Introduction to android Bluetooth Low-energy (LBE) Technology Bluetooth Low-energy (BLE) technology is a low-cost, short-distance, and interoperable Robust Wireless Technology that works in a licensed 2.4 GHz ism rf band. It was designed as an ultra-low power (ULP) wireless technology from the very beginning. It uses many smart means to minimize power consumption. Bluetooth Low energy technology uses a variable connection interval, which can be set to

manufacturers of high-speed transformation, the mobile app to seize the market, the opportunity is still there.How to develop mobile app to control home smart home?As an employee with many years of experience in the development of smart home apps, the following is a word.App development first difficulty data communication. This is a way of requiring a command to be sent to a repeater (Controller), which is sent by a repeater to control the smart device. There is also a direct control of the s

Halow makes up for the short board of the existing WiFi technology with high power consumption and short distance (which is also the main reason for its restriction in home control), making WiFi a wireless standard that can also transmit Low Power micro data. However, the low power consumption performance of Zigbee, BLE, Enocean and other communication protocols is also significant. To what extent can Halow's low power consumption be achie

will always try to fill the black ball in the missing position, and then restore the original ball to the position of 2. When n is an even number, we know that the relative positions between the balls are fixed, that is, the parity cannot be changed. In this case, when and only when the position of the ball meets the requirements, in order to achieve the goal.

dimming interfaces can be connected to Zigbee dimming devices. Lighting customers do not need to design Wireless RF devices. They only need to connect the corresponding interfaces to the dimming devices, in this way, you do not need to change the design of your existing products, greatly reducing your product development cycle and costs. 3) gateway; 4) software, as part of the network layer. As a part of the Smart Home System, smart lighting is crucial to the interconnection and Stability of mu
