- Setup WiFi and PN532: Connect to the WiFi network and initialize the PN532 NFC reader.
- Reading NFC Tags: The readNFC function reads NFC tags, decodes the URI and text fields, and sends them to a specified HTTP endpoint.
- HTTP Server: The ESP8266 hosts an HTTP server with a /writeNDEF endpoint to receive JSON payloads to write to NFC tags.
- Writing to NFC Tags: The writeNDEFToTag function writes the received URI and description to a new NFC tag.
- Ensure you replace YOUR_SSID, YOUR_PASSWORD, and http://yourserver.com/endpoint with your actual WiFi credentials and server URL.
- The code uses NdefRecord for creating URI and text records. Adjust as needed based on your NFC library's API.
