Bluetooth Low Energy (BLE) is designed for low-power, short-range communication, making it ideal for IoT devices like wearables and smart home gadgets. BLE operates within the 2.4 GHz ISM band and consumes minimal energy, ensuring long battery life for connected devices. • Example: A fitness tracker uses BLE to sync data with a smartphone. The protocol ensures reliable communication without draining the device's battery. ________________________________________ Why Other Options Are Incorrect: 1. HTTP: HTTP is heavy and unsuitable for low-power IoT communication. 2. FTP: FTP is used for file transfers, not for real-time IoT communication. 3.
