In order to test WIFI module, we need connect module RS232 to PC and also WIFI to PC. In order to test the communication between serial and WIFI network, we need to connect the serial port to PC, and also connect WIFI networks to PC. Due to the special need both WIFI and serial, we use PC which add USB WIFI network Card such as the following picture.

3.5.3 UART Interface

UART interface is the serial data transmition interface mainly used for USR-WIFI232-A/B/C modules. User can add RS-232 chipset on user board and convert the signal to RS-232 voltage to communicate with outside equipment or sensors. USR-WIFI232-A/B/C modules UART interface include 4 general signals: TXD/RXD/RTS/CTS. The hardware reference design with RS-232 chipset as following:

Figure

Figure 21 Figure

Notes:

Notes: TXD pin is also hardware configuration pin internal module. So this pin MUST pull-down

during module power up. USR-WIFI232-A/B/C modules provide internal pull-down resister, user can ’ t add pull-up/pull-down resister on user board, which may cause module can ’ t work.

4.2.1 Transparent Mode

USR-WIFI232-A/B/C modules 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.

USR-WIFI232- A/B/C User Manual http://www.usriot.c om

The transparent transmission mode can fully compatible with user’s original software platform and reduce the software development effort for integrate wireless data transmission.

Notes:

Notes: Users also open the serial port hardware flow control (CTS/RTS) function, so that we can

make the bit error rate to a minimum.If the user doesn't need hardware flow control function of the serial port, only need to the corresponding pin foot (CTS/RTS) hung up.

4.2.2 Serial command mode

In this mode, the user can send the serial data to a different server address, this pattern can be use udp or TCP client sends data to the server. Customer MCU send packets according to the following format, parsing module is finished, only the n bytes of data sent to the destination address.When data is returned, not analytical data from serial port output directly.

In order to test the serial port to the WIFI network address conversion, we will module serial connected

with the computer, network and computer links to WIFI.

Due to the need to have both a WIFI and serial special requirements, only a minority of the notebook

computer can achieve, the user can use the desktop with a USB card, or use the notebook computer

with a USB to serial line way, the author uses the desktop and WIFI card form test, desktop with serial.

( Note: there USB transfer RS232 the line quality uneven, some good and some bad, in order not to

waste your valuable time, look for buying a used FT232 chip scheme suggested switching line, about

the price $ 10 )
