Technical Changes

wizcmdset.py

• Moved IP20 to W55RP20_CMDSET branch (from WIZ5XX_RP_CMDSET)
• Added IP20 to firmware version check logic
• Extended BR (Baudrate) index support to 0-19

main_gui.py

• Added IP20 to W55RP20_FAMILY tuple
• Extended baudrate UI configuration (460800, 921600, 1M, 2M, 4M, 8M)
• Improved EB (channel 2 baudrate) handling for 2-port devices
• Enhanced baudrate selection logic

Supported Devices

• W55RP20-S2E: up to 8Mbps (FW >= 1.2.1) or 460.8kbps (FW < 1.2.1)
• W55RP20-S2E-2CH: up to 8Mbps (FW >= 1.2.1) or 460.8kbps (FW < 1.2.1)
• IP20: up to 8Mbps (FW >= 1.2.1) or 460.8kbps (FW < 1.2.1)
• WIZ750SR, WIZ750SR-1xx: up to 230.4kbps
• W232N: up to 230.4kbps
• Other WIZnet S2E devices: up to 921.6kbps

Notes

High-speed baudrates (1Mbps and above) require firmware v1.2.1 or later for W55RP20 series and IP20 models.

Full Changelog: v1.5.8.1...v1.5.8.3

v1.5.8.1

Enable SSL TCP Client and MQTTS Features on IP20 Devices

v1.5.8

WIZ750SR Series Modbus MB Parameter Support and Build Script Improvements

• WIZMakeCMD.py: Added Modbus MB parameter support for WIZ750SR series (firmware 1.4.4+), renamed WIZSPE-T1L to WIZ750SR-T1L
• main_gui.py: Refactored Modbus support logic with automatic MB/PO parameter selection
• wizcmdset.py: Added version-based command set dynamic application
• build.ps1: Improved build script stability with PyInstaller auto-install check

v1.5.7.2

Added support for WIZSPE-T1L device(operates identically to WIZ750SR-1xx series)

v1.5.7.1

Bug Fixes:

• Fixed device selection defaulting to Options tab instead of Basic Settings tab
• Fixed Factory Reset button toggle state issue (button no longer stays highlighted after click)

v1.5.7

What's New

Added Connection Data Parameters for W55RP20-S2E, W232N, and IP20 devices

• New "Send Data at Connection", "Send Data at Disconnection", "Ethernet Data Connection Condition"
• All parameters support up to 30 characters
• Only available for firmware v1.1.8 and above

UI Improvements

• Added dedicated panels for connection data configuration
• Increased minimum window size to 950x850 for better visibility

v1.5.6.3

Bug fixes:

• Fixed an issue where “W55RP20-S2E” and “W232N” devices could not properly handle the Modbus (PO) parameter.
  1. Changed wizcmdset.py so PO is “RW” instead of “RO,” reflecting actual firmware behavior.
  2. Updated WIZMakeCMD to always include PO for W55RP20-S2E and W232N, and only for WIZ5XXSR if firmware ≥ v1.0.8.
  3. Revised object_config_for_device() and get_object_value() so W55RP20-S2E and W232N always allow Modbus settings, while WIZ5XXSR still requires firmware ≥ 1.0.8.
  4. Added if "PO" in dev_data: logic in fill_devinfo() to correctly read and display PO values in the GUI’s Modbus ComboBox.

v1.5.6.2

1. Enhanced High DPI Support

• Improved UI scaling under Windows display magnifications (150%–200%).

2. Redesigned “Network Interface Config” Menu

• Added a “Refresh” feature under the top “Network Interface Config” menu, allowing manual refresh when IP addresses or network adapters change.

3. Other UI Improvements and Bug Fixes

• Added a placeholder (<Select Network Interface>) to the ComboBox to avoid exceptions (e.g., IndexError) when an invalid network interface is selected.
• Strengthened error messages and logging if a connection issue arises during device searches.

v1.5.6.1

Baud rate adjustments: W232N limited to 230400, W55RP20-S2E supports up to 921600

v1.5.6

Enhancements:

• Added support for "W55RP20-S2E" and "W232N" devices in the WIZMakeCMD.py.
• Implemented device-specific search and configuration command handling for newly supported boards.
• Enhanced UI initialization and configuration settings across various functions in main_gui.py to accommodate new device types.
