Memory (ROM), flash Memory, etc., or both. The memory typically stores an Operating System (OS), one or more application programs, and may also store program data and the like. In addition to the processing unit, the memory and the communication module, the node device 101 also includes some basic configurations, such as other types of network card chips, IO buses, audio-video components, and so on. Optionally, the node device 101 may also include some peripheral devices, such as a keyboard, mouse, stylus, printer, display, electronic screen, etc. These peripheral devices are well known in the art and will not be described in detail herein.
Similarly, in this embodiment, the implementation form of the server device 102 is not limited, and the server device 102 may be any server device that has certain computing and communication capabilities and can respond to the request of the node device 101 and provide corresponding services or data support for the node device 101, for example, may be a conventional server, a cloud host, a virtual center, a server array, or the like. The server device mainly includes a processor, a hard disk, a memory, a system bus, and the like, and is similar to a general computer architecture.
In this embodiment, a plurality of node apparatuses 101 are peer-to-peer and are connected to each other, and each node apparatus 101 may perform direct communication with other node apparatuses 101, and may send a message to other node apparatuses 101 or receive a message sent by other node apparatuses 101. At least one node device in the node devices 101 is in direct communication connection with the server device 102, so as to establish a communication link between the server device 102 and each node device 101; accordingly, the server device 102 is directly connected to at least one node device 101 in communication, and the communication connection may be a wired connection or a wireless connection.
Optionally, the server device 102 is deployed in the cloud, and the node device 101 may access the internet (e.g., a wide area network or a metropolitan area network) through a mobile network such as WiFi, ethernet, optical fiber, 2/3/4G/5G, and establish a communication connection with the server device 102 through the internet. Of course, in addition to being deployed in the cloud, the server device 102 may also be deployed together with the node device 101. In the present embodiment, the deployment location of the server device 102 is not limited.
In this embodiment, at least some of the node devices 101 are provided with direct OTA upgrade capability. For any node device 101, having the direct OTA upgrade capability means that the node device 101 supports the OTA technology, can directly receive OTA data packets sent by other devices through an over-the-air radio frequency signal, and upgrade local related resources according to the received OTA data packets; the "other device" may be any device capable of providing OTA packets to the node device 101 by using over-the-air radio frequency signals, for example, the node device 102 may be another node device different from the node device, or another device outside the Mesh network.
In this embodiment, the Mesh network provided by this embodiment is combined with OTA upgrade, and with the help of the communication connection between the node device having the direct OTA upgrade capability in the Mesh network and the object to be upgraded, the OTA data packet can be transmitted to the object to be upgraded, so that the object to be upgraded realizes indirect OTA upgrade.
The indirect OTA upgrade and the direct OTA upgrade are two relative concepts. The direct OTA upgrading refers to a mode that an object needing upgrading directly receives an OTA data packet sent by other equipment through an air radio frequency signal and upgrades local related resources according to the received OTA data packet. The indirect OTA upgrading is a mode that an object needing upgrading receives an OTA data packet sent by other equipment through an air radio frequency signal by means of another object, and local related resources are upgraded according to the OTA data packet received by the other object. The "object requiring upgrading" is a generic term, and refers to any object requiring upgrading, for example, the object to be upgraded in this embodiment, but is not limited thereto.
In this embodiment, the membership between the object to be upgraded and the Mesh network is not limited, and only the object to be upgraded is in communication connection with the node device in the Mesh network having the direct OTA upgrade capability. In an alternative embodiment, the object to be upgraded is a device, component, board or chip in the Mesh network, and these devices, components, boards or chips are separate from the node device with direct OTA upgrade capability. Fig. 1b is a schematic diagram of a network state of the Mesh network for performing indirect OTA upgrade on devices, components, boards or chips in the Mesh network based on the Mesh network of the present embodiment. In another alternative embodiment, the object to be upgraded is a device, component, board or chip, etc. outside the Mesh network. Fig. 1c is a schematic diagram of a network state in which the Mesh network performs indirect OTA upgrade on devices, components, boards, or chips that are required outside the Mesh network based on the embodiment.
In some application scenarios, due to the requirement of service interconnection, the Mesh network of this embodiment may need to maintain communication connection with devices, components, boards or chips in other networks or systems for a long time. In these scenarios, these devices, components, boards or chips may be used as objects to be upgraded outside the Mesh network of this embodiment, and these devices, components, boards or chips are indirectly upgraded OTA by virtue of the communication connection between these devices, components, boards or chips and the node device with direct OTA upgrade capability in the Mesh network of this embodiment at any time. Especially, in the case that the devices, components, boards or chips in other networks or systems do not have the direct OTA upgrade capability or the direct OTA upgrade capability is disabled, the devices, components, boards or chips can be indirectly OTA upgraded at any time by means of the communication connection between the devices, components, boards or chips and the node device having the direct OTA upgrade capability in the Mesh network of the embodiment.
In other application scenarios, there may be some devices, components, boards or chips used independently outside the Mesh network of this embodiment. Taking the home bluetooth Mesh network as an example, there may be some personal computers, routers, bracelets or mobile phones, etc. without adding the bluetooth Mesh network. In normal times, these devices, components, boards or chips can be used independently of the Mesh network of the present embodiment. Under the condition that the devices, components, boards or chips independent of the Mesh network of the embodiment need to be upgraded, especially under the condition that the devices, components, boards or chips do not have the direct OTA upgrading capability or the direct OTA upgrading capability is disabled, the devices, components, boards or chips can be used as objects to be upgraded outside the Mesh network of the embodiment, and the objects to be upgraded are in communication connection with a certain node device with the direct OTA upgrading capability in the Mesh network, so that the devices, components, boards or chips are indirectly upgraded in an OTA manner by means of the communication connection between the devices, components, boards or chips and the node device with the direct OTA upgrading capability in the Mesh network of the embodiment. Further, after the devices, components, boards or chips are waited for the upgrade of the upgrade object to be completed, the communication connection between the object to be upgraded and a certain node device with the direct OTA upgrade capability in the Mesh network can be disconnected, so that the devices, components, chips or boards enter an independent use state.
