Bluetooth is a short-range wireless standard designed for low-cost, low-power wireless connections. Bluetooth is useful for connecting smart home appliances, smartphones and electronic devices such as keyboards, computer mice, printers, wireless headsets and more. Both Zigbee and Bluetooth wireless protocols work well for local communications in Internet of Things applications. However, each is useful in different IoT use cases. Best of all, they can work together to create extremely flexible applications. In fact, both protocols can work side by side. This capability is available in our Digi XBee 3 Zigbee modules — Bluetooth for short range configuration and troubleshooting, and Zigbee for the mesh networking protocol.
