How to use Wifi Shield(Fi250) on Arduino UNO

1. Reset the module as factory default. Press the function three times at fast speed;2. Upload sketch Blink to Wifi Shield(Fi250);3. Connect WIFI_TX to D1 and WIFI_RX to D0 with jumper hats on shield;4. Open Serial Port Tool, then send AT+USET=baud rate,N,8,1,N(Baud rate should be lower than 115200).For example, AT+USET=38400,N,8,1,N, and you will see OK returned.

5. Change the jumper hats to connect WIFI_TX with D6 and WIFI_RX with D7.6. Upload the code below.7. Open serial monitor, and you will see it successfully joins wifi with the Red LED lit.

#include #include #include "WizFi250.h"

#define SSID "Your-SSID"#define KEY "Password"#define AUTH "WPA2"

#define spi_CS 8

SoftwareSerial uart(6, 7);WizFi250 wizfi250(&uart);

void setup() {Serial.begin(38400); //change to the right baud rateTOP

uart.begin(38400); //change to the right baud rate

pinMode(spi_CS,OUTPUT);digitalWrite(spi_CS,HIGH);Serial.println("--------- WIZFI250 TEST --------");// wait for initilization of Wizfi250// wizfi250.reset(); delay(1000); Serial.println("Join " SSID ); delay(10); if (wizfi250.join(SSID, KEY, AUTH)) { Serial.println("Successfully join " SSID); } else { Serial.println("Failed join " SSID); } wizfi250.clear(); Serial.println("*************send command to get Wizfi250 status******************"); wizfi250.sendCommand("AT+WSTAT\r"); //delay(10); char c; while (wizfi250.receive((uint8_t *)&c, 1, 100) > 0) { Serial.print((char)c); }

}void loop() { while (wizfi250.available()) { Serial.write(wizfi250.read()); } while (Serial.available()) { wizfi250.write(Serial.read());}}