In addition, in this embodiment, the OTA capability of the object to be upgraded is not limited. Optionally, the object to be upgraded may not have a direct OTA upgrade capability, and on the basis of the communication connection between the object to be upgraded and the node device in the Mesh network having the direct OTA upgrade capability, the node device in the Mesh network having the direct OTA upgrade capability may transmit an OTA data packet required by the object to be upgraded to the object to be upgraded, so that the object to be upgraded performs indirect OTA upgrade according to the OTA data packet. Of course, for the object to be upgraded having the direct OTA upgrade capability, the node device having the direct OTA upgrade capability and being in communication connection with the node device in the Mesh network may also be used to transmit the OTA data packet required by the object to be upgraded to the object to be upgraded, so that the object to be upgraded performs indirect OTA upgrade according to the OTA data packet. Further optionally, for an object to be upgraded with a direct OTA upgrade capability, before performing indirect OTA upgrade on the object by using the method provided by the embodiment of the present application, the object may be further controlled to disable the direct OTA upgrade capability.
It should be noted that, regardless of whether the object to be upgraded has the direct OTA upgrade capability, the object to be upgraded and the node device in the Mesh network having the direct OTA upgrade capability may be communicatively connected in a wired manner. For example, the object to be upgraded may be via a serial interface, a USB interface, a PCIE interface, or I2The C interface is in wired connection with node equipment with direct OTA upgrading capability in the Mesh network. In this embodiment, the implementation form of the serial interface is not limited. For example, from the viewpoint of data transmission, the Serial Interface of the present embodiment may include a Universal Asynchronous Receiver/Transmitter (UART) Interface, or may be a Synchronous Serial Interface (SSI). In addition, the serial interface of the present embodiment may include various interfaces such as RS-232-C, RS-422 and RS485 in terms of electrical standards and protocols. For node equipment with direct OTA upgrading capability in a Mesh network, after receiving an OTA data packet required by an object to be upgraded through an over-the-air radio frequency signal, transmitting the OTA data packet to the object to be upgraded through wired connection between the node equipment and the object to be upgraded; after receiving the OTA data packet, the object to be upgraded performs OTA upgrade on the local related data, and the OTA upgrade process is called indirect OTA upgrade.
Of course, the object to be upgraded and the node device in the Mesh network having the direct OTA upgrade capability may be in communication connection in a wireless manner, in addition to the wired manner. Optionally, in a case that the object to be upgraded and the node device in the Mesh network having the direct OTA upgrade capability are in communication connection in a wireless manner, a user-defined download protocol (download) may be used for data transmission between the object to be upgraded and the node device connected thereto.
The process of performing indirect OTA upgrading on the object to be upgraded by means of the node equipment with the direct OTA upgrading capability in the Mesh network is the same or similar regardless of whether the object to be upgraded has the direct OTA upgrading capability, whether the object to be upgraded is attached to the Mesh network, and the communication connection between the object to be upgraded and the node equipment with the direct OTA upgrading capability in the Mesh network. The following embodiment will describe a process of performing indirect OTA upgrade on an object to be upgraded by using a node device having a direct OTA upgrade capability in a Mesh network.
In the OTA upgrade method of some embodiments of the present application, a first node device and a second node device are involved. The second node equipment is connected with an object to be upgraded in a communication mode in the Mesh network and has direct OTA upgrading capability; the first node device is another node device different from the second node device in the Mesh network, is equivalent to a control end of an OTA upgrading process, and mainly provides an OTA data packet for the object to be upgraded through the second node device so as to indirectly upgrade the object to be upgraded by the OTA. As shown in fig. 2a, described from the perspective of a first node device, an OTA upgrade method comprises the steps of:
and 21a, obtaining an upgrading instruction, wherein the upgrading instruction comprises an identifier of an object to be upgraded and an identifier of a second node device which is in communication connection with the object to be upgraded in the Mesh network and has a direct OTA upgrading capability.
22a, according to the identification of the object to be upgraded and the identification of the second node device, transmitting an OTA data packet to the object to be upgraded through the second node device so as to allow the object to be upgraded to carry out indirect OTA upgrade.
The identifier of the object to be upgraded may be any information capable of uniquely identifying the object to be upgraded, and may be, for example, a name, a serial number, an IP address, an MAC address, or the like of the object to be upgraded. Accordingly, the identifier of the second node device may be any information capable of uniquely identifying the second node device, and may be, for example, a name, a serial number, an IP address, a MAC address, or the like of the second node device.
In this embodiment, the first node device obtains an upgrade instruction, and analyzes an identifier of an object to be upgraded and an identifier of the second node device from the upgrade instruction; and then, according to the identification of the object to be upgraded and the identification of the second node equipment, transmitting an OTA data packet to the object to be upgraded through the second node equipment so as to carry out indirect OTA upgrade on the object to be upgraded.
The transmission of the OTA data packet to the object to be upgraded by the second node device mainly refers to a process that the first node device transmits the OTA data packet to the second node device through an over-the-air radio frequency signal, and the second node device transmits the received OTA data packet to the object to be upgraded through a communication connection between the second node device and the object to be upgraded.
For the object to be upgraded, the OTA data packet transmitted by the second node device can be received, and the local related resources are upgraded according to the OTA data packet. The OTA data packet is a data packet required by the object to be upgraded for indirect OTA upgrade. The content of the OTA data packet is not limited in this embodiment, and may be determined according to the specific upgraded resource type in the object to be upgraded. For example, if the firmware in the object to be upgraded is upgraded, the OTA data packet may be a firmware upgrade packet; if the application program installed in the object to be upgraded is upgraded, the OTA data package can be a new edition installation package of the application software.
