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 (!

What is the use of the MVC development model for?? MVC is a design pattern that makes it mandatory to separate the input, processing, and output of an application. Using an MVC application is divided into three core parts: model, view, controller. Each of them handles their own tasks. Is it necessary for us to strictly distinguish between MVC's three-layer mode mode? Cross-border use of M and C is more conducive to rapid development. In the framework I use, M and C can be used across borders, no
