Re: WiFi AdHoc mode change

Hi Karl,

To change the configuration of the WiFi module you can only do that over the WiFi link as you have determined.

YOU MUST BE COMFORTABLE WITH MAKING THESE TYPES OF CONFIGURATION CHANGES PRIOR TO DOING THIS!

That is why we put the warning in the application note.

To assuage your fears about getting locked out of the WiFi module if you misconfigure something according to the directions in the Application Note and Microchip RN-131 manual: 
http://hosted.comm100.com/KnowledgeBase/PMC-Eight-Application-Note--AN002-How-To-Configure-and-Switch-Between-the-WiFi-and-Serial-Connections_A5000038.aspx?id=5000038&siteid=56501

The Microchip RN-131 manual Provides instructions on page 25 on how to do a SOFTWARE or HARDWARE factory reset using the GPIO9 pin which available on the WiFi daughter board along with the Power and GND. You can use an alligator jumper to perform this factory reset if you get stuck.

3.1.3 Restoring Default Configuration Settings
3.1.3.1 RESTORING THROUGH SOFTWARE AND HARDWARE
The default factory configuration settings can be restored in software and hardware.

• Software – In Command mode, use the factory RESET command to restore the
default settings. This command automatically loads the default settings and executes
a save command. Next, send the reboot command so that the RN module
reboots with the default configuration.

• Hardware – Set the GPIO9 pin high on power-up to enable the factory reset function.
Then, toggle GPIO9 five times, which restores the configuration to the factory
reset. The GPIO9 pin is sampled at approximately 1 Hz; therefore, if a CPU is
used to generate the signal, ensure that GPIO9 transitions (high-to-low or
low-to-high) for a period of at least one second.
