Release Date
Deliverables
- Applications can send commands to and receive responses from devices connecting via MQTT, HTTP and AMQP
- Protocol Adapters now support validation of credentials stored using the strong BCrypt hash function.
- Hono's standard MQTT adapter can now be configured as a Cloud Connector in Eclipse Kura 4.0.0.
Compatibility
There have been some changes to Hono's northbound Command & Control API:
- A new operation for sending a one-way command to a device has been added
- Hono's protocol adapters will now use an AMQP disposition frame to signal to an application the outcome of attempting to deliver a command to a device.
The classes for sending a command response from an adapter to an application have been moved from the service-base module to hono-client which also involves a change in Java package names.
