Huge Beginners problems with Wifi Shield V 2.0

[hwv.wolf]

Hi everyone, I’m currently running the shield on an Arduino UNO. I started with the examples from the wiki and copied the following code:

#include <Arduino.h>

#include <SoftwareSerial.h>

#include “WiFly.h”



// set up a new serial port.

SoftwareSerial uart(2, 3); // create a serial connection to the WiFi shield TX and RX pins.

WiFly wifly(&uart); // create a WiFly library object using the serial connection to the WiFi shield we created above.



void setup()

{

uart.begin(9600); // start the serial connection to the shield

Serial.begin(9600); // start the Arduino serial monitor window connection

delay(3000); // wait 3 second to allow the serial/uart object to start

}



void loop()

{

while (wifly.available()) // if there is data available from the shield

{

Serial.write(wifly.read()); // display the data in the Serial monitor window.

}

while (Serial.available()) // if we typed a command

{

wifly.write(Serial.read()); // send the command to the WiFi shield.

}

}

I tried to enter the command mode by sending “$$$” in the serial monitor, but it doesnt work. No line ending, baud rate to 9600.

I read that the firmware version is displayed when you press the “Reset” button. When I try this the following text appears in the serial monitor:

54⸮⸮⸮⸮mw⸮⸮⸮2⸮E⸮⸮U⸮⸮{⸮⸮⸮⸮⸮⸮t4E⸮{tr⸮ 48Q⸮WU]⸮E⸮v⸮⸮P⸮⸮⸮

… just nonsense. If I repeat the process:

54⸮⸮⸮⸮mw⸮⸮⸮2⸮E⸮⸮U⸮⸮{⸮⸮⸮⸮⸮⸮t4E⸮{tr⸮ 48Q⸮WU]⸮E⸮v⸮⸮P⸮⸮⸮54⸮⸮⸮⸮ow⸮⸮⸮2⸮E⸮⸮U⸮⸮{⸮⸮⸮⸮⸮⸮t4E⸮{tr⸮ 48Q⸮QU]⸮E⸮t⸮⸮P⸮⸮⸮

The identical text repeats itself.

Please help me! I have already read some posts and do not know how to continue. I have already tried the shield on two different UNOs and re-installed the Arduino software. Is thies shield broken?



Kind regards from West-Germany

Hi,



Do you have a USB To UART module? You can use this to judge the problem.
