The WiFi to Serial module is an embedded WiFI / Ethernet to Serial module that would allow you to connect your existing serial microcontroller project to the Internet. The module has a web configuration page, that will allow you to change various module settings like UART baud rate, WIFI AP SSID , IP addresses DHCP etc. The module is based on the OpenWRT firmware and it uses a modified version of the Serial2Net application that is designed to run on OpenWRT Distribution.
How It Works?
The WiFi to Serial module is practically a WiFi 802.11n wifi router that broadcasts its own SSID. The clients can connect to the WiFi to Serial module’s via WiFi. Once a connection is established the client gets an IP address from the WiFi to Serial module. The WiFi to Serial module main task is to redirect its Serial port input/output to a specific TCP/IP port . This means that if the module IP address is 192.168.16.254 you can configure the Serial2Net app to listen at 192.168.16.254:8080 . If you connect via socket to this port you will be able to send / receive commands to the WiFi to Serial module serial port and respectively to the microcontroller connected to that port.
