Buat manifes decoder ()AWS CLI

Anda dapat menggunakan operasi CreateDecoderManifestAPI untuk membuat manifes decoder. Contoh berikut menggunakan AWS CLI.

penting

Sebelum Anda membuat manifes decoder, buat model kendaraan terlebih dahulu. Untuk informasi selengkapnya, lihat Buat model kendaraan.

Untuk membuat manifes decoder, jalankan perintah berikut.

Ganti decoder-manifest-configurationdengan nama file JSON yang berisi konfigurasi.

aws iotfleetwise create-decoder-manifest --cli-input-json file://decoder-manifest-configuration.json

Manifes decoder dengan konfigurasi antarmuka CAN

• Ganti decoder-manifest-namedengan nama manifes decoder yang Anda buat.

• Ganti Vehicle-model-ARN dengan Amazon Resource Name (ARN) dari model kendaraan.

• (Opsional) Ganti deskripsi dengan deskripsi untuk membantu Anda mengidentifikasi manifes decoder.

Manifes decoder dengan konfigurasi antarmuka middleware kendaraan

• Ganti decoder-manifest-namedengan nama manifes decoder yang Anda buat.

• Ganti Vehicle-model-ARN dengan Amazon Resource Name (ARN) dari model kendaraan.

• (Opsional) Ganti deskripsi dengan deskripsi untuk membantu Anda mengidentifikasi manifes decoder.

Urutan node properti dalam struktur (struct) harus tetap konsisten seperti yang didefinisikan dalam katalog sinyal dan model kendaraan (manifes model).
