Devkit SDK 1.4.1

• SDK

  • Add OTA Programming API.

  • UARTClass class support extra serial port (PB_6 & PB_7).

  • Audio class support automatic level control on microphone.

• Mini Solution
  • Add IoT DevKit firmware OTA update mini solution.

  Notice: Please make sure you have upgrade the firmware before running the OTA mini solution.

• Special thanks to capfish , Adamantinu and Chris Lovett, thank you for your contributions and feedbacks.

Devkit SDK 1.4.0

• Firmware

  • Enable firmware update capability in bootloader.
    Now the bootloader can upgrade the firmware from the on-board SPI flash, this is part of the OTA programming (firmware update) feature.
    By integrating with the Azure Automatic Device Configuration service, the OTA firmware update function will be enabled in next release.

• SDK

  • Reduce the size of file system which builds upon the 2MB on-board SPI flash.

    Notice: Because it need more on-board SPI flash space to store the new firmware for firmware updating, we reduced the space of file system. So if you have files on IoT DevKit, please make sure they have been well backed up before upgrade to this new SDK.

  • Add setVolume API to support change the audio volume.

• Mini Solution

  • Update the DevKit Translator to use the new Audio APIs.

• Development Tools

  • Deprecate existing one-click installation package.
    Our new VS Code extension: IoT Workbench can provide better development experience for IoT DevKit, you can install it from the VS Code marketplace directly and follow this tutorial to start using IoT DevKit.

    So starting with 1.4.0 we only provide the Arduino board package (SDK only) and no longer to have the on-click installation package.

• Special thanks to Oguz Bastemur, thank you for your contributions and feedbacks.

DevKit SDK 1.3.5

• SDK

  • Add Watchdog Timer API.
  • Add External Interrupts API.
  • Fix MQTT client reconnect issue.
  • Filter out DevKit hotspot in the WiFi configuration page.
  • Fix bugs.

• Mini Solution

  • New mini-solution: Connect to IoT Edge device gateway as Modbus TCP device.

• Development Tools

  • Fix bug such that it works for users who only have resource group-level access
  • Fix azure-cli bug by updating azure-cli to latest version.
  • Allow users to disable data collection.

• Special thanks to Kirk Munro , fmuntean , Thomas Mutzl, thank you for your contributions and feedbacks.
