MQTT

MQTT (MQ Telemetry Transport atau Message Queue Telemetry Transport) merupakan standar ISO (ISO/IEC PRF 20922) berbasis publish-subscribe yang ringan dan dapat bekerja pada protokol TCP/IP. Ada 5 metode MQTT yaitu Connect, Disconnect, Subscribe, Unsubscribe, dan Publish.

  • Connect: Menunggu sampai koneksi dibangun dengan server .

  • Disconnect: Menunggu client MQTT untuk menyelesaikan tugasnya, dan juga menunggu pemutusan sesi TCP/IP.

  • Subscribe: Meminta server untuk unsubscribe pada satu atau banyak topik.

  • Unsubscribe: Meminta server untuk unsubscribe pada satu atau banyak topik.

  • Publish: Kembali ke thread aplikasi setelah melempar request ke client MQTT.

Topic

Komunikasi MQTT didasari oleh topik. Topik digunakan untuk memisahkan satu kanal komunikasi dengan kanal lainnya. Spesifikasi teknis oneM2M sudah menyediakan topik khusus yang harus digunakan untuk komunikasi MQTT. Publikasi harus dilakukan pada topik yang spesifik dan respons juga akan diberikan pada topik berbeda yang sudah disediakan sebelumnya.

Publish/Request topic

Bentuk topik request:

/oneM2M/req/your-access-key/antares-cse/choose-a-serialization-format

Subscribe/Response topic

Bentuk topik respons:

/oneM2M/resp/antares-cse/your-access-key/choose-a-serialization-format

Note

your-access-key adalah access key akun anda. choose-a-serialization-format dapat berisi 2 nilai:

  • xml untuk format XML

  • json untuk format JSON

MQTT Payload

Payload yang dikirim ke topik MQTT adalah RequestPrimitive dan ResponsePrimitive yang telah dilakukan serialisasi. Data-data dikirimkan pada RequestPrimitive dan yang nantinya akan diterima oleh ResponsePrimitive.

Beberapa parameter utamanya adalah:

pc

Primitive Content

Konten request (contoh: resource untuk dibuat)

ty

Type

Tipe resource untuk dibuat

rsc

Response Status Code