According to different application scenarios, the manner in which the first node device obtains the upgrade instruction may also be different. This is exemplified below in connection with the embodiments shown in fig. 2b and 2 c.
In an alternative embodiment, depicted in fig. 2b, from the perspective of the first node device, another OTA upgrade method comprises:
21b, the first node device receives an upgrading instruction issued by the server device, wherein the upgrading instruction comprises an identifier of an object to be upgraded and an identifier of a second node device which is in communication connection with the object to be upgraded in the Mesh network and has direct OTA capability.
22b, the first node equipment transmits the OTA data packet to the object to be upgraded through the second node equipment according to the identification of the object to be upgraded and the identification of the second node equipment, so that the object to be upgraded is subjected to indirect OTA upgrade.
In this embodiment, a user or a network administrator may deploy an upgrade task on a server device in the Mesh network, where the upgrade task carries an identifier of an object to be upgraded and an identifier of a node device in the Mesh network, which is in communication connection with the object to be upgraded and has direct OTA capability. The node device here is the second node device. The user may be a user of the object to be upgraded, or may be a provider of the object to be upgraded. Further optionally, the upgrade task further includes an OTA data packet required by the object to be upgraded, or a storage address or an access path of the OTA data packet.
The server-side equipment responds to the upgrading task deployment operation, can acquire the upgrading task deployed by the user or the network administrator, and sends an upgrading instruction to the first node equipment according to the upgrading task deployed by the user or the network administrator. The upgrade instruction includes an identifier of the object to be upgraded and an identifier of the second node device. Further optionally, the upgrade instruction may further include an OTA data packet required by the object to be upgraded, or a storage address or an access path of the OTA data packet.
Optionally, before the server device issues the upgrade instruction to the first node device, the first node device may be selected from the Mesh network according to a certain policy. For example, the server device may select, as the first node device, a node device having a signal strength greater than a set signal strength threshold or a signal strength maximum from the signal strengths of the node devices in the Mesh network. For another example, the server device may select a node device with the lightest load as the first node device according to the load condition of each node device in the Mesh network. For another example, the server device may select, as the first node device, a node device with the largest or smallest IP address from the IP addresses of the node devices in the Mesh network. For another example, the server device may select a node device in the gateway role as the first node device according to the roles of the node devices in the Mesh network.
For the first node equipment, the upgrading instruction issued by the server side equipment is received, the identification of the object to be upgraded and the identification of the second node equipment are analyzed from the upgrading instruction, and further an OTA data packet can be transmitted to the object to be upgraded through the second node equipment according to the identification of the object to be upgraded and the identification of the second node equipment, so that the object to be upgraded can be subjected to indirect OTA upgrading.
Before transmitting the OTA data packet to the object to be upgraded through the second node device, the first node device may obtain the OTA data packet required for upgrading the object to be upgraded by using, but not limited to, the following several embodiments:
in an alternative embodiment a1, the upgrade instruction carries the OTA packet required by the object to be upgraded, or the storage address or access path of the OTA packet. Based on the method, the first node equipment can analyze the OTA data packet required by the object to be upgraded from the upgrading instruction; or analyzing the storage address or the access path of the OTA data packet required by the object to be upgraded from the upgrading instruction, and acquiring the OTA data packet required by the object to be upgraded according to the analyzed storage address or the access path.
In another alternative embodiment a2, the user or the network administrator may directly store the OTA data packet required for the object to be upgraded in advance in the first node device, or may provide the storage address or access path of the OTA data packet to the first node device in advance. Based on the above, the first node device may directly obtain the OTA data packet required by the object to be upgraded from the local according to the identifier of the object to be upgraded; or, locally acquiring a storage address or an access path of an OTA data packet required by the object to be upgraded, and acquiring the OTA data packet required by the object to be upgraded according to the analyzed storage address or access path.
In yet another alternative embodiment a3, the first node device may locally store some OTA packets required for object upgrade, which may include objects that have been upgraded before, or may include objects that have been upgraded but have not yet been upgraded with OTA upgrade requirements. The OTA data packet locally stored by the first node device may or may not include the OTA data packet required by the object to be upgraded. Based on the above, the first node device may query whether to locally store the OTA data packet required by the object to be upgraded according to the identifier of the object to be upgraded; if the OTA data packet required by the object to be upgraded is inquired locally, acquiring the OTA data packet required by the locally stored object to be upgraded; and if the OTA data packet required by the object to be upgraded is not inquired locally, acquiring the OTA data packet required by the object to be upgraded from the server-side equipment of the Mesh network or a third-party server. The third party server corresponds to the object to be upgraded and can be responsible for providing the OTA data packet required by the object to be upgraded.
In some application scenarios, the third-party server uploads the OTA data packet required by the object to be upgraded to the server device of the Mesh network in advance, and the OTA data packet required by the object to be upgraded can be acquired from the server device of the Mesh network by the first node device under the condition that the OTA data packet required by the object to be upgraded is not queried locally. For example, the first node device may send a data request to a server device of the Mesh network, where the data request includes an identifier of an object to be upgraded, so as to request the server device of the Mesh network to acquire an OTA data packet required by the object to be upgraded; after receiving the data request, the server device of the Mesh network may obtain an OTA data packet required by the object to be upgraded, and return the OTA data packet to the first node device.
In other application scenarios, the third-party server may directly provide the OTA data packet required by the object to be upgraded, and the first node device may obtain the OTA data packet required by the object to be upgraded from the third-party server when the OTA data packet required by the object to be upgraded is not queried locally. For example, the first node device may send a data request to the third-party server, where the data request includes an identifier of the object to be upgraded, so as to request the third-party server to acquire an OTA data packet required by the object to be upgraded; after receiving the data request, the third-party server may obtain an OTA data packet required by the object to be upgraded, and return the OTA data packet to the first node device.
