Wifi Shield | Cannot reset wrong parameters

[d.payet]

Hi,

I would like to reset my wifi shield (wifly rn-171 on a Arduino Uno) because i’ve put wrong parameters (and i don’t know how ) and the shield connects automatically to the wrong SSID. I’ve tried all the example program to change the value, I’ve tried to send command (set join 0 etc) but none of theses did the trick.

I don’t understand how the button reset works, and I think I’ve tried a lot a things

Have you an idea ?

Thanks (and sorry for my english).

I’m back

I’ve tried a solution from this post : viewtopic.php?f=23&t=4432
Do you think it could be work with seeeduino wifi shield ?
I’m new to arduino and I am a little lost

I’ve put a wire on pin 8 and the IO9 (near the reset button ; btw how does this button work ? i did not success to make it working) with this (ugly) code :

[code]
void setup() {
pinMode(8, OUTPUT);
digitalWrite(8, HIGH);
delay(1000);
digitalWrite(8, !digitalRead(8));
delay(1000);
digitalWrite(8, !digitalRead(8));
delay(1000);
digitalWrite(8, !digitalRead(8));
delay(1000);
digitalWrite(8, !digitalRead(8));
delay(1000);
digitalWrite(8, !digitalRead(8));
delay(1000);
}

void loop() {

}[/code]

Hey , you dan download the specification , and you can see “19.1. 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.
