You could also have specified the roving1 access point by using the command
join # 1
If the access point is security enabled you will need to set the pass phrase prior to issuing the
join
command.
The RN-131G module will attempt to inquire and determine the security protocol of the access point so you
do not have to set the authentication mode. To set the pass phrase for WPA use the command
set wlan
phrase <string>
. For WEP set the key using the
set wlan key <num>
command.
Once you have successfully associated to the network the access point SSID is stored. This along with the
pass phrase can be saved to the config file so the module can associate with the network each time it is
booted up.

Making Connections
To make a connection into the module simply open a IP socket and connect to the IP address of the module.
Telnet is a simple way to test this connection. From in Telnet type open <addr> <port>. In the example
above the telnet command you look like
open 10.20.20.62 2000
. Once open you can type characters into
the UART window and see them on the Telnet window or visa versa.
To make a connection from the module you will need IP address and port number of your server
application. A simple program to test this functionality is a COM port redirector. This software opens an
IP port and transfers all data it receives to a specified COM port on your machine. A free com port
redirector program is available from Pira at http://www.pira.cz/eng/piracom.htm
After installing and starting this program, note the IP address of the machine it is running on. This can be
found by running ipconfig in the Microsoft command window.
With the WiFly-GSX module in command mode, type
open <addr> <port>
. The server will report the
connection is open and you can type characters into the UART window and see them on the server window
or vice versa.

Setting up Automatic Connections
Often, it is desired on power up (or wakeup) to automatically connect out to a remote server, send data, and
then disconnect. This can be configured to happen automatically.
