Bluetooth Smart is a low-energy wireless technology designed for short-range communication between devices. It allows gadgets like fitness trackers, smartwatches, and other IoT devices to connect and share data without draining their batteries quickly. This makes it ideal for applications that require constant connectivity but minimal power consumption. The technology operates on the same frequency as traditional Bluetooth, but it uses a different protocol to enhance energy efficiency. Bluetooth Smart is commonly used in health monitoring devices, smart home products, and various wearables, enabling seamless interaction and data exchange between devices while maintaining a long battery life.
