Iot Wifi Modules Basic Function

Bidirectional transparent transmission via TTL serial port and Wifi.

Basic Function of Iot Wifi Modules

 

Iot Wifi Modules Transparent Transmission Mode

To achieve transparent transmission via the UART and the network.

To achieve data transmission via universal serial device and network equipment.

Transparent transmission mode is the default mode.

Iot Wifi Modules Transparent Transmission Mode

 

Iot Wifi Modules HTTPD Client Mode

Data transfer to the HTTP server directly, or to get data from the HTTP server side.

The serial data will be submitted to the web server in Http (GET / POST) mode directly.

It is the best choice to B / S architecture.

 

Iot Wifi Modules AT Command Mode

User can query/ set serial port and network parameters of WIFI module by AT commands.
