ACTION COMMANDS
The action commands allow you to enter and exit command mode, join networks, etc. Except where noted, these
commands do not have any parameters.
$$$
You use this command to enter command mode. You must type $$$ together quickly with no additional characters
before or after. You must not type a carriage return (<cr>) after the $$$ to enter command mode. The module replies
with CMD to indicate it is in command mode. There is a 250-ms buffer before and after the $$$ escape sequence. If
characters are sent before or after the escape sequence within this 250-ms interval, the WiFly module treats them as
data and passes them over the TCP or UDP socket, and the module will not enter command mode.
If you want to use different characters to enter command mode (not $$$), you can set the character to use with the
set comm $ <char> command.
Example: $$$ // Enter command mode
close
This command disconnects a TCP connection.
Example: close // Close the TCP connection
exit
This command exits command mode. After leaving command mode, the module responds with EXIT.
Example: exit // Leave command mode
factory RESET
This command loads the factory defaults into the module’s RAM and writes the settings to the standard configuration
file. You must type the word RESET in capital letters. After you type this command, you must reboot the module for
the settings to take effect.
Example: factory RESET // Reset the configuration settings to the factory defaults
