Hi all
i have arduino mega and #pn532
and i have code to open url in my android phone
the problem when i put phone on pn532
in serial monitor successfully url sent but no action in my phone
any help would be appreciated
#include <Wire.h>
#include <Adafruit_PN532.h>
// Create NFC instance (configure appropriate pins for your setup)
Adafruit_PN532 nfc(PN532_IRQ, PN532_RESET);
void setup(void) {
Serial.begin(115200);
Serial.println("NFC URL example");
nfc.begin();
uint32_t versiondata = nfc.getFirmwareVersion();
if (!versiondata) {
Serial.print("Didn't find PN53x board");
while (1);
}
// Display chip information
Serial.print("Found chip PN5"); Serial.println((versiondata >> 24) & 0xFF, HEX);
Serial.print("Firmware ver. "); Serial.print((versiondata >> 16) & 0xFF, DEC);
Serial.print('.'); Serial.println((versiondata >> & 0xFF, DEC);
// Set the NFC board in target mode (to respond to initiators)
nfc.SAMConfig();
Serial.println("Waiting for NFC reader ...");
}
void loop(void) {
uint8_t responseLength = 32;
bool success;
// Wait for a phone or device to be near
success = nfc.inListPassiveTarget();
if (success) {
Serial.println("Found something!");
// Prepare the NDEF message to open Google
uint8_t urlNDEF[] = {
0x03, // NDEF message start
0x0F, // Length of the NDEF message
0xD1, // NDEF Header (Short Record, URI Record Type)
0x01, // Type Length (1 byte)
0x0B, // Payload Length (11 bytes for "http://google.com")
0x55, // Type for URI record
0x01, // URI Identifier (0x01 for "http://")
'g', 'o', 'o', 'g', 'l', 'e', '.', 'c', 'o', 'm' // The URL "google.com"
};
uint8_t response[32];
// Send NDEF message
success = nfc.inDataExchange(urlNDEF, sizeof(urlNDEF), response, &responseLength);
if (success) {
Serial.println("Google URL sent successfully!");
} else {
Serial.println("Failed to send Google URL.");
}
} else {
Serial.println("Didn't find anything!");
}
delay(1000);
}
