The text explores the distinctions between Bluetooth Classic and Bluetooth Low Energy (BLE), emphasizing their different applications and efficiencies. Bluetooth Classic is traditionally used for devices requiring high data rates like audio streaming, while BLE is designed for low-power, intermittent transmission suitable for IoT devices. The text outlines how BLE's lower energy consumption and longer connection range make it preferable for certain use cases, such as wearables and smart home devices, where battery life and consistent connections are crucial. It highlights the adoption of BLE by Ditto, a company that leverages this technology for efficient data synchronization across devices. BLE's advantages include supporting multiple connections simultaneously and providing a more energy-efficient option for maintaining long-term connectivity. This shift towards BLE is driven by the growing need for energy-efficient solutions in the expanding landscape of IoT devices.
