WiFi modules are two ways to build a transparent serial transmission of data

wifi module cost

This application, two wifi modules wireless networking WIFI point to point connection, as shown, so networking equipment for the user to build a transparent serial channel.
Set as follows:

(1) the left wifi module is set to AP mode, SSID and IP address of the default. Network protocol is set to TCP / Server mode, protocol port defaults to 8899.
(2) the right wifi module is set to STA mode, SSID is set to connect to the AP’s SSID. (USR-WIFI232-T), the default is DHCP, network protocol is set to TCP / Client mode

Protocol Port 8899, the target ip address as the address on the left of the module. That is 10.10.100.254.

When the right side of the module startup will find AP (SSID: USR-WIFI-T). Then the right side to the left side connection module TCP client module TCP server. All connections automatically. Then both sides of the UART can transparently transmit data.

wifi module interface

This application, the two wifi modules wifi wireless router wireless network connection point, as shown, a user equipment such as networking build a transparent serial passage.
Set as follows:

This application, two wifi modules via a wireless router for wireless point to point connection, as shown below, this network is to build a two user devices transparent serial channel.
The following figure is set as follows:

(1) on the left wifi module is set to STA mode, SSID is set to connect to a wireless router. IP address to 192.168.0.10. Set and a network router fixed IP address. Network protocol is set to TCP / Server mode, protocol port defaults to 8899.
(2) the right wifi module is set to STA mode, SSID is set to connect to a wireless router SSID. Network protocol is set to TCP / Client mode, protocol port 8899, ip address to the address on the left side of the module. That is 192.168.0.10.

When the two modules will start looking for AP (wireless router) and then connected to the left side to the right TCP client module TCP server. All connections automatically. Then both sides of the UART can transparently transmit data.
