1. What is the AT command AT command is used for controlling module. You can use AT command to configure and query the settings. 2. How to use the AT command For USR device is in transparent mode normally, you must enter AT command mode at first. Then you can send AT command to configure or query the settings. After you configure the USR device, you should restart the USR device to make the settings take effect. Every time module restart will work in work mode rather AT command mode. Every AT command must add character carriage return <CR> and line feed <LF>. In Hex, <CR> is 0x0D <LF> is 0x0A. 2.1. How to enter AT command mode Please read this FAQ about entering AT command mode. https://www.usriot.com/support/faq/enter-serial-command-mode.html 3. AT command set For more WH-BLE102 AT Command Set, please click: https://www.usriot.com/support/downloads/wh-ble102-at-command-set_V100.html

Serial device Server has been increasingly employed in industrial fields, and in some application situations, its parameters should be set. There are several ways to set the serial device server parameter as follows. General parameter of serial device server can be set through the website or AT command. First, set on the website. Setting on website is the most common way. Routers at home are also set on website, so most people are familiar with it. First, open browser, and input ip address of serial device server which is generally on the server in the address bar. Then, login-in page will open. Input registration account and password to enter to modify parameters. The advantage of setting on the website is its simplicity, that is, it can be handled with the browser on the computer without any extra supporting devices. However, please ensure that the address of the serial device server is in the same segment with the computer. Second, set through AT command. AT com...

What are the environmental requirements for the installation of  cellular routers ? Installation of cellular routers usually has no special requirements and can be placed on walls or tables in any space. But in order to ensure the best performance of cellular routers, it is better to choose a suitable place. For the installation of cellular routers, it is best to meet the following points: 1. Place  cellular  routers horizontally, as high as possible and as centered as possible (relatively close to PC). 2. Try to keep the antenna upright. 3. Do not place  cellular  routers in a damp place. 4. In order to get better reception effect, do not put the  cellular  router in the corner. 5. Keep away from possible sources of interference, such as metal partitions, high-power electrical appliances, etc. Establish connection Before connecting the  cellular  router, please first confirm that the power of the  cellular ...

1. Manufacturing supply chain management: Enterprises can use IoT technology to grasp the information of raw material procurement, inventory, sales, etc., and predict the price trend of supply materials, supply and demand, etc. through big data analysis, which helps to perfect and optimize the supply chain management system, improve supply chain efficiency and reduce costs. Airbus builds the largest and most efficient supply chain system in the global manufacturing industry by applying sensor network technology in the supply chain system. 2. Process optimization in the production process: The ubiquitous sensing characteristics of the industrial Internet of Things improve the ability and level of process line detection, real-time parameter acquisition, and material consumption monitoring, realize intelligent monitoring, intelligent control, intelligent diagnosis, intelligent decision making and intelligent maintenance, increase productivity and reduce energy consumption through...

In the era of 5G, the Internet of everything comes into being. The frequency band used by the 150M router is 2.4HZ, and 5G is 5HZ, which is commonly known as gigabit wireless router. In comparison, the 5G frequency band has the advantages of stronger anti-interference, more stable signal, wider coverage, and the higher bottleneck of data transmission. So what are the requirements for 5G industrial routers? What are the requirements for  industrial 5G routers ? First: Normativeness of communication interfaces In the process of designing industrial-grade 5G routers, designers need to standardize the communication interface between the modular structures of the equipment. The maintenance and update of industrial-grade 5G router modules and the addition of new modules should not affect other communication modules of the components. In addition, industrial 5G router software should have a high fault tolerance capacity, so that generally small software failures should not cause ...

There are two kinds of  GPRS modems  that produced by USRIOT which are USR-GPRS232–730 and USR-GPRS232–734. USR-GPRS232–730 is an RS232/RS485 Serial to GSM GPRS Modem, while USR-GPRS232–734 is an RS485 industrial cellular modem or RS485 serial GSM modem. Except they have different serial ports, but the features of USR-GPRS232–730 and USR-GPRS232–734 are mainly the same, the following are their features: 1.Support GSM850/900 DCS1800/1900 2.Support Httpd Client 3.Support GSM/GPRS and 2G/3G/4G card, but don’t support 3G/4G network 4.Support SMS transmission mode, network transmission mode and HTTPD mode USRIOT’s GPRS modem is ensured because USRIOT’s products have acquired CCC, CE, and other Necessary certifications. The price of USRIOT’s GPRS modem is also affordable. The price of USR-GPRS232–730 is $29.00. The price of USR-GPRS232–734 is $35.00.

The main difference between the industrial 3G router and the  industrial 4G router  is that the embedded module is different, the 3G module is embedded in the industrial 3G router, and the 4G router uses the 4G LTE network. The difference between the two modules is also the difference between 3G and 4G networks, so we look at the difference between the two from the development history of 3/4G. Technically, there are many differences between third-generation (3G) network and fourth-generation (4G) network (also known as LTE (Long Term Evolution) network). In order to understand their operations, I will start from the first generation (G) network to LTE. In addition, I will try to describe every term I use, or rather, avoid them. Prior to the advent of 3G or 4G networks, the first generation (G) network was the first network discovered and put into use in the United States in the early 1980s. The transmission of this network is similar. The principle is to use FDMA ...

A common router uses a frequency range of 2.4hz, while 5G router uses a frequency range of 5HZ, which is commonly a gigabit wireless router. In contrast, the frequency band of 5G has advantages such as stronger anti-jamming, more stable signals, wider coverage, and higher data transmission bottlenecks. This article reveals the powerful features of 5G industrial routers Features of 5G routers 1. Good anti-interference performance The 5G frequency band has a high signal, which has a great impact on the penetration of walls, resulting in a small interference between routers. Moreover, the signal is very stable. 2. Fast transmission speed If you use 100MB broadband, the router is under 5G, the measured network speed of 5G industrial router can reach 10MB per second, while the download speed of 2.4G industrial router was 4 to 6 trillion per second. Of course, it depends on the broadband of your place. 3. Requirements for receiving and transmitting equipment For example, some ...

How  industrial router  limited the data speed? Limited the data speed is a basic function of the industrial router, but how industrial router limited the data speeds? QoS（Quality of Service）is a secure technology which used to solve network latency and congestion.   Technically, when network is only used for a specific, un-time-limited application such as Web applications, or E-mail application, QoS is not required. But QoS is necessary when the network is used for key applications and multimedia applications. When the jam of network happens, all the data flow may be discarded, but QoS can ensure the important data flow is not delayed or discarded and meanwhile can ensure the efficient transmission of the network.   USRIOT’s  industrial router  with QoS function can provide high-performance transmission service.
