These drawings and the written description are not intended to limit the scope of the inventive concepts in any way, but to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments.
Detailed Description
For the purposes of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application, and it is apparent that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Fig. 1 is a schematic diagram of an application scenario of a wireless communication module. As shown in fig. 1, the upper computer may send instruction information for instructing the wireless communication module to establish a communication connection between the upper computer and a server corresponding to the upper computer to the routing module of the wireless communication module. After receiving the instruction information, the routing module in the wireless communication module can use the acquired IP address to establish communication connection between the upper computer and the server corresponding to the upper computer, so that data transmission can be carried out between the upper computer and the server through the communication connection.
The upper computer may be any electronic device capable of controlling the wireless communication module to establish communication connection between the upper computer and other devices through an instruction. The upper computer may be, for example, a central processing unit (Central Processing Unit, CPU) of an electronic device such as a tablet computer, a notebook computer, a mobile phone, or an electronic device such as a video camera, a desktop computer, a micro control unit (Microcontroller Unit, MCU).
For example, taking the upper computer as a desktop computer, the desktop computer can send the instruction information to the wireless communication module through the communication interface. The communication interface may be integrated in the upper computer or may be an entity device independent of the upper computer. The communication interface may be, for example, a universal serial bus (Universal Serial Bus, USB) interface. The wireless communication module may be, for example, a wireless network card. In this example, the server corresponding to the upper computer may be, for example, a World Wide Web (Web) application server, or a server corresponding to application software installed in the upper computer.
Taking the above-mentioned upper computer as the CPU of the mobile phone or tablet computer as an example, the upper computer and the wireless communication module shown in fig. 1 may be both integrated in the mobile phone or tablet computer. In this example, the server corresponding to the upper computer may be, for example, a server corresponding to an Application (APP) installed in a mobile phone or a tablet computer.
Taking the upper computer as a camera as an example, the server corresponding to the upper computer may be a background server corresponding to the camera, for example. The video camera can be connected with the background server through communication established by the wireless communication module, and the video collected by the video camera is sent to the background server. The backend server may then output the video to a display device for viewing by the user.
It should be understood that the present application is not limited to the wireless communication manner that the wireless communication module can implement. For example, as shown in fig. 1, the wireless communication module may implement a server corresponding to the upper computer through a wide area network (Wide Area Network, WAN) interface, or the FOTA upgrade server may perform communication connection. Furthermore, it should be understood that fig. 1 is only an exemplary illustration of modules related to the present application in a wireless communication module, and the present application is not limited to whether the wireless communication module further includes other modules.
The wireless communication module is also provided with a FOTA module. The FOTA module can be used for realizing firmware upgrade of the wireless communication module so as to perfect the functions of the wireless communication module. When the firmware of the wireless communication module is upgraded, the wireless communication module also needs an IP address to establish communication connection between the wireless communication module and the FOTA upgrading server, so as to obtain the FOTA upgrading packet.
At present, the wireless communication method for acquiring the FOTA upgrade package by the wireless communication module mainly comprises the following two steps:
firstly, the wireless communication module needs to disconnect the communication connection between the servers corresponding to the upper computer. Then, a new IP address is acquired, and a communication connection with the FOTA upgrade server is established using the new IP address. Through the communication connection with the FOTA upgrading server, the wireless communication module can acquire the FOTA upgrading packet.
That is, the wireless communication module needs to use one IP address to establish a communication connection with the server corresponding to the upper computer, and use another IP address to establish a communication connection with the FOTA upgrade server, and the two communication connections cannot exist at the same time.
With this wireless communication method, two communication connections cannot exist at the same time. That is, the wireless communication module can only maintain one wireless communication connection at a time. For example, taking the case that the wireless communication module maintains the communication connection with the FOTA server, the wireless communication module disconnects the communication connection between the servers corresponding to the upper computer, which results in that data transmission between the upper computer and the servers corresponding to the upper computer cannot be performed. Still take the above-mentioned host computer as the camera for example, if the wireless communication module breaks and establishes communication connection between the backstage servers corresponding to the camera, the video collected by the camera can not be transmitted to the backstage servers. Therefore, the method makes the transmission efficiency of the wireless communication module lower. In addition, in the method, the wireless communication module occupies two IP addresses, so that more network resources are occupied.
