Hi ,

My problem is my arduino and eifi wifi shield(wizfi210) not communicate each other.I try own page code ([elecfreaks.com/wiki/index.ph … eld_-_EiFi](http://www.elecfreaks.com/wiki/index.php?title=Wifi_Shield_-_EiFi)) and not working.

it continues …

I have tried :

wifi shield pin DOUT-D2 , DIN-D3. arduino code tx-pin 2 rx-pin 3 , use software serial lib.

[code]#include <SoftwareSerial.h>

#define rxPin 2
#define txPin 3

SoftwareSerial mySerial(rxPin, txPin);

void setup()
{
pinMode(rxPin, INPUT);
pinMode(txPin, OUTPUT);
mySerial.begin(9600); // setting baud to 9600
Serial.begin(9600);
}

void loop()
{

mySerial.write(“AT\r\n”);

char rcv;

if(mySerial.available())
{
rcv = mySerial.read();
}

Serial.print(rcv);

delay(1000);
}[/code]

I use this code result " ÿ " char . What does it mean ?

Where is the problem ?

Hi

I am sorry for late reply.
I think it is problem in order to baud rate setting of WizFi210.

Frankly speaking, This shield and library is not made by Wiznet.

So I recommend you to ask to ELEC Freaks. Maybe there give more correct answer to you due to make library and shield by them.

Thank you.

Did you solve this problem? I have a same situation… ![:unamused:](https://emoji.discourse-cdn.com/twitter/unamused.png?v=12)
I could’nt find any information .
There is no community to elecfreak.
I think wifi module is not connected for some reasons.