Further, for the condition that the first node device does not inquire the OTA data packet required by the object to be upgraded locally, after the first node device acquires the OTA data packet required by the object to be upgraded from the server device of the Mesh network or the third-party server, the first node device can also store the OTA data packet acquired from the server device of the Mesh network or the third-party server locally, so that the OTA data can be directly acquired locally during next upgrade, network resources are saved, and upgrade efficiency is improved.
In addition to storing the OTA data packet locally in the manner described above, the first node device may also locally cache the OTA data packet in the following manner. Mode 1: the first node equipment can identify an object needing OTA upgrading from the connected objects as a candidate object according to a certain strategy; the number of candidates may be one or more; and pulling (pull) OTA data packets required by candidate object upgrading from a server device or a third-party server of the Mesh network, and storing the OTA data packets required by the candidate object upgrading locally. Mode 2: a server device or a third-party server of the Mesh network can identify an object needing OTA upgrading from objects connected with the first node device as a candidate object according to a certain strategy, and actively push (push) an OTA data packet required by the candidate object upgrading to the first node device; for the first node device, an OTA data packet required for candidate object upgrade pushed by a server device of the Mesh network or a third-party server may be received, and the OTA data packet required for candidate object upgrade may be stored locally.
It should be noted that the object connected to the first node device is dynamically changed, and the candidate object is also dynamically changed, so that after receiving the upgrade instruction, the first node device needs to determine whether to locally store the OTA data packet required by the object to be upgraded according to the identifier of the object to be upgraded.
In a further alternative embodiment a4, the OTA data packets required for the object to be upgraded are stored on the server device of the Mesh network or on a third party server. After receiving the upgrade instruction, the first node device needs to acquire the OTA data packet required by the object to be upgraded from the server device of the Mesh network or a third-party server before transmitting the OTA data packet required by the first node device to the object to be upgraded through the second node device.
For example, after receiving the upgrade instruction, the first node device may pull (pull) the OTA data packet required by the object to be upgraded from the server device of the Mesh network or the third-party server according to the identifier of the object to be upgraded. For example, the first node device may send a data request to a server device of the Mesh network or a third-party server, where the data request includes an identifier of an object to be upgraded, so as to request the server device of the Mesh network or the third-party server to obtain an OTA data packet required by the object to be upgraded; after receiving the data request, the server device or the third-party server of the Mesh network may obtain an OTA data packet required by the object to be upgraded, and return the OTA data packet to the first node device.
For another example, after sending the upgrade instruction to the first node device, the server device or the third-party server of the Mesh network may actively push the OTA data packet required by the object to be upgraded to the first node device. Based on this, the first node device may receive an OTA data packet, which is pushed by a server device of the Mesh network or a third-party server and is required by the object to be upgraded.
It should be noted that the above manner of acquiring the OTA packet required by the object to be upgraded by the first node device is not only applicable to the above embodiment, but also applicable to the following embodiments.
In an alternative embodiment, depicted in fig. 2c from the perspective of the first node device, yet another OTA upgrade method comprises:
and 21c, the first node equipment responds to the input operation to acquire an upgrading instruction input by a user, wherein the upgrading instruction comprises an identifier of an object to be upgraded and an identifier of second node equipment which is in communication connection with the object to be upgraded in the Mesh network and has direct OTA upgrading capability.
22c, the first node equipment transmits the OTA data packet to the object to be upgraded through the second node equipment according to the identification of the object to be upgraded and the identification of the second node equipment, so that the object to be upgraded is subjected to indirect OTA upgrade.
In this embodiment, the first node device has a human-computer interaction function, and when the object to be upgraded needs to be upgraded, a user can directly input an upgrade instruction to the first node device, and the upgrade instruction carries an identifier of the object to be upgraded and an identifier of the second node device. The user may be a user of the object to be upgraded, or may be a provider of the object to be upgraded.
Optionally, the first node device has a voice interaction capability, and when the object to be upgraded needs to be upgraded, the user may initiate a voice input operation and input the upgrade instruction in a voice manner. For example, a user may click a physical key on the first node device to initiate a voice input operation, or perform a touch operation on an electronic screen of the first node device to initiate the voice input operation. The first node device may acquire an upgrade instruction input by a user in a voice manner in response to a voice input operation. An example of a voice upgrade instruction is "upgrade firmware of an MCU board in a water heater through a bluetooth module in the water heater", but is not limited thereto. In this example, the bluetooth module is the second power saving device, and the MCU board is the object to be upgraded.
Optionally, the first node device is provided with an electronic screen, and a human-computer interaction interface can be provided for a user. Based on the method, a user can input an upgrading instruction to the first node device through the man-machine interaction interface. For the first node equipment, an upgrading instruction input on the human-computer interaction interface by a user can be obtained in response to the input operation on the human-computer interaction interface. For example, a user can call up an upgrade setting page through the human-computer interaction interface, and input an identifier of an object to be upgraded and an identifier of a second power saving device connected to the object to be upgraded on the upgrade setting page.
For the first node equipment, the upgrading instruction input by the user in various modes is received, the identification of the object to be upgraded and the identification of the second node equipment are analyzed from the upgrading instruction, and further the OTA data packet can be transmitted to the object to be upgraded through the second node equipment according to the identification of the object to be upgraded and the identification of the second node equipment, so that the object to be upgraded can be subjected to indirect OTA upgrading. In this embodiment, the user may store the OTA data packet for transmission of the object to be upgraded in the first node device in advance, or provide the storage address or the access path of the OTA data packet to the first node device in advance, so that the first node device can obtain the OTA data packet required by the object to be upgraded. In addition to this way, the first node device may also obtain the OTA data packet required by the object to be upgraded in other ways, see the description in the foregoing embodiment, and will not be described herein again.
