Halaman ini menjelaskan cara mengontrol NFC di perangkat Cuttlefish menggunakan
fitur NFC Cuttlefish. NFC didukung di perangkat Cuttlefish yang menjalankan
Android 15 atau yang lebih baru.
Menggunakan Casimir
Fitur NFC Cuttlefish menggunakan Casimir, alat simulasi perangkat NFC eksternal,
yang mendukung injeksi byte APDU untuk emulasi kartu host. Casimir
diimplementasikan di
/platform/system/nfc/tools/casimir/.
Saat meluncurkan Cuttlefish, Casimir juga diluncurkan secara default. Untuk
mengontrol Casimir, gunakan layanan CasimirControlService.
CasimirControlService
Anda dapat menggunakan layanan CasimirControlService melalui REST API atau
antarmuka command line. Untuk mengetahui detailnya, lihat
Cuttlefish: Kontrol Lingkungan.
Tabel berikut menjelaskan metode di CasimirControlService. Untuk mengetahui informasi selengkapnya, lihat casimir_control.proto.
| Metode |
Deskripsi |
SendApdu
|
Mengirim byte APDU (string hex) dengan NFC-A dan ISO-DEP.
Respons ditampilkan sebagai string hex. |
Berikut adalah contoh perintah dan respons sederhana untuk mengirim dua
byte APDU, [0x00, 0x11, 0x22] dan [0x33, 0x44, 0x55].
Perintah
cvd env call CasimirControlService SendApdu '{apdu_hex_strings: ["001122", "334455"]}'
Respons sederhana
Rpc succeeded with OK status
{
"responseHexStrings": [
"9000",
"9000",
]
}

NFC is supported on Cuttlefish devices running\nAndroid 15 or higher.\n\nUse Casimir\n-----------\n\nThe Cuttlefish NFC feature uses Casimir, an external NFC device simulation tool,\nwhich supports injecting APDU bytes for host card emulation. Casimir is\nimplemented in\n[`/platform/system/nfc/tools/casimir/`](https://cs.android.com/android/platform/superproject/+/android-latest-release:packages/modules/Nfc/libnfc-nci/tools/casimir/).\n\nWhen launching Cuttlefish, Casimir is also launched by default. To\ncontrol Casimir, use the `CasimirControlService` service.\n\n### CasimirControlService\n\nYou can use the `CasimirControlService` service through the REST API or the\ncommand line interface. For details, see\n[Cuttlefish: Environment Control](/docs/setup/create/cuttlefish-control-environment).\n\nThe following table describes the method in `CasimirControlService`. For\nmore information, see\n[`casimir_control.proto`](https://cs.android.com/android/platform/superproject/+/android-latest-release:device/google/cuttlefish/host/commands/casimir_control_server/casimir_control.proto).\n\n| Method | Description |\n|------------|-------------------------------------------------------------------------------------------------|\n| `SendApdu` | Sends APDU bytes (hex strings) with NFC-A and ISO-DEP. The response is returned as hex strings. |\n\nThe following is an example command and a simplified response for sending two\nAPDU bytes, `[0x00, 0x11, 0x22]` and `[0x33, 0x44, 0x55]`.\n\n- Command\n\n cvd env call CasimirControlService SendApdu '{apdu_hex_strings: [\"001122\", \"334455\"]}'\n\n- Simplified response\n\n Rpc succeeded with OK status\n {\n \"responseHexStrings\": [\n \"9000\",\n \"9000\",\n ]\n }"]]
