3.2.2.1.2 Invoke Configuration Web Server in Software
If GPIO9 is not accessible using a pushbutton or jumper, an embedded microcontroller
can invoke the configuration web server mode in software using the ASCII command
run web_app. This command runs the configuration web server application and cre-
ates an AP network to which devices can join and configure the WiFly module from a
web browser.
3.2.2.2 STATUS LEDS IN CONFIGURATION WEB SERVER MODE
The status LEDs provide a visual indication of the WiFly module’s state while you use
the configuration web server feature. See Tabl e 3 -4.
3.2.3 Using the Web Server to Configure the Module
This section describes how to use the web server to configure the WiFly module with
the AP’s SSID and passphrase. The example uses the Internet Explorer web browser
running on a Windows 7 machine, however, the same concepts apply to any device
with a Wi-Fi interface (e.g., iPhone, Android smartphones, tablets, or PCs,) running a
web browser (e.g., Chrome, Firefox, or Safari).
To configure the module using a web browser, perform the following steps:
1. Associate your PC to the module’s AP network. Figure 3-3 shows a screen shot
displaying the network name.
