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.
