When module enables AP+STA function, Module’s STA interface can connect with router and connect
to TCP server in the network. At the same time, module’s AP interface is also active and permit
phone/PAD to connect through TCPB, then phone/PAD can control user device and and setting the
module parameters,
The advantage of AP+STA mode is:
 Users can easily setting and track user device through Phone/PAD and not change the
orginal network setting.
 Users can easily setting module’s parameters through WiFi when module works as STA
mode.
2.2. Work Mode : Transparent Transmission Mode
USR-WIFI232-G module support serial interface transparent transmission mode. The benefit of this
mode is achieves a plug and play serial data port, and reduces user complexity furthest. In this mode,
user should only configure the necessary parameters. After power on, module can automatically
connect to the default wireless network and server.
As in this mode, the module's serial port always work in the transparent transmission mode, so users
only need to think of it as a virtual serial cable, and send and receive data as using a simple serial. In
other words, the serial cable of users’ original serial devices is directly replaced with the module; user
devices can be easy for wireless data transmission without any changes.
The transparent transmission mode can fully compatible with user’s original software platform and
reduce the software development effort for integrate wireless data transmission.
The parameters which need to configure include:
 Wireless Network Parameters
 Wireless Network Name
（