Second, the wireless communication module can use two different IP addresses to respectively establish communication connection between servers corresponding to the upper computer and communication connection between the servers and the FOTA upgrading server.
Although the method can realize data transmission between the upper computer and one device, the wireless communication module can also realize data transmission with the other device. In reality, however, most wireless communication modules can only provide one IP address at a time. That is, this method is not applicable to most wireless communication modules that cannot use two IP addresses at the same time. In addition, in the method, the wireless communication module occupies two IP addresses, so that more network resources are occupied.
In view of the above problems of the existing wireless communication method, the present application proposes a method that can realize data transmission between an upper computer and one device without using two addresses, and at the same time, the wireless communication module can also perform data transmission with another device. Compared with the existing method, the wireless communication method provided by the application does not need to use two addresses, is suitable for most wireless communication modules, ensures that data transmission can be performed between an upper computer and one device, and meanwhile, the wireless communication module can also perform data transmission with the other device, so that the transmission efficiency of the wireless communication module is improved. Meanwhile, the method can also save network resources.
In particular, the main execution body of the method is a wireless communication module.
The technical scheme of the present application will be described in detail with reference to specific embodiments. The following embodiments may be combined with each other, and some embodiments may not be repeated for the same or similar concepts or processes.
Fig. 2 is a flow chart of a wireless communication method provided in the present application. As shown in fig. 2, the method comprises the steps of:
s101, determining whether the wireless communication module currently has an established first wireless communication connection. If yes, step S102 is executed. If not, the wireless communication module may optionally execute step S104.
S102, establishing a second wireless communication connection with the second device by using an address used when the first wireless communication connection is established.
S103, performing wireless communication with the first device by using the first wireless communication connection and performing wireless communication with the second device by using the second wireless communication connection.
S104, acquiring an address used for establishing a second wireless communication connection with the second device.
S105, using the address, establishing a second wireless communication connection with the second device.
S106, using the second wireless communication connection, performing wireless communication with the second device.
The first wireless communication connection is a communication connection between the wireless communication module and the first device.
In one possible implementation manner, the first wireless communication connection may be used to transmit communication data between the upper computer and the first device, and the second wireless communication connection may be used to transmit communication data between the wireless communication module and the second device.
In this implementation manner, the first device may be a server corresponding to the upper computer, or other electronic devices capable of establishing wireless communication connection with the wireless communication module. For example, if the upper computer is a camera, the first device may be a background server corresponding to the camera, or other cameras, etc. The second device may be an FOTA upgrade server, or an electronic device storing an "FOTA upgrade package" required for FOTA upgrade by the wireless communication module.
In another possible implementation manner, the first wireless communication connection may also be used to transmit communication data between the wireless communication module and the first device, and the second wireless communication connection is used to transmit communication data between the upper computer and the second device.
In this implementation manner, the first device may be an FOTA upgrade server, or an electronic device storing an "FOTA upgrade package" required for FOTA upgrade by the wireless communication module. The second device may be a server corresponding to the upper computer, or other electronic devices capable of establishing wireless communication connection with the wireless communication module. For example, if the upper computer is a camera, the second device may be a background server corresponding to the camera, or other cameras, etc.
Optionally, after the first communication connection is established with the first device, the wireless communication module may generate an identification for indicating that the wireless communication has the first wireless communication connection established. The wireless communication module may determine whether the wireless communication module currently has an established first wireless communication connection by detecting whether the wireless communication module has the identification. If the wireless communication module is detected to have the identifier, the wireless communication module can be determined to have the established first wireless communication connection. If the wireless communication module is detected to not have the identifier, the wireless communication module can be determined to not have the established first wireless communication connection.
Alternatively, if the first communication connection is established between the wireless communication module and the first device, the core network device may send an identifier to the wireless communication module indicating that the wireless communication has the established first wireless communication connection. Accordingly, the wireless communication module may determine whether the wireless communication module currently has an established first wireless communication connection according to whether the identification is received. If the wireless communication module receives the identification, it may be determined that the wireless communication module has an established first wireless communication connection. If the wireless communication module does not receive the identification, it may be determined that the wireless communication module does not have the established first wireless communication connection.
