Firmware release notes

YuDash V4.6

  1. Release date: 14 November 2024

  2. Enhanced Ethernet setup and retry feature to check ethernet link status. This is primarily applicable for on-premise and peer-to-peer communication.

  3. SD card Data logging with "useDefaults" feature.

    1. With useDefaults enabled, SD card logging will be enabled all parameters (maximum 16) with first column as timestamp. The logger file is created on per-day basis in directory "/logger_dir".

    2. User can provide partial settings and other parts will be taken as default.

  4. Bugfix of variables clash when both Lan UI and Modbus server is enabled.

  5. Support of upto 20 variables in Modbus server.

  6. Support of upto 30 variables in LAN UI server.

  7. Beta version of serverMode.

    1. serverMode is applicable with timeSync feature along with YuDash device acting as Modbus server.

    2. The input instruments are read continuously for real-time refresh to Modbus server. This is similar to loopDelay=0.

    3. Data push to cloud and SD card logging is done as per timeSync value.

  8. Sub Firmware Versions:

    1. 4.62: YuDash LYNX

    2. 4.60: YuDash ZENYX

    3. 4.67Q: YuDash LYNX with Quectel 4G module.

    4. 4.65Q: YuDash ZENYX with Quectel 4G module

YuDash V4.5

  1. Release date: 13 October 2024

  2. Enhancement for SD card mounting error and retries.

  3. Enhanced Modbus RS485 server to avoid read errors.

  4. Sub Firmware Versions:

    1. 4.52: YuDash LYNX

    2. 4.50: YuDash ZENYX

    3. 4.57Q: YuDash LYNX with Quectel 4G module.

    4. 4.55Q: YuDash ZENYX with Quectel 4G module

YuDash V4.4

  1. Release date: 1 August 2024
