Device Pairing

Last Updated on : 2024-04-03 10:32:27download

Pairing is the process of connecting a smart device to a router for internet access. The following pairing modes are supported:

  • Wi-Fi Easy Connect (EZ) mode
  • Access point (AP) mode
  • Wired device pairing
  • Sub-device pairing
  • Bluetooth device pairing. For more information, see Bluetooth Technology Stack.


Term Explanation
Wi-Fi device A smart device that uses a Wi-Fi module to connect to a router and interact with apps and the cloud.
Wi-Fi Easy Connect Also known as the EZ mode. How it works:
  1. The app encapsulates the pairing data into the specified section of an IEEE 802.11 packet and sends the packet to the network.
  2. The Wi-Fi module of a smart device runs in promiscuous mode and listens for and captures all packets over the network.
  3. The Wi-Fi module parses the captured packet to extract pairing information.
AP pairing Also known as the AP mode. A mobile phone acts as a station (STA) and connects to the AP of a smart device. Then, both devices establish a socket connection to exchange data through a designated port.
Wired device A device that connects to a router through an Ethernet cable, for example, a wired Zigbee gateway and a wired camera.
Sub-device A device that interacts with the app and the cloud through a gateway, for example, a Zigbee sub-device.
Zigbee Zigbee is a short-range, simple, low-power, low-data-rate, cost-efficient, and two-way wireless communication technology.
It applies to short-range, low-power, and low-rate data transfer between various electronic devices, periodic data transfer, intermittent data transfer, and data transfer at a longer interval.
Zigbee gateway The device that integrates the Zigbee coordinator and Wi-Fi features. It is used for Zigbee networking and data storage.
Zigbee sub-device A router or an end device on a Zigbee network. Each Zigbee sub-device forwards data, or responds to control commands.
