1. IntroductionBLE (Bluetooth low-energy, Bluetooth) is a complement to traditional Bluetooth BR/EDR technology. Although BLE and traditional Bluetooth are known as Bluetooth standards and share RF, ble is a completely different technology. ble does not have compatibility with traditional Bluetooth Br/edr . It is designed for small data rate, discrete transmission applications. Communication distances also change, traditional Bluetooth transmission di

At the end of the 19th century, the famous Russian dramatic director constanding Stanislavski created the "experiential performance" method, which shocked the entire dramatic industry. The focus of this method is to allow actors to control their own behaviors and then feel the real emotions on the stage. This kind of performance method is often referred to as "putting yourself in place" ("how can I behave if I am experiencing such emotional feelings ?"), It is widely used by many famous performi

The gas turbine flow meter collects the flow information by the flow sensor, and transmits the continuous analog signal to the microcontroller after the \ d converter discretization, the single-chip microcomputer meets the preset and expected control requirements under the control of the software system. It is an integral part of metering science and technology and is closely related to the national economy. Especially in the current energy crisis, th

Olya loves energy drinks. She loves them so much, She is the full of the empty cans from the energy drinks. Formally, her hostel can be represented as a field of nxm cells, each cell of the which is the empty or littered with cans. Olya drank a lot of energy drink, so now she can run K meters per second. Each second she chooses one of the four directions (up, dow

Leakage of PLC Ethernet modules of Mitsubishi Q Series added to the Energy Management System of Japan's North Ocean University For the safety analysis of the Mitsubishi Q series PLC, refer to the previous article. This is a real case of the control device running on the public network. It is also a case that can be confirmed based on the title.In theory, if the PLC does not set a password, it can implement remote management operations through programm

"High Energy" usage of linear-gradient, linear-gradientFirst, let's take a look at the basic usage of "linear-gradient: Note:Create an image with linear gradient Syntax: Valid value: The following values are used to indicate the gradient direction. You can use the angle or keyword to set them: To left: Set the gradient from right to left. Equivalent to: 270deg To right: Set the gradient from left to right. Equivalent to: 90deg To top: Set the grad

Yehuda Shinar is a winning research expert. after 18 years of scientific research and practical experience, after studying more than cases from different cultures and backgrounds, he found a very meaningful common law-the mode of thinking. Sina was inspired by the Demand Class theory (hierarchy of needs) of the famous psychologist Abraham Maslow, and further developed a set of universally applicable pyramid-based "winner model 」. His positive thinking rules have won praise from all walks of life

Microsoft has repeatedly declared that the upgrade of Windows 7 will save a lot of resources for enterprises. Today, green and environmental protection have become the focus of enterprises' attention, and energy conservation has to be considered. Recently, Mindteck, an embedded software development and consulting company, tested the power consumption of Windows 7 and XP in sleep, low usage, and high usage on multiple computers. From the test results,

Android Bluetooth Low Energy (Android Low-power Bluetooth) Android 4.3 (API Level 18) has introduced core functions of Bluetooth Low Energy (BLE, Low-power Bluetooth) and provided relevant APIs through which applications can scan devices and query services, characteristics (attribute feature) of a read/write device ). Compared with traditional Bluetooth, BLE can significantly reduce power consumption. This

Recently, when the ZigBee protocol was simulated in NS2. after the energy model was added, it was found that all nodes were green, and the changes in node color in the program were ineffective, you cannot add tags to a node. After carefully observing the source code, we found that the following two lines of the void mac802_15_4mac.cc line 919th: Recv (packet * P, Handler * h) function are in the p802_15_4mac.cc file: If (!
