Generally speaking, we call the implementation code of a certain protocol a protocol stack. The Bluetooth protocol stack is the code that implements the low-power Bluetooth protocol. Understanding and mastering the Bluetooth protocol is a prerequisite for implementing the Bluetooth protocol stack. The Bluetooth protocol

This paper describes the interference phenomenon caused by using relays to control power loads in electronic circuits, analyzes the mechanism of interference and proposes solutions. The study found that the interference comes from spatial coupling, and the interference source is the spark generated by the

BLE is a low-power Bluetooth technology that can effectively reduce the power consumption of Bluetooth devices and increase the operating time of the device. But even the same BLE device will produce different power consumption rates under different usage conditions. So what exactly affects the

On September 12, 2019, Japan’s Environment Minister advocated that Fukushima nuclear wastewater be discharged into the sea Japan postpones decision to discharge Fukushima nuclear wastewater into the sea on October 24, 2020 Japan’s nuclear wastewater reserves are about to reach their limit on March 4,

As an execution amplification and expansion component of signal output, the intermediate relay plays an important role in the automatic control system. According to the regulations of the equipment periodic inspection system, necessary inspections and tests should be carried out regularly on the working status

With the continuous development and maturity of sensors, wireless data transmission equipment, and application solutions, they are also constantly promoting the development of industrial applications, smart homes, smart security, smart transportation, smart environmental protection, smart agriculture and other industries; recently, many foreign apparel companies have

We should all know about antennas. Any radio communication system is inseparable from the composition of antennas. We all know that antennas are used to radiate and receive electromagnetic waves. Antennas can make a wireless transceiver device receive and transmit stronger signals. What principle is

What is a VPN? VPN (Virtual Private Network) is a well-known abbreviation among regular Internet users. Initially, VPNs were used in enterprises to connect networks securely. Currently, VPN is used by the industrial IoT industry to encrypt data transmission environments. For example, industrial routers generally

Industrial routers generally have higher stability than civilian wireless routers on the market, and they need to adapt to continuous operation in harsh weather conditions, and the cost is also higher. Nowadays, they are widely used in M2M industries in the Internet of Things industry

We have analyzed the factors that affect the antenna transmission distance before. In fact, the antenna gain also has a very large impact on the transmission distance. So, is the higher the antenna gain, the better? Once you understand the concept of gain and the

With the continuous development of electronics, oscillator circuits have been widely used in various instruments and equipment as an extremely useful functional circuit, and then entered various fields such as wireless communications. Today, we will talk about the 555 oscillator using an LED flash circuit

The radio frequency signal amplifier (RF PA) is an important part of the transmission system, and its importance is obvious. What is a radio frequency signal amplifier? The following gives us a brief introduction to the concept of RF signal amplifiers and the classification of
