Hi, I'm new to arduino, first of all, excuse my english...
I have an Arduino UNO connected with an Ethernet Shield + rc522 RFID reader, I would like to get the Tag ID card and send it using GET mounted to a local server with XAMPP.
- the apache server is online (checked)
- WS receives the parameter is at http: //localhost/dir1/obtienevalor.php (checked)
- rc522 reader reads TagId I connected on ethernet shield works! (checked)
- ethernet shield works alone (checked)
I need to read the tag id and send using GET to obtienevalor.php to process,the problem is that the connection to the server fails, and I can not send TagId.
apparently ethernet shield not working with Reader rc522, rc522 reader settings this within my code:
/**
* Read a card using a mfrc522 reader on your SPI interface
* Pin layout should be as follows (on Arduino Uno):
* MOSI: Pin 11 / ICSP-4
* MISO: Pin 12 / ICSP-1
* SCK: Pin 13 / ISCP-3
* SS: Pin 7
* RST: Pin 9

#include <SPI.h>

// Mac unica de cada EthernetShield (deben cambiarla)

// Envia el requerimiento al servidor via GET

client.println();
}
else {
// Si la conexion fallo se desconecta
Serial.println("Error al conectarse al servidor");
Serial.println("Desconectando...");
client.stop();
}
} else {
/* If we have the same ID, just write a dot. */
Serial.print(".");
}
}
}
rfid.halt();
}
someone could give me a hint? attached photo of monitor serial and arduino settings
Thanks in advance
still i have no solution for my project..
