3.2.2 Using the Configuration Web Server
Configuring the embedded WiFly module to associate with an AP in infrastructure
mode involves the following process:
1. Invoke the module’s configuration web server.
2. Connect your client device (PC, smartphone, tablet, etc.) to the module’s soft AP
network.
3. Access the module’s configuration web page from your client device’s web
browser.
4. Save the settings (SSID and passphrase) in your web browser and exit.
3.2.2.1 INVOKE THE CONFIGURATION WEB SERVER
There are two methods for enabling the web server: hardware and software. When you
invoke the configuration web server, it creates a soft AP network with the settings
shown in Table 3-3.
3.2.2.1.1 Invoke Configuration Web Server in Hardware
You can invoke the web server in hardware using GPIO9. To use GPIO9, specify that
the web application should launch using command set sys launch_string web_app
(default configuration).
With the launch string set, drive GPIO9 high any time after power up to invoke the web
server. The module creates a soft AP mode network with the parameters described in
Tabl e 3-3.
TABLE 3-3: SOFT AP NETWORK SETTINGS
Setting Soft AP Mode Default
SSID WiFly-GSX-XX for RN131G/C
WiFly-EXZ-XX for RN171
where XX is the last byte of the module’s MAC address
Channel 1
DHCP server Enabled
IP address 1.2.3.4
Netmask 255.255.255.0
Gateway 1.2.3.4
Note: The soft AP network’s SSID uses the module’s device ID parameter. If you
change the device ID parameter using the set opt device_id <string> com-
mand, the module uses this new device ID as the soft AP network’s SSID.
The device ID parameter is not set to a default if you perform a factory reset.
Note 1: Do not drive GPIO9 high upon power up. Doing so invokes soft AP mode
and does not launch the web server.
2: If you are using an evaluation kit, GPIO9 is accessible using a jumper or
pushbutton.
