Bluetooth 4.0

Bluetooth 4.0 is a wireless technology that allows devices like phones, fitness trackers, and headphones to communicate over short distances. It introduced a low energy mode, reducing power consumption significantly, which extends battery life for devices using it. This version is ideal for small gadgets that need to transfer data periodically, such as health monitors or smartwatches, without draining their batteries quickly. Bluetooth 4.0 maintains reliable connections while consuming less power, making it a popular choice for many modern connected devices, combining efficiency with convenience for seamless communication.
