AP+STA Network Structure
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 original network setting.
Users can easily setting module’s parameters through WiFi when
module works as STA mode.

Work Mode : Transparent Transmission Mode
USR-WIFI232-T 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.