It should be understood that the present application is not limited to the form of the above-described identification for indicating that the wireless communication exists with the established first wireless communication connection. The identification may be, for example, a specific numerical value (e.g., number 1), or a specific combination of letters, or a specific file, etc.
The address used when the first wireless communication connection is established may be, for example, an IP address obtained by the wireless communication module from the core network device. Alternatively, the address may be, for example, an identifier that can represent unique identity information of the wireless communication module, such as a media access control layer (Media Access Control, MAC) address, or the like.
Optionally, the wireless communication module may establish the second wireless communication connection with the second device according to the "wireless connection parameters required for establishing the second wireless communication connection with the second device" and the address used when the first wireless communication connection is established. Optionally, the wireless connection parameters may be stored in the wireless communication module in advance by the user. Alternatively, the wireless communication module may also receive wireless connection parameters input by the user. The wireless connection parameters may include, for example, parameters such as an access point name (Access Point Name, APN), IP version type (e.g., IPv4 or IPv 6), and the like.
It should be understood that the present application is not limited to how the wireless communication module establishes the second wireless communication connection with the second device using the address used when establishing the first wireless communication connection. In particular, the wireless communication module may use the address to establish a second wireless communication connection with the second device, for example, by way of network driver interface specification (Network Driver Interface Specification, NDIS) dialing, network sharing (telephoting) dialing, or the like.
Taking the first device as a server corresponding to the upper computer and the second device as an FOTA upgrade server as an example, the wireless communication module may use the first wireless communication connection to send information of the upper computer to the server corresponding to the upper computer, and send information of the server corresponding to the upper computer. When the wireless communication between the upper computer and the server corresponding to the upper computer is realized, the wireless communication module can use the second wireless communication connection to send the identification information of the wireless communication module to the FOTA upgrading server, and then the FOTA upgrading packet for upgrading the wireless communication module is obtained from the FOTA upgrading server.
If it is determined that the wireless communication module currently does not have the established first wireless communication connection, the wireless communication module may acquire an address used to establish the second wireless communication connection with the second device. The address may be an IP address, for example. In this example, the wireless communication module may obtain, from the core network device, an IP address used to establish the second wireless communication connection with the second device.
The wireless communication module may then establish a second wireless communication connection with the second device using the address. And then using the established second wireless communication connection to perform wireless communication with the second device.
In this embodiment, after determining that the wireless communication module has established the first wireless communication connection with the first device, a second wireless communication connection with the second device is established by using an address used when the first wireless communication connection is established. The wireless communication module may then wirelessly communicate with the first device using the first wireless communication connection and with the second device using the second wireless communication connection. The first wireless communication connection and the second wireless communication connection can be established without using two addresses by the method, so that the data transmission between the upper computer and one device is ensured, and the wireless communication module can also perform data transmission with the other device. Furthermore, compared with the existing method for respectively establishing the first wireless communication connection and the second wireless communication connection through two addresses, the method for establishing the first wireless communication connection and the second wireless communication connection by using only one address reduces waste of network resources.
The following describes in detail how the wireless communication module uses the first wireless communication connection to wirelessly communicate with the first device and uses the second wireless communication connection to wirelessly communicate with the second device. As a possible implementation manner, the foregoing step S103 may include the following steps:
step 1, determining whether target data is received based on the first wireless communication connection or the second wireless communication connection. If yes, go to step 2. If not, optionally, the wireless communication module may continue to maintain the first wireless communication connection and the second wireless communication connection to continue to acquire the target data.
In the following, taking as an example that the first wireless communication connection is used for transmitting communication data between the upper computer and the first device and the second wireless communication connection is used for transmitting communication data between the wireless communication module and the second device, it is exemplified how to determine whether the target data is received based on the first wireless communication connection or the second wireless communication connection.
For example, taking the first device as a server corresponding to the upper computer as an example, the server corresponding to the upper computer may send, after sending the target data to the wireless communication module, an identifier for indicating that the transmission of the target data is completed to the wireless communication module. Accordingly, the wireless communication module can determine whether to complete receiving the target data according to whether the identification is received.
Taking the second device as an FOTA upgrade server as an example, if the wireless communication module receives the FOTA upgrade packet, it may be determined that the target data is received. If the FOTA upgrade package is not received, it may be determined that the target data is not received.
