Versions and Release Notes

Version 1.6.2 (April 3, 2019)

Release Summary

Two years passed since I got my first IoT DevKit prototype in hand (5 in total), and now tens of thousands of people are playing with it.

SPI

Love and struggle, it’s my feeling and also feedback from all of our lovely customers, RESONANCE. We’re keeping improving this lovely board: add new functions, improve the SDK, add new examples, build new development tool - IoT Device Workbench extension for VS Code, and also try our best to help people in the chat room.

Now another spring, another step forward, let’s have SDK released for the lovely board and all lovely customers.

  • Fix all build warnings pump up from underlying RTOS and libraries.
  • Support un-sorted server cert chain during TLS handshake, this is part of TLS 1.3 feature.
  • Upgrade Azure IoT C SDK to 1.2.14.
  • Remove the path information from the system error which is bothering everyone and may case people feel uncomfortable.
  • Support customzied WebServer for system configuration: WiFi setting, IoT Device Connection String setting and X.509 cert setting.
  • Support customized time server.

Thanks everyone for using and supporting us! Please try 1.6.2 and any feedback will be appreciated.

Version 1.6.0 (December 19, 2018)

Release Summary

Happy holidays, everyone! This is a minor version increase of our IoT DevKit SDK!

  • Upgrade Azure IoT C SDK to 1.2.10, which is the most latest version, and much stable than old version.
  • Release the polished WebSocket library.

  • Fixed the SPI library. Sorry for finding this issue so late. This is not only the software bug but also circuit issue, so if you want to use the extern SPI pins please remove one resistor as bellow:

    SPI

    The extern SPI is shared with the built in codec chip, so there have one pin conflict. Remove this resistor can solve the SPI issue but the codec can’t work well, that means you can’t use any Audio functions if enable the extern SPI, vice versa.

Special thanks to Sean Kelly for polishing the WebSocket library and Xavier Geerinck found the SPI issue, thank you for your contributions and feedbacks.

  • SDK
    • Update the Azure IoT DPS SDK to 1.2.8 to support DPS group enrollment.
    • Fix the memory leak caused by GetHostNameFromConnectionString.
    • Make the SystemTickCounterRead thread safety.
    • Fix the file system example.

Version 1.4.1 (August 6, 2018)

Release Summary

  • SDK
  • 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.

Downloads

Version 1.4.0 (July 19, 2018)

Release Summary

  • 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 one-click installation package.

    • A new version of the Audio driver library (AudioClassV2) has been added. This new version supports call-backs, allowing you to greatly simplify Arduino sketches which need to monitor and react to the current audio state as, for example, when it changes from AUDIO_STATE_RECORDING to AUDIO_STATE_PLAYING. An example Arduino sketch making use of this new feature may be found in the Audio2 folder under “Examples for MXCHIP AZ3166”. Note: The previous AudioClass library has been retained for backward compatibility with legacy sketches. (Sample sketches utilizing the AudioClass.h library may be found in the Audio folder under “Examples for MXCHIP AZ3166”.) Provide V2 version of Audio driver library to support callback in record and play.
    • A name conflict (INADDR_NONE) in source code was generating the error “Expected ‘)’ before numeric constant”. This error (documented in Issue 169) has been corrected.
