Bluetooth Low Energy (BLE), as a low-power wireless communication technology, has been widely used in the Internet of Things, smart devices, and health tracking.
The future of BLE technology is very bright. With the continuous expansion of the Internet of Things, BLE will continue to be applied in various fields. BLE 5.0 introduces higher transmission rate, longer transmission distance and stronger connection stability, providing more possibilities for applications.
In the future, BLE is expected to play a role in more vertical markets, such as industrial automation, smart cities, and smart transportation. At the same time, the continuous evolution of BLE technology will also bring more opportunities for developers to innovate. Low-power communication technology based on Bluetooth protocol, specially designed for low-power, short-distance communication. It enables efficient data transfer by quickly establishing, maintaining, and disconnecting connections. BLE uses an advertising and scanning mechanism, where advertising is used for devices to emit low-power signals for other devices to scan, and connections are established when needed for two-way communication.
One of the core concepts used by BLE is "Attributes", which define and organize data through the Generic Attribute Specification (GATT). Devices can publish services that contain different attributes, and attributes can be sensor data, control commands, etc. BLE data transfers are typically short-lived to reduce power consumption.
