Command Mode

Once the module is placed into Command mode, you are able to get or set a variety of configuration settings via specially formatted ASCII text messages on the Universal Asynchronous Receiver Transmitter (UART) interface.

​

Please see the "WiFly Command Reference Manual" for all details about specific commands and options.

Configuration Settings

Commands are broken into several configuration categories. They are identified by the top-level ASCII keywords shown in Figure 1:

​

Note:

  • Configuration settings are stored in the module's Flash memory.
  • After changing a configuration setting, the command "save" must be entered to save the changes to NVM.
  • Many changes require a reboot to take effect.

Command Structure

Most WiFly commands have the following structure:

"<Action Keyword> <Category Keyword> <Category Option> <Value>"

For example, the following command configures the SSID of the AP that the module is to associate with:

set wlan ssid IRF2111_1

Some commands are much simpler. For example, the following command returns the MAC address of the module:

get mac

The table in Figure 2 shows the common Action Keywords available:

Command Rules/Syntax

  • Commands are case-sensitive.
  • Spaces are not allowed. Substitute "$" for spaces. For example:
"MY NETWORK" must be entered as "MY$NETWORK"
  • Shorthand notation is available, per the following examples:
set uart baudrate 115200 // valid
set uart b 115200        // valid
set u b 115200           // valid
s uart baudrate 115200   // invalid
