5. Exchanging data between the Wi-Fi module and Laptop (A)

a. Open a server TCP socket in the module

a+rsi_ltcp=5001

b. Open a TCP socket in the Laptop (A) by typing the below

command in the Windows command line interface. Make sure

that any firewalls, that might prevent opening of sockets, are

disabled.

TCP.exe c 2001 192.168.50.10 5001

The application is found in the path

RS.CN.xx.GENR.UT.x.x.x\Software\Applications\Windows\.

c. The command line window will display three options: 1 (Send),

2 (Receive) and 3 (Exit). Type 1 to send data to the Wi-Fi

module. On being prompted “Enter the string to be

Transmitted”, type any string from the Keyboard. On pressing

“Enter” key, the data is sent from the Laptop (A) to the module

and the terminal displays it with the AT+RSI_READ message.

d. To send data from the Wi-Fi module, first type Option 2 in

Laptop (A) and then type the below command in the module

at+rsi_snd=1,0,0,0,Data sent from Module

The first parameter in the command is the socket_handle. It is 1

in this case. It is returned as the response of the command

at+rsi_ltcp and can be observed in Serial Port Monitor software.

The data sent will be displayed in the Laptop (A).

NOTE: All bytes sent by the module to the Host PC may not be readable because

HyperTerminal converts some bytes into unreadable ASCII characters. There are

several applications similar to HyperTerminal and available online that can be used

to issue AT commands and also view the actual bytes returned by the module to

the Host. Such applications may be used instead of HyperTerminal to operate the

module using a PC.
