LPWA communication technology 2020-06-15 16:02:38 Azir 9 Traditional wireless communication technology includes two categories: cellular mobile communication and short-range wireless communication technology. However, with the development of the Internet of Things, LPWA communication technology has emerged that is consistent with the demands of many Internet

In the past few years, mobile broadband has developed rapidly and has covered more than 2 billion customers. More and more people, organizations and institutions have joined the fully connected world. In the fully connected world, except for the most important people, we We have

Internet of Things, abbreviated as IoT, is an important part of the latest generation of information technology and an important development stage in the “information age”. The Internet of Things is widely used in the integration of networks through communication sensing technologies such as intelligent

Anyone who has been in contact with the Internet of Things should often hear this word – baud rate. For engineers, this must be very familiar, but for students who are just beginning to understand the Internet of Things, it is relatively unfamiliar. Let’s clear

The difference between embedded and microcontroller development models The difference between development models Single-chip microcomputer: Most of the development is bare metal, the program size is small, and most are independently developed by a single programmer. Some complex products also use high-end microcontrollers such as

I. Introduction 1.1 Scope MODBUS is an application layer messaging protocol on layer 7 of the OSI model that provides client/server communication between devices connected to different types of buses or networks. Since its emergence in 1979 as the de facto standard for industrial serial

Everyone has always heard about the major features of NB-ioT, including ultra-low cost, ultra-low power consumption, ultra-strong coverage, and ultra-large connections. It is estimated that some people are a little confused about the concept of this feature, and there is no detailed explanation of these

What is a watchdog Watchdog (watch dog timer watchdog timer). What is a watchdog ? Let’s imagine this scenario: There is a dog at the door of your house. This dog will be hungry at regular intervals (for example, every 2 hours). When the dog

Niubility technology in NB-IoT 2020-05-27 17:15:05 Azir 17 NB-ioT technology has always attracted much attention. What are the key features that make it so popular? (Super coverage, ultra-low cost, ultra-low power consumption, ultra-large connection, SC-FDMA, OFDMA) Behind these characteristics , and what technologies it includes,

“C Runtime” requires certain conditions, which are provided by assembly. The c language mainly requires a stack when running The relationship between C language and stack: Local variables in C language are all implemented using the stack. If our assembly part does not pre-set a
