Multiple Choice

Which technology is widely used to communicate IoT devices over short distances?

Short-range wireless connectivity is essential for many IoT setups because devices need to talk to each other and to gateways without wiring. Bluetooth, especially Bluetooth Low Energy, is designed for that: it provides low-power, short-distance links that are easy to pair and widely supported by phones, sensors, and hubs. This makes it ideal for connecting IoT devices in homes and small environments. In contrast, Ethernet, RS-232, and USB are wired options that require cables, which limits mobility and scalability for wireless IoT networking.
