Bluetooth Low Energy (BLE) and ZigBee for Wearables
Allan Kipkirui Koech · Wearable Technology · 2025
Bluetooth Low Energy (BLE) and ZigBee are two wireless technologies used in wearable devices and smart gadgets. BLE is a short-range, low-power system that allows devices like fitness trackers to send data quickly to a main device such as a smartphone. It uses simple rules and unique IDs to manage data sharing. ZigBee is designed for building small, low-cost networks, often found in smart homes, where devices connect in patterns like star or mesh layouts. Together, these technologies help devices communicate efficiently, securely, and in real time.
