CONFIGURATION
When using the standard WiFly firmware, the module operates in two modes: data mode (default) and command
mode. While in data mode, the module is essentially a data pipe. When the module receives data over Wi-Fi, it strips
the TCP/IP headers and trailers and passes the user data to the UART. When data is written to the UART, the
module constructs the TCP/IP packet and sends it out over Wi-Fi. Thus, the entire process of sending/receiving data
to the host is transparent to the end microprocessor. See Figure 2.
Figure 2. Data & Command Modes
By default, the module is in data mode. Sending the escape sequence $$$ causes the module to enter command
mode. Once in command mode, you can configure the WiFly device using simple ASCII commands. To exit
command mode and return to data mode, type exit <cr>.
Basic configuration only requires the wireless network access point’s name (SSID) and authentication password. The
WiFly module can only associate with one network at a time. Roving Networks recommends that you begin your
evaluation by configuring the WiFly module using an open access point to simplify the setup.
There are two ways to configure the WiFly module:
You need a terminal emulator to complete the setup.
Configuration Using the RS-232 Serial Interface
The USB-to-serial cable allows your computer to communicate with the WiFly module on your evaluation board. The
following instructions describe how to use a terminal emulator to go into configuration mode, send commands to find
networks, associate with an access point, and save your configuration.
