New features
- Hono services and adapters could be started locally (not in containers) for development/test purposes.
- The MQTT adapter now has experimental support for authenticating devices using the JWT based authentication scheme
employed by Google IoT Core. - The protocol adapters now have experimental support for using Google Pub/Sub as the messaging infrastructure.
Support is currently limited to publishing downstream events and telemetry messages to Pub/Sub. - The JDBC based registry now supports the Device Registry Management API's search Tenants and search Devices
operations. However, sorting and filtering is not yet implemented.
Fixes & Enhancements
- The MQTT adapter did forward command messages for devices behind a gateway when the gateway subscription was
targeting the gateway itself with topic namecommand//[<gateway-id>]/req/#. This has been fixed.
For a subscription with such a topic name, only commands for the gateway itself are forwarded, not commands for
devices, that the gateway acts on behalf of. - The LoRaWAN adapter now transforms all devEUIs hex encoded and upper case. All LoRaWAN devices should therefore be
registered upper case and hex encoded.
