Bluetooth Low Energy (BLE) is a personal area network technology designed and sold by the Bluetooth Technology Alliance for emerging applications in healthcare, sports and fitness, Beacon, security, home entertainment and more. Compared to classic Bluetooth, Bluetooth low-power technology is designed to maintain the same communication range while significantly reducing power consumption and cost. Due to low power consumption, it is often used in a variety of common wearable devices and IoT devices. The button battery can last for months to years, is small, low cost, and is compatible with most existing mobile phones, tablets and computers. The Bluetooth Technology Alliance predicts that more than 90% of Bluetooth-enabled smartphones will support Bluetooth low-power technology by 2018.
Bluetooth low-energy technology is also beginning to support Mesh mesh networks. The new Mesh function can provide multi-to-many device transmission, and especially improve the communication performance of building a wide range of device networks, compared to the previous point-to-point (P2P) transmission of Bluetooth, That is, a communication network consisting of two single nodes. The Mesh network can treat each device as a single node in the network, so that all nodes can be connected to each other, expand the transmission range and scale, and enable each device to communicate with each other. It can be applied to building automation, sensor networks and other Internet of Things solutions that require multiple, even thousands, of devices to be transmitted in a stable and secure environment.
In addition, low-energy Bluetooth also supports Beacon micro-positioning technology. In short, Beacon is like a beacon that keeps on broadcasting signals. When the mobile phone enters the range of the lighthouse, Beacon will send a string of codes to After the mobile phone and mobile app detect the code, it will trigger a series of actions, such as downloading information from the cloud, or opening other apps or linking devices. Beacon has a more precise micro-positioning function than GPS, and can be used indoors to clearly identify any mobile phone that enters the signal transmission range. It can be used in digital marketing, electronic payment, indoor positioning and other applications.