And step 2, determining a receiving object of the target data according to the source address information of the target data. Wherein the receiving object is a wireless communication module or an upper computer. The source address information is used for indicating the source of the target data, and the source address information of the target data sent by different devices is different. The target data may carry the source address information.
For example, if the source address information of the target data indicates that the target data is sent by the server corresponding to the upper computer, the wireless communication module may determine that the receiving object of the target data is the upper computer. If the source address information of the target data indicates that the target data is sent by the FOTA application server, the wireless communication module may determine that the receiving object of the target data is the wireless communication module.
If the object of receiving the target data is determined to be an upper computer, the wireless communication module sends the target data to the upper computer. Or if the receiving object of the target data is determined to be a wireless communication module, the wireless communication module can decode the target data. In the implementation manner, the FOTA upgrading module of the wireless communication module can decode the target data and write the target data into the target partition, so that the wireless communication module is upgraded. The target partition may be, for example, a flash partition of a wireless communication module.
As a possible implementation manner, taking the above second wireless communication connection for transmitting communication data between the upper computer and the second device as an example, before determining whether the wireless communication module currently has the established first wireless communication connection, the wireless communication module may further receive a wireless communication connection instruction sent by the upper computer. Wherein the wireless communication connection instruction is for requesting to establish a wireless communication connection with the second device. The wireless communication connection instruction may be, for example, an Attention (AT) instruction.
In this implementation manner, by taking the upper computer as an example of a CPU of the mobile phone, the wireless communication module in the mobile phone may receive an AT instruction sent by the CPU. After receiving the AT command, the wireless communication module determines whether an established first wireless communication connection currently exists.
In another possible implementation, the wireless communication module may need to be firmware upgraded after it has been used for a predetermined period of time. Therefore, the wireless communication module can determine whether the wireless communication module currently has the established first wireless communication connection after the preset time period is reached when the wireless communication module is used. And then, referring to the method described in the previous embodiments, the FOTA upgrade package of the wireless communication module is obtained.
As a possible implementation, the wireless communication module may further store wireless connection parameters used when establishing the second wireless communication connection with the second device after establishing the second wireless communication connection with the second device using the address used when establishing the first wireless communication connection. For example, the wireless communication module may store the wireless connection parameters in a non-volatile memory (NVRAM), so that the wireless connection parameters are not lost even if the wireless communication module is powered down, thereby improving the security of storing the wireless connection parameters.
In this embodiment, by storing the wireless connection parameter used when the second wireless communication connection is established with the second device, the wireless connection parameter can be directly invoked when the next wireless communication module establishes the second wireless communication connection with the second device, so that the user is prevented from setting the wireless communication parameter when the wireless communication module establishes the second wireless communication connection with the second device, the communication efficiency of the wireless communication module is improved, and the user experience is improved.
Still taking the example that the first wireless communication connection is used for transmitting communication data between the upper computer and the first device, and the second wireless communication connection is used for transmitting communication data between the wireless communication module and the second device, it is assumed that the first device is a server corresponding to the upper computer, and the second device is an FOTA upgrade server, in this example, fig. 3 is a flow chart of another wireless communication method provided in the present application.
As shown in fig. 3, the method comprises the steps of:
s201, receiving an AT command sent by an upper computer.
The AT instruction is for requesting a wireless communication connection to be established with the FOTA upgrade server.
S202, determining whether the wireless communication module currently has an established first wireless communication connection.
If yes, go to step S203. If not, step S208 is performed.
S203, using the IP address used when the first wireless communication connection is established, establishing a second wireless communication connection with the FOTA upgrading server through an NDIS dialing mode.
S204, performing wireless communication with a server corresponding to the upper computer by using the first wireless communication connection, and performing wireless communication with the FOTA upgrading server by using the second wireless communication connection so as to obtain the FOTA upgrading packet.
S205, determining whether target data is received based on the first wireless communication connection and target data is received based on the second wireless communication connection. If yes, go to step S206. If not, step 207 is performed.
S206, disconnecting the NDIS dialing.
S207, maintaining wireless communication connection with unfinished target data transmission; the wireless communication connection for which the target data transmission has been completed is deactivated.
