Device Pairing

Last Updated on : 2022-02-17 07:02:57

Device Pairing SDK allows smart devices to be paired through routers. The following pairing modes are supported:

Wi-Fi Easy Connect (EZ) mode
Wi-Fi (access point) AP mode
Smart camera pairing in QR code mode
Wired device pairing
Sub-device pairing
Device pairing in QR code mode
Pegasus pairing mode
NB-IoT device pairing
For more information about Bluetooth device pairing, see Bluetooth Devices.

Term	Definition
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 EZ mode	The app encapsulates the pairing data into the specified section of an IEEE 802.11 packet and sends the packet to the network. The Wi-Fi module of a smart device runs in promiscuous mode and listens for and captures all packets over the network. The Wi-Fi mode parses the packets that carry the pairing data from the app into the data format specified by the protocol.
AP pairing	Also known as the hotspot mode. A mobile phone acts as a station (STA) and connects to the hotspot of a smart device. Then, both devices are paired to establish a socket connection between them and exchange data through the specified ports.
Smart camera pairing in QR code mode	A smart camera scans the QR code on the app to get the pairing data.
Wired device	A device that connects to a router over a wired network. For example, a wired device can be a Zigbee wired gateway or a wired camera.
Sub-device	A device that interacts with apps and the cloud through a gateway. For example, a Zigbee sub-device is such a 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 coordinator with Wi-Fi features on a Zigbee network. The gateway is responsible to formulate the Zigbee network and store data.
Zigbee sub-device	A router or a terminal on a Zigbee network. Each Zigbee sub-device is responsible to forward data or respond to terminal control commands.