In the foregoing or following embodiments of the present application, an implementation manner in which the first node device transmits the OTA data packet to the object to be upgraded through the second node device is not limited, and any implementation manner in which the OTA data packet may be transmitted to the object to be upgraded through the second node device is applicable to the embodiments of the present application. Several embodiments for transmitting the OTA data packet to the object to be upgraded via the second node device are listed below, and these embodiments are applicable to the embodiments of the present application.
In the embodiment a, the first node device directly transmits the OTA data packet required by the object to be upgraded to the object to be upgraded through the second node device according to the identifier of the object to be upgraded and the identifier of the second node device, so that the object to be upgraded is subjected to indirect OTA upgrade.
In the embodiment B, the first node device blocks the OTA packet required by the object to be upgraded according to a preset or default block size, and directly transmits the block of the OTA packet to the object to be upgraded through the second node device according to the identifier of the object to be upgraded and the identifier of the second node device, so as to allow the object to be upgraded to perform indirect OTA upgrade.
In embodiment C, the first node device obtains, through the second node device, the data version and the receiving capability information currently used by the object to be upgraded, according to the identifier of the object to be upgraded and the identifier of the second node device; and if the currently used data version of the object to be upgraded accords with the upgrading condition, partitioning the OTA data packet according to the receiving capacity information of the object to be upgraded, and transmitting the partitioned OTA data packet to the object to be upgraded through the second node equipment so as to indirectly upgrade the object to be upgraded by the OTA. If the currently used data version of the object to be upgraded does not accord with the upgrading condition, the upgrading operation is ended. The receiving capability information of the object to be upgraded represents the size of the data volume which can be received by the object to be upgraded in one data transmission.
Optionally, the first node device may compare the data version currently used by the object to be upgraded with the data version of the OTA data packet to be transmitted; if the two data versions are the same, judging that the two data versions do not meet the upgrading condition; and if the two data versions are different, judging that the upgrading conditions are met.
In embodiment C, the first node device performs upgrade verification according to the currently used data version of the object to be upgraded, and can terminate the upgrade operation in time when the upgrade condition is not met, thereby reducing unnecessary operations and saving resources.
It should be noted that, in the embodiment C, a specific embodiment of obtaining the currently used data version and the receiving capability information of the object to be upgraded by the second node device is not limited. For example, the first node device may simultaneously obtain, through the second node device, a data version and reception capability information currently used by the object to be upgraded in one communication process. For another example, the first node device may obtain, through the second node device, the data version and the receiving capability information currently used by the object to be upgraded, respectively, in a multiple communication process.
The method for respectively acquiring the currently used data version and the receiving capability information of the object to be upgraded by the second node device includes: sending a first data request to second node equipment according to the identifier of the second node equipment so as to request a data version currently used by an object to be upgraded, wherein the first data request carries the identifier of the object to be upgraded; receiving a currently used data version of an object to be upgraded returned by the second node equipment; under the condition that the currently used data version of the object to be upgraded meets the upgrading condition, a second data request is continuously sent to second node equipment to request the receiving capacity information of the object to be upgraded, and the second data request carries the identification of the object to be upgraded; and receiving the receiving capability information of the object to be upgraded returned by the second node equipment.
In an optional embodiment, in the process of blocking the OTA data packet, in addition to the receiving capability information of the object to be upgraded, the transmission capability information of the second node device may be considered. The transmission capability information of the second node device indicates the size of the data amount that the second node device can transmit in one data transmission. Of course, under the condition that the transmission capability of the second node device is strong, the OTA data packet may also be blocked according to the receiving capability information of the object to be upgraded separately.
Alternatively, the first node device may store transmission capability information of the second node device in advance. Or the first node device requests the second node device for its transmission capability information according to the identifier of the second node device. Optionally, the process of the first node device requesting the second node device for its transmission capability information may be a different process from the process of the second node device acquiring the currently used data version and the receiving capability information of the object to be upgraded. Of course, the first node device may also request the transmission capability information of the object to be upgraded from the second node device in the process of acquiring the currently used data version and the receiving capability information of the object to be upgraded by the second node device.
For example, in an optional embodiment, the first node device may send a third data request to the second node device according to the identifier of the second node device, so as to request the data version currently used by the object to be upgraded, where the third data request carries the identifier of the object to be upgraded; receiving a currently used data version of an object to be upgraded returned by the second node equipment; and under the condition that the currently used data version of the object to be upgraded meets the upgrade condition, continuously sending a fourth data request to the second node equipment to request the receiving capability information of the object to be upgraded and the transmission capability information of the second node equipment, wherein the fourth data request carries the identifier of the object to be upgraded and the identifier of the second node equipment; and receiving the receiving capability information of the object to be upgraded and the transmission capability information of the second node equipment, which are returned by the second node equipment. And then, the first node equipment blocks the OTA data packet according to the receiving capacity information of the object to be upgraded and the transmission capacity information of the second node equipment, and transmits the block of the OTA data packet to the object to be upgraded through the second node equipment so as to indirectly upgrade the object to be upgraded by the OTA.
In some optional embodiments, in the process of transmitting the blocks of the OTA packet to the object to be upgraded by the second node device, the blocks may be taken as a transmission unit, and after one block is transmitted, the next block is transmitted. Optionally, each partition has a unique number, and each partition of the OTA data packet may be transmitted to the object to be upgraded sequentially through the second node device according to the number of the partition.
Further optionally, each partition may be split into a plurality of partitions, each partition having a unique partition identification. For a block, its transmission process can be split into multiple fragmented transmission processes. For the object to be upgraded, when receiving one fragment, the second node device may return a notification message to the first node device, where the notification message may carry an identifier of the fragment successfully received by the object to be upgraded. Correspondingly, the first node device may also check whether the transmission of the current block is completed according to a notification message returned by the object to be upgraded, and start the transmission process of the next block after determining that the transmission of the current block is completed.
