Capabilities & limitations

The PN532 is a hosted NFC controller, not a low-level RF lab instrument. This project exposes PN532 features honestly:

  • ISO14443-B: reader support exists with chip-level caveats (anticollision / stack-dependent behavior). No promises of full mobile/PICC coverage.
  • Card emulation / TG modes: PN532 firmware supports target commands; real-world mimicry depends on timing, UID size, and reader expectations — expose experimentally, not as “propable MIFARE magic.”
  • Key recovery: on-device “brute force” at Proxmark scale is infeasible. The UI provides dictionary / manual key workflows.
  • Signal / RF metrics: diagnostics use PN532 status / timings / retries, not calibrated dBm.
  • OTA via UI: POST /api/ota is a stub (501) — ship OTA with esp_https_ota + signed images when you need production updates.
