2.2. One-click network configuration mode
For the IOT WiFi module, based on cost and performance considerations, there is no touch
screen interactive interface like a mobile phone. The user can see the ap list on the mobile phone and
click on the password to connect to the network. What should I do? One-click configuration is that
the WiFi module is in promiscuous mode (can capture all 802.11 frames in the air), the APP sends
the SSID and password to the WiFi module through UDP broadcast or multicast with certain coding
rules, the module parses them out, and then connects to the router. Install the Android app
HLK-TCPdemo, then select the configuration network, select the airkiss mode, enter the password,
click to start the configuration and start the configuration. When the network connection is
successful, the module will change from dual flash to fast flash, indicating that the network is
successful.