In some optional embodiments, the process of transmitting the chunks of the OTA data packet to the object to be upgraded by the second node device supports breakpoint resumption. For example, a first node device may monitor the presence status of a second node device; under the condition that the second node equipment is monitored to be disconnected, the transmission of the blocks of the OTA data packet to the object to be upgraded through the second node equipment is suspended, and the positions of the transmitted blocks are recorded; and after monitoring that the second node equipment is on-line again, continuously transmitting the blocks of the OTA data packet to the object to be upgraded from the recorded block positions through the second node equipment, and realizing breakpoint continuous transmission.
In the embodiments of the present application, the number of objects to be upgraded is not limited, and may be one or multiple. When there are multiple objects to be upgraded, the multiple objects to be upgraded may be objects that need to be upgraded using the same OTA data packet, or may be objects that need to be upgraded using different OTA data packets.
In the embodiment of the application, the OTA upgrading is combined with the Mesh network, and the OTA data packet can be transmitted to the object to be upgraded by means of the communication connection between the node equipment with the direct OTA upgrading capability in the Mesh network and the object to be upgraded, so that the object to be upgraded realizes indirect OTA upgrading.
It should be noted that, the present embodiment does not limit the communication technology used by the Mesh network, and the used communication technology may be flexibly selected according to the deployment requirement, so as to form the Mesh network in different communication modes. For example, in the Mesh network of the present embodiment, communication technologies such as ZigBee, Bluetooth (Bluetooth), infrared, WiFi, or NFC may be used. If the Mesh network of the embodiment of the application adopts the bluetooth communication technology, the node devices can communicate with each other based on the bluetooth protocol, so that the bluetooth Mesh network is formed.
As shown in fig. 3a, a bluetooth Mesh network provided for an exemplary embodiment of the present application includes: a plurality of bluetooth devices 301, a bluetooth gateway 302 and a server side device 303. The number of the bluetooth gateways 302 may be one or more, depending on the specific scenario and the requirement. These bluetooth devices 301 and bluetooth gateway 302 make bluetooth connections with each other; the bluetooth gateway 302 is in communication connection with a server device 303.
It should be noted that the bluetooth device 301 and the bluetooth gateway 302 in the bluetooth Mesh network may be different in implementation according to different application scenarios. In fig. 3a, taking the bluetooth Mesh network deployed in a home environment as an example, the plurality of bluetooth devices 301 includes but is not limited to: bluetooth lamp, bluetooth switch, bluetooth TV and bluetooth socket etc.. In fig. 3a, the bluetooth gateway 302 is illustrated as an example of a smart speaker, but the present invention is not limited thereto. Similarly, in fig. 3a, the server device 303 is illustrated as a cloud server, but is not limited thereto.
In the bluetooth Mesh network shown in fig. 3a, the bluetooth device 301 supports bluetooth communication and can receive data wirelessly, so that it has a direct OTA upgrade capability. Based on this, the bluetooth gateway 302 may transmit the OTA data packet to the object to be upgraded, which is communicatively connected to the bluetooth device 301, through the bluetooth device 301, so that the object to be upgraded may perform indirect OTA upgrade. The bluetooth gateway 302 corresponds to the role of the first node device in the above embodiment, and the bluetooth device 301 corresponds to the role of the second node device in the above embodiment.
As shown in fig. 3b, the process of the bluetooth gateway 302 performing indirect OTA upgrade on the object to be upgraded, which is communicatively connected with the bluetooth device 301, through the bluetooth device 301 includes the following steps:
31b, obtaining an upgrading instruction, wherein the upgrading instruction comprises an identification of an object to be upgraded and an identification of a Bluetooth device which is in communication connection with the object to be upgraded in the Bluetooth Mesh network and has a direct OTA upgrading capability.
And 32b, transmitting an OTA data packet to the object to be upgraded through the Bluetooth equipment according to the identification of the object to be upgraded and the identification of the Bluetooth equipment so as to allow the object to be upgraded to carry out indirect OTA upgrade.
The identifier of the object to be upgraded may be any information capable of uniquely identifying the object to be upgraded, and may be, for example, a name, a serial number, an IP address, an MAC address, or the like of the object to be upgraded. Accordingly, the identification of the bluetooth device may be any information capable of uniquely identifying the bluetooth device, and may be, for example, a name, a serial number, an IP address, a MAC address, or the like of the bluetooth device.
In this embodiment, the bluetooth gateway acquires the upgrade instruction, and analyzes the identifier of the object to be upgraded and the identifier of the bluetooth device in communication connection with the object to be upgraded from the upgrade instruction; and then, according to the identification of the object to be upgraded and the identification of the Bluetooth device, transmitting an OTA data packet to the object to be upgraded through the Bluetooth device in communication connection with the object to be upgraded so as to allow the object to be upgraded to carry out indirect OTA upgrade. Specifically, the bluetooth gateway may send, according to the identifier of the bluetooth device, the identifier of the object to be upgraded and the OTA data packet required by the object to be upgraded to the bluetooth device in communication connection with the object to be upgraded (i.e., the bluetooth device identified by the identifier) through a bluetooth signal, and the bluetooth device in communication connection with the object to be upgraded transmits OTA data to the object to be upgraded according to the identifier of the object to be upgraded.
Before transmitting the OTA data packet to the object to be upgraded through the bluetooth device, the bluetooth gateway may acquire the OTA data packet required by the object to be upgraded by using, but not limited to, the following methods:
in an alternative embodiment B1, the upgrade instruction carries the OTA packet required by the object to be upgraded, or the storage address or access path of the OTA packet. Based on the method, the Bluetooth gateway can analyze the OTA data packet required by the object to be upgraded from the upgrading instruction; or analyzing the storage address or the access path of the OTA data packet required by the object to be upgraded from the upgrading instruction, and acquiring the OTA data packet required by the object to be upgraded according to the analyzed storage address or the access path.
