User Guide on Eclipse Hono™ Vers.: 2.7

Device Registry

Mon, 01 Jan 0001 00:00:00 +0000

The Device Registry component provides implementations of Hono’s Tenant API, Device Registration API and Credentials API. Protocol adapters use these AMQP 1.0 based APIs to determine a device’s registration status during runtime. For example, when a device tries to connect to a protocol adapter, the adapter uses information retrieved from the device registry to check if the device is enabled, whether the tenant that it belongs to requires devices to authenticate before accepting any data from it and if so, for verifying the device’s credentials.

In addition to the above APIs, the Device Registry also exposes HTTP endpoints for managing the content of the registry according to the Device Registry Management API. This API is used by administrators to create and configure tenants and provision devices into the system. Without these steps, no devices can connect to any of Hono’s protocol adapters. The Device Provisioning concept page describes the steps necessary to manually provision a device and also provides information about how devices can be provisioned automatically based on X.509 client certificates.

HTTP Adapter

Mon, 01 Jan 0001 00:00:00 +0000

The HTTP protocol adapter exposes HTTP based endpoints for Eclipse Hono™’s south bound Telemetry, Event and Command & Control APIs.

MQTT Adapter

Mon, 01 Jan 0001 00:00:00 +0000

The MQTT protocol adapter exposes an MQTT topic hierarchy for publishing telemetry data and events to downstream consumers and for receiving commands from applications and sending back responses.

AMQP Adapter

Mon, 01 Jan 0001 00:00:00 +0000

The AMQP protocol adapter allows clients (devices or gateway components) supporting the AMQP 1.0 protocol to publish messages to Eclipse Hono™’s Telemetry, Event and Command & Control endpoints.

CoAP Adapter

Mon, 01 Jan 0001 00:00:00 +0000

The CoAP protocol adapter exposes CoAP based endpoints for Eclipse Hono™’s south bound Telemetry, Event and Command & Control APIs.

Sigfox Adapter

Mon, 01 Jan 0001 00:00:00 +0000

The Sigfox protocol adapter exposes an HTTP endpoint for connecting up with the Sigfox backend for publishing telemetry, events and use command & control.

File Based Device Registry

Mon, 01 Jan 0001 00:00:00 +0000

The Device Registry component provides exemplary implementations of Hono’s Tenant API, Device Registration API and Credentials API.

Kura Adapter

Mon, 01 Jan 0001 00:00:00 +0000

The Kura protocol adapter exposes an MQTT topic hierarchy allowing Eclipse Kura™ based gateways to publish control and data messages to Eclipse Hono™’s Telemetry and Event endpoints.
