1.5.0 (2023-01-10)

Features Added

  • [#2443] Adding IoT Device Provisioning support for Custom Allocation Payload.
    • New APIs: az_iot_provisioning_client_register_get_request_payload() and az_iot_provisioning_client_registration_state.payload.

Bugs Fixed

  • [#2437] Update ADU device information payload to GA key/values.
  • [#2443] Azure IoT Samples now display errors following the source file:line number format, allowing Visual Studio Code to automatically create links from the output log.

Other Changes

  • Azure IoT Device Provisioning Client API deprecation: az_iot_provisioning_client_get_request_payload() is deprecated in favor of az_iot_provisioning_client_register_get_request_payload(). The new API requires an initialized az_iot_provisioning_client_payload_options structure (using az_iot_provisioning_client_payload_options_default()).

1.2.0 (2021-09-08)

Features Added

  • Add az_iot_provisioning_client_get_request_payload() to create MQTT payload bodies during Device Provisioning.
  • This version provides new APIs to follow the IoT Plug and Play convention to implement Telemetry, Commands, Properties and Components defined in a DTDL model.
    • To read/write properties, the SDK now provides functions to produce the right payload for components, as shown in the header azure/iot/az_iot_hub_client_properties.h.
    • To send telemetry messages, the required header is added to identify components.
    • When responding to a command invocation the component name is automatically parsed and provided when available.
    • All new samples follow the IoT Plug and Play convention and can be connected to IoT Hub (with or without DPS), or IoT Central.

Bugs Fixed

  • [#1905] Fix the internal state of the JSON writer during calls to az_json_writer_append_json_text() by taking into account the required buffer space for commas. (A community contribution, courtesy of hwmaier)

1.2.0-beta.1 Pre-release
Pre-release

1.2.0-beta.1 (2021-07-09)

New Features

  • Added a current depth field to the JSON reader.
  • Added base64 encoding and decoding APIs that accept az_span, available from the azure/core/az_base64.h header.
  • Public preview version of a new set of APIs to simplify the experience using Azure IoT Plug and Play. To consume this new feature, the az::iot::hub CMake target has been updated. The APIs can be found in the header files: az_iot_hub_client.h and az_iot_hub_client_properties.h.
  • New samples showing how to consume the new IoT Plug and Play APIs:
    • paho_iot_pnp_component_sample.c
    • paho_iot_pnp_sample.c
    • paho_iot_pnp_with_provisioning_sample.c

Bug Fixes

  • [#1640] Update precondition on az_iot_provisioning_client_parse_received_topic_and_payload() to require topic and payload minimum size of 1 instead of 0.
  • [#1699] Update precondition on az_iot_message_properties_init() to not allow written_length larger than the passed span.