In another alternative embodiment B2, the user or the network administrator may directly store the OTA data packet required for the object to be upgraded in advance in the bluetooth gateway, or may provide the storage address or access path of the OTA data packet to the bluetooth gateway in advance. Based on the method, the Bluetooth gateway can directly obtain the OTA data packet required by the object to be upgraded from the local according to the identification of the object to be upgraded; or, locally acquiring a storage address or an access path of an OTA data packet required by the object to be upgraded, and acquiring the OTA data packet required by the object to be upgraded according to the analyzed storage address or access path. The user may be a user of the object to be upgraded, or may be a provider of the object to be upgraded.
In another alternative embodiment B3The bluetooth gateway may locally store some OTA data packets required for upgrading the objects, which may include the objects that have been upgraded before or may include the objects that have been upgraded but have not been upgraded yet. The OTA data packet locally stored by the Bluetooth gateway may or may not include the OTA data packet required by the object to be upgraded. Based on the method, the Bluetooth gateway can inquire whether the object to be upgraded is stored locally or not according to the identification of the object to be upgradedRequired OTA packets; if the OTA data packet required by the object to be upgraded is inquired locally, acquiring the OTA data packet required by the locally stored object to be upgraded; and if the OTA data packet required by the object to be upgraded is not inquired locally, acquiring the OTA data packet required by the object to be upgraded from the server-side equipment of the Mesh network or a third-party server. The third-party server corresponds to the object to be upgraded and can be responsible for providing the OTA data packet required by the object to be upgraded.
Further, for the condition that the bluetooth gateway does not inquire the OTA data packet required by the object to be upgraded locally, after the bluetooth gateway acquires the OTA data packet required by the object to be upgraded from the server device of the Mesh network or the third-party server, the bluetooth gateway can also store the OTA data packet acquired from the server device of the Mesh network or the third-party server locally, so that the OTA data can be directly acquired locally during next upgrade, network resources are saved, and upgrade efficiency is improved.
In addition to storing the OTA data packet locally in the manner described above, the bluetooth gateway may also locally cache the OTA data packet in the following manner. For example, an OTA data packet required for candidate object upgrade is pulled from a server device of the Mesh network or a third-party server, and the OTA data packet required for candidate object upgrade is stored locally; or receiving an OTA data packet required by candidate object upgrade pushed by a server device of the Mesh network or a third-party server, and storing the OTA data packet required by the candidate object upgrade locally. The candidate object is an object which needs OTA upgrading in the objects connected with the first node equipment. The object to which the first node device is connected is dynamically changing, and the candidate object is also dynamically changing.
In a further alternative embodiment a4, the OTA data packets required for the object to be upgraded are stored on the server device of the Mesh network or on a third party server. After receiving the upgrade instruction, the bluetooth gateway needs to acquire the OTA data packet required by the object to be upgraded from the server device of the Mesh network or the third-party server before transmitting the OTA data packet required by the object to be upgraded to the object to be upgraded through the second node device.
For example, after receiving the upgrade instruction, the bluetooth gateway may pull (pull) the OTA data packet required by the object to be upgraded from the server device of the Mesh network or the third-party server according to the identifier of the object to be upgraded.
For another example, after sending the upgrade instruction to the bluetooth gateway, the server device or the third-party server of the Mesh network may actively push the OTA data packet required by the object to be upgraded to the bluetooth gateway. Based on the above, the bluetooth gateway may receive the OTA data packet, which is pushed by the server device of the Mesh network or the third-party server and is required by the object to be upgraded.
For the object to be upgraded, the OTA data packet transmitted by the Bluetooth device can be received, and the local related resources are upgraded according to the OTA data packet. Optionally, if the OTA data packet is a firmware upgrade packet, the object to be upgraded may upgrade its firmware; if the OTA data package is a new edition installation package of the application software, the object to be upgraded can upgrade the corresponding application program installed by the object to be upgraded.
In this embodiment, the membership relationship between the object to be upgraded and the bluetooth Mesh network is also not limited, and the object to be upgraded may be a device, a component, a chip, or a board card in the bluetooth Mesh network, or may be a device, a component, a chip, or a board card outside the bluetooth Mesh network. In addition, in this embodiment, the OTA capability of the object to be upgraded is also not limited, and the object to be upgraded may not have the direct OTA upgrade capability, or may have the direct OTA upgrade capability.
In an application scenario, the bluetooth device 301 is a bluetooth module, and the object to be upgraded is an MCU board card without direct OTA upgrade capability in the bluetooth Mesh network.

And 44c, determining that the device to be upgraded needs to be subjected to indirect OTA upgrading through the target node device.
In this embodiment, the device to be upgraded needs to access the gateway device of the wireless network to request the OTA upgrade of the device through the server device or the third-party server. After receiving the connection request sent by the equipment to be upgraded, the gateway equipment judges whether the equipment to be upgraded has the direct OTA upgrading capability or not according to the identification of the equipment to be upgraded. And if the equipment to be upgraded does not have the direct OTA upgrading capability, determining that the indirect OTA upgrading is carried out on the equipment to be upgraded through the target node equipment, and the equipment to be upgraded does not need to be in communication connection with the server side equipment or a third-party server. If the equipment to be upgraded has the direct OTA upgrading capability, the purpose of performing indirect OTA upgrading on the equipment to be upgraded through the target node equipment is achieved by controlling the equipment to be upgraded to disable the direct OTA upgrading capability, so that the equipment to be upgraded does not need to be in communication connection with the server side equipment or a third-party server, the number of equipment for establishing communication connection with the server side equipment or the third-party server can be reduced, and the burden of the server side equipment or the third-party server is relieved.

Optionally, the gateway device may pre-store the identity of the device to be upgraded and its capability information locally. For example, a server device or a third-party server in the wireless network may provide the identification of the device to be upgraded and its capability information to the gateway device in advance. Based on this, the gateway device may locally query the capability information of the device to be upgraded according to the identifier of the device to be upgraded.
