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

Android4.3 (API level 18) introduces a built-in platform to support the central role of BLE, while providing APIs and app applications for discovering devices, querying services, and reading/writing characteristics. Unlike traditional Bluetooth (Classicbluetooth), Bluetooth low power (BLE) is designed to provide more significant low power consumption. This allows Android applications to communicate with low

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 transmissio

To do embedded development, UART is almost essential, debugging serial port, GPS, GPRS, Bluetooth and many other modules are used UART interface. Nowadays the hot IoT also has the UART figure, the serial port ble, WIFI, Zigbee, Lora and so on module, a bunch of piles. The NUC972 mentioned in the previous article even built up 11 UART, it can be understood. Although has been based on the serial port to do a lot of tool software, such as s3c2410 of the

I. Overview 1. BLE Bluetooth protocol stack structure Figure 6 BLE Bluetooth protocol stack structure There are two parts: controller and host. For Bluetooth prior to 4.0, the two parts are separated. All profiles (or scripts used to define the role of a device or component) and applications are built on the GAP or GATT. The following describes the underlying components of the structure chart. · PHY layer

Although command execution requires the necessary code, the command executor provides the necessary support during command execution. For example, draw a Windows form with a text box. Some text must be added to the text box when a command is executed. But the command is an independent class, and it does not reference the text box in the f

Ibeacon is a hot topic recently. This technology enables indoor positioning, allowing your mobile phone to know if it is within the beacon range. Using this technology can produce many applications, such as helping you find your car in the parking lot, or providing coupons or location-related services in retail stores. There are many applications that we cannot imagine now. There are many explanations about what ibeacon is and how we can use it. However, from a technical point of view, how do th

The HART Smart Transmitter is an important application of the HART protocol in smart devices. This article will take this as an example to explain the principles of this part. First, we need to understand the concept of the Smart Transmitter and the basic knowledge of the HART protocol tank. The field bus technology is one of the hot spots in the Current Automatic Detection Technology. From the formation of

Particle SystemIt is a two-dimensional image rendered in 3D controls, mainly used for smoke, fire, water drops, fallen leaves and other effects. A particle system consists of three independent parts: an example transmitter, a particle animation, and a particle Renderer. Some particle effects are included in unity.

ObjectivePeople who know about Bluetooth know that in classic Bluetooth, staying connected (Connection) is a fairly resource-intensive (power and bandwidth) process. In particular, when there is no data transfer, the resources consumed are completely wasted. Thus, for many Bluetooth devices (especially power-sensitive devices), it is hoped that it will be able to disconnect during countless passes. However, because of th

Feedback can be directly used for adaptive coding []. The experiment of IP multicast also shows that it is the key to get feedback information from the receiver to diagnose transmission faults. Sending receiving feedback to all members enables "observers" to assess whether the problem is local or global. Similar to the IP multicast distribution mech

objects. The author simplified the DX framework and reduced unnecessary items. Because it is a read code, it is natural to speculate on the code based on the name. If we cannot speculate on the random name, we can speculate on it based on the context or set the breakpoint and dynamic variable data value, it can be seen that a good naming method is easier to read, but a bad naming method is not an excuse for us to read. The key is what it implements. ///------------------------------------------

1. DSA-Interface Specification The DSA bus is an asynchronous and bidirectional communication bus designed internally for communication between a group of two microprocessors. It has three bidirectional lines: ● Data-start synchronization and Data Transmission ● STB-data Election (data is valid when STB Is low) ● Ack-start synchronization, data transmission, confirmation and communication response 2. Communication instructions Each data communication includes three phases: ● Star
