Wi-Fi is a technology that allowselectronic devices to connect to a wireless local area network (WLAN),typically using a 2.4G UHF or 5G SHF ISM RF band. Connecting to a wireless LANis usually password protected; but it can also be open, allowing any devicewithin the WLAN range to be connected. Wi-Fi is a brand of wireless networkcommunication technology and is owned by the Wi-Fi Alliance. The goal is toimprove interoperability between wireless network products based on the IEEE802.11 standard. Some people use the LAN that uses the IEEE 802.11 family ofprotocols as wireless fidelity. Even they consider Wi-Fi is equated withwireless internet (Wi-Fi is an important part of WLAN). Smart home is theembodiment of materialization under the influence of the Internet. Smart Homeconnects various devices in the home (such as audio and video equipment,lighting systems, curtain control, air conditioning control, security systems,digital cinema systems, audio and video servers, video cabinet systems, networkappliances, etc.) through IoT technology. Home appliances control, lightingcontrol, telephone remote control, indoor and outdoor remote control,anti-theft alarm, environmental monitoring, HVAC control, infrared forwardingand programmable timing control and other functions and means. Compared withordinary homes, smart homes not only features traditional living functions, butalso have construction, network communication, information appliances,equipment automation, which provides a full range of information interactionfunctions, and saves money for various energy costs.
The annual shipment of hundreds ofmillions of smart phones and tablets worldwide has laid a good foundation forthe control platform of smart homes. Due to the huge amount of smart phones andtablets, the popularity of home WiFi networks and the reduced cost of WiFimodules, smart home devices, such as smart lights, refrigerators, airpurifiers, etc., generally uses WiFi as a means of data interaction. However,due to the cost and aesthetics of smart homes, it is impossible to have toomany interactive devices on the outside. It is likely to be a limited number ofbuttons or even no buttons. When the smart device is connected for the firsttime or when the network is to be changed, how to make it simpler,operation isa matter of design that requires special consideration, and smartconfigtechnology is a good solution. Smartconfig technology allows a smart homedevice to be connected to the same LAN as the mobile phone with a simpleoperation on the mobile phone, without having to set too many function buttonsoutside the device, which is both beautiful and simple to use. The followingpicture is the introduction interface of the Xiaomi socket. Here, the WiFiquick connection technology is used, and the configuration is simple.
The E103-W01 has a Smart Configfunction that allows users to quickly connect to the network using the mobileAPP configuration module. When the module is in STATION mode, send the command“AT+CWSTARTSMART” to enter the Smart Config mode, in which the module waits forthe mobile terminal to configure. The user only needs to start EspTouchAPP onthe mobile phone (provided by Lexin official website to provide download ormodule attachment), the user only needs to input the router password of thecurrent mobile phone on the APP, so that the module can be connected to thesame router as the mobile phone.
In the design equipment, E103-W01is selected as the communication module, and a button with smartconfig functioncan be set outside the smart home device to realize the configuration, which issimple, beautiful and convenient.