Optionally, the gateway device may also send a capability information acquisition request to the server device or the third-party server in the wireless network according to the identifier of the device to be upgraded, so as to request the server device or the third-party server to return the capability information of the device to be upgraded.

In the embodiment of the present application, an implementation manner of determining a device to be upgraded from devices provided by a third party is not limited. For example, the upgrade management device may provide various upgrade services to a third party, and the third party may select a corresponding upgrade service; the upgrade management device determines the implementation mode of the device to be upgraded from the devices provided by the third party, wherein the upgrade services selected by the third party are different. The following examples illustrate:
in an alternative embodiment, the upgrade management device may contract an upgrade management policy with a third party. The third party may make a relevant agreement in the upgrade management policy for the device that needs to be upgraded. Based on this, the upgrade management device may determine the device to be upgraded from the devices provided by the third party according to the upgrade management policy agreed with the third party.
For example, a third party may agree on an upgrade period for all devices in an upgrade management policy, such as an upgrade every three months. Based on this, the upgrade management device may use all devices provided by the third party as the devices to be upgraded when the upgrade period agreed in the upgrade management policy arrives according to the upgrade management policy agreed with the third party.
As another example, a third party may agree on an update period for firmware and/or software for each device in an upgrade management policy, such as device A's firmware being updated every half year, device A's software being updated every three months, device B's firmware being updated every month, and so forth. Based on this, the upgrade management device may determine, from the devices provided by the third party, the device at which the update cycle of the firmware and/or software arrives, that is, the device that needs to update the firmware and/or software, as the device to be upgraded, according to the update cycle of the firmware and/or software of each device included in the upgrade management policy agreed with the third party.
For another example, the third party may perform upgrade management on the devices according to device batches, and based on this, the upgrade time of each batch of devices may be agreed in the upgrade management policy, for example, the first batch of devices is upgraded in 10 months and 20 days, the second batch of devices is upgraded in 11 months and 20 days, and so on. Based on this, the upgrade management device may determine, from the devices provided by the third party, a batch of devices at which the upgrade time arrives as the devices to be upgraded, according to the upgrade time of each batch of devices included in the upgrade management policy agreed with the third party.
In another alternative embodiment, the upgrade management device may provide a real-time upgrade service to a third party. Based on the method, the third party can send an upgrading request to the upgrading management equipment at any time as required so as to request the upgrading management equipment to upgrade and manage the corresponding equipment. Based on this, the upgrade management device may receive an upgrade request provided by a third party, where the upgrade request carries a device identifier that needs to be upgraded; according to the device identifier to be upgraded carried in the upgrade request, determining a device to be upgraded from devices provided by a third party, as shown in fig. 4 e.
The upgrade management device may support multiple upgrade modes. The upgrade method herein may include but is not limited to: a direct OTA upgrade mode, an indirect OTA upgrade mode, an infrared upgrade mode, a Bluetooth upgrade mode and the like. In addition, the upgrading mode can be flexibly defined according to the application requirements. These upgrading modes have a certain relationship with the type and/or function of the device to be upgraded. For example, for a device without direct OTA upgrade capability, only an indirect OTA upgrade mode can be adopted; for the device with the direct OTA upgrading capability, a direct OTA upgrading mode can be adopted, an indirect OTA upgrading mode can be adopted, and the upgrading method can be determined according to an upgrading strategy or the requirements of a third party. The upgrade management device may determine an upgrade mode of the device to be upgraded according to the type and/or function of the device to be upgraded. And then, upgrading the equipment to be upgraded according to the determined upgrading mode.
In this embodiment, the upgrade management device is mainly responsible for performing upgrade management, for example, determining a device to be upgraded, determining an upgrade mode of the device to be upgraded, and controlling the device to be upgraded to perform upgrade according to the upgrade mode.

If the upgrading mode is a direct OTA upgrading mode, the process of controlling the equipment to be upgraded to upgrade according to the upgrading data comprises the following steps: and the upgrade management equipment directly transmits the upgrade data to the equipment to be upgraded so as to carry out direct OTA upgrade on the equipment to be upgraded.
Further, in an application scenario in which the upgrade management device upgrades the device to be upgraded, the upgrade management device may further provide, to a third party, upgrade detail information of the device to be upgraded, where the upgrade detail information at least includes upgrade progress information and upgrade result information.
In another application scenario, a third party chooses to use its own server to actually upgrade the device to be upgraded. In the application scenario, an implementation manner in which the upgrade management device controls the device to be upgraded to perform upgrading according to the upgrade manner includes: and sending an upgrade notification to a server of the third party, wherein the upgrade notification comprises an identifier of the equipment to be upgraded and description information of the upgrade mode, so as to notify the server of the third party to upgrade the equipment to be upgraded by using upgrade data required by the equipment to be upgraded according to the upgrade mode. The description information of the upgrade mode may uniquely determine the upgrade mode, and may be, for example, an identifier, a name, or simple explanatory information of the upgrade mode. The third-party server may refer to the implementation process of the upgrade management device for upgrading the device to be upgraded according to the upgrade mode and the upgrade data required by the device to be upgraded, and is not described herein again.
In any application scenario, the upgrade management device may monitor the running state information of the device provided by the third party and report the monitored running state information to the server of the third party, in addition to providing the upgrade management service for the third party. The operation state information may include any information related to the operation state of the device, such as the number of times the device is turned on and off, the duration of each operation, the total duration of the operation, the time and number of times it is down, the CPU power consumption and utilization, the memory power consumption and utilization, and so on. Based on this, the third party can see the running state information of the equipment, so that on one hand, the performance, the existing defects and the like of the equipment can be known, and the improvement or the update iteration of the equipment can be facilitated.
Certainly, the upgrade management device may also count information such as the remaining duration and the remaining cost of the third party using the upgrade management service, and feed the information back to the third party in time, so that the third party can continue to apply for or purchase the upgrade management service.
