Page 11: One-Click Network Configuration Mode
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. -

When the module is configured in one-click mode, you need to set the module to one-click mode.You can use the serial configuration tool to set the module to one-click mode. Diagram 5 Set to one-click network mode 2.3. Serial to WiFi STA Serial device Diagram 6 Module as STA... -
Page 13: Serial To Wifi Ap
WiFi, and serial devices can transmit data through the B30 module and other WiFi devices. 2.5. Serial working state conversion After HLK-B30 is powered on, the default mode is transparent transmission mode. By pulling down the ES0 (PIN5) pin for more than 50ms to enter the at command mode, the module will regard the received data as an at command and send the at command to let the module enter the transparent transmission mode. -

2.6. Serial to Network Data Conversion 2.6.1. Module as TCP Server TCP Client TCP Client TCP Server TCP Server TCP Client Diagram 9 TCP Server In this mode, the module monitors the designated port and waits for the TCP Client to connect. After the connection, all TCP data are sent directly to the serial port, and the data at the serial port is sent to all TCP Clients. -
Page 15: Module As Udp Server
2.6.3. Module as UDP Server UDP Client UDP Server Diagram 11 UDP Server In this mode, the module opens the local designated port. Once receiving the data sent to this port, the module will send the data to the serial port and record the remote IP and port. The module will only record the remote information on the last connection, and the data sent by the serial port will be directly sent to the recorded remote IP and port. -
