#49003 Wifi 3click board: http://download.mikroe.com/documents/ad ... l-v100.pdf

I've got a ESP8266mod, which comes in a wifi click 3 board. After connecting it to m arduino following this guide:


http://iot-playground.com/blog/2-uncate ... connection

(Only the arduino tx to the wifi rx, because i receive data and transmit data, so i think i dont need the other two connections(reset and wifi tx to arduino rx))

The problem is this; i restart my wifi board, and it says ready, but when a send an AT command it answers strange things, I've set it in "Both NL & CR" and Baud to 9600, and my code is:



#include <SoftwareSerial.h>

SoftwareSerial esp8266(2,3); // make RX Arduino line is pin 2, make TX Arduino line is pin 3.
// This means that you need to connect the TX line from the esp to the Arduino's pin 2
// and the RX line from the esp to the Arduino's pin 3
void setup()
{
Serial.begin(9600);
esp8266.begin(9600); // your esp's baud rate might be different
}

void loop()
{
if(esp8266.available()) // check if the esp is sending a message
{
while(esp8266.available())
{
// The esp has data so display its output to the serial window
char c = esp8266.read(); // read the next character.
Serial.write(c);
}
}



if(Serial.available())
{
// the following delay is required because otherwise the arduino will read the first letter of the command but not the rest
// In other words without the delay if you use AT+RST, for example, the Arduino will read the letter A send it, then read the rest and send it
// but we want to send everything at the same time.
delay(1000);

String command="";

while(Serial.available()) // read the command character by character
{
// read one character
command+=(char)Serial.read();
}
esp8266.println(command); // send the read character to the esp8266
}
}



Any idea of why this happens or how to fix it?
