4G LTE Modem USR-G780 V2 Network AT Command Remote Modification of 4G LTE Modem Parameter Settings

PublishTime： 2024-08-07 Article Source：usr Official Website

In the wave of IIoT, 4g lte modem is a key component for connecting remote devices and data centers, and its stability and flexibility are crucial. USR-G780 V2, as a high-performance 4g lte modem device, not only supports multiple communication protocols and interfaces, but also has the advanced function of remotely modifying parameters through network AT commands. This function is particularly important for application scenarios that require frequent configuration adjustments or remote management. This article will explore how to use network AT commands to remotely modify the parameter settings of USR-G780 V2 4g lte modem, bringing unprecedented convenience and efficiency to traditional industries.

I. Overview of Network AT Commands

The network AT command is a method of sending control commands to the 4g lte modem through a network interface. It allows users to remotely query and set various parameters of the 4g lte modem without physical contact with the device. The network AT command format supported by the USR-G780 V2 is usually "command password + AT command", where the command password is used to verify the user's identity and ensure the legitimacy and security of the command.

II. Steps for Remotely Modifying 4g Lte Modem Parameters

1. Establish network connection: First, ensure that the USR-G780 V2 4g lte modem is connected to the Internet and has a valid IP address and port number. Also, set up a network debugging assistant or corresponding management software on the remote server to send and receive AT commands.

2.Send AT command: Send network AT commands to the USR-G780 V2 4g lte modem through a remote server. Taking the query of the 4g lte modem firmware version as an example, you can send the command "adminAT+VER?", where "admin" is the default command password and "AT+VER?" is the AT command to query the firmware version. Note that the end of the AT command must include a semicolon and a carriage return in English.

3.Receive response: After receiving the AT command, 4g lte modem will perform the corresponding operation and return the response information. For example, for the "adminAT+VER?" command, 4g lte modem will return its firmware version number as a response.

4.Modify 4g lte modem parameters: If you need to modify the parameters of the 4g lte modem, you can send the corresponding setting instructions. Taking the modification of the SOCKA parameter as an example, you can send the instruction "adminAT+SOCKA=TCP,clouddata.usr.cn,15000" to set the SOCKA communication protocol to TCP, the server address to clouddata.usr.cn, and the port number to 15000. Please note that the modified parameters usually need to be restarted by the 4g lte modem to take effect, so you need to send the "adminAT+Z" instruction to restart the device at the end.

III. Combination of Edge Computing and Parameter Optimization

During the process of remotely modifying 4g lte modem parameters, combining edge computing capabilities can further improve system performance and efficiency. For example, by deploying edge computing nodes on 4g lte modem, local preprocessing and analysis of data can be realized, reducing data transmission volume, lowering network latency, and protecting data privacy. At the same time, edge computing can also dynamically adjust 4g lte modem parameter settings based on real-time data to optimize network connectivity and data transmission efficiency.

IV. Application Scenario Examples

The USR-G780 V2 4g lte modem, with its ability to remotely modify parameters using network AT commands, plays an important role in multiple application scenarios. For example, in the field of intelligent manufacturing, it can achieve real-time monitoring and dynamic adjustment of production lines by remotely modifying 4g lte modem parameters; in the field of intelligent transportation, it can remotely adjust the parameters of traffic monitoring equipment to cope with different traffic conditions; in remote monitoring systems, it can modify the communication protocol and server address of 4g lte modem in real time to adapt to different network environments.

The USR-G780 V2 4g lte modem, with its ability to remotely modify parameters through the support of network AT commands, brings unprecedented convenience and flexibility to traditional industries. Whether it is querying device status, modifying communication parameters, or optimizing network connectivity, it can be easily achieved through the network. At the same time, combined with edge computing capabilities, it can further improve the performance and efficiency of the system, promoting the in-depth development and wide application of industrial IoT. As senior engineers in industrial IoT, we should actively master and apply these advanced technologies to contribute wisdom and strength to the digital transformation of traditional industries.
