18.1. Restoring Default configuration settings:
From command interface use the factory RESET command to restore the defaults. This command
automatically loads default settings, and executes a “save” command. You then need to issue the reboot
command so that the module reboots with the default configurations.
From hardware, setting PIO9 high on power up arms the factory reset functional and toggling PIO9 five (5)
times there after causes the configuration setting to restored to the factory reset.
PIO9 is sampled at about 1 Hz, so if using a CPU to generate the signal, make sure that PIO9 transitions (H
to L or L to H) are at least 1 second long.
User file option
As of version 2.10 you can now specify a USER configuration as the factory reset settings. Prior to this
release only the hardcoded factory defaults would be restored. If there is a config file named "user", it is
read in as the factory defaults instead of using the factory hardcoded defaults. If no "user" config file is
present, the hardcoded factory defaults are used.
The "user" config file is created using the "save user" command, which saves the current configuration
settings into the “user” file.
Even if there is a “user” config file arming and toggling PIO9 7 times will override the “user” settings and
restore the WiFly module to the factory hardcoded defaults. This is a bypass mechanism in case a bad
configuration is saved into the “user” file.
Note: The module should be rebooted, or reset with reset line for the new settings to take effect.
