Update History

v1.2.4 Stable

• Bug fixes:

  • Serial data packing 'time' option does not work if serial command mode switching code is disabled.
  • Fixed typo of debug message

• Improvements

  • Added the PHY init stabilization code
  • Restore TCP connection status function to Status Pin (WIZ750SR-100/105/110 only)
    • The Status pin now acts as an 'HW_Trigger' pin(Input at booting) and a TCP connection status pin(output).

v1.2.3 Stable

• Bug Fixes:

  • Fixed an issue where the pin states could not be saved correctly if the user's GPIO is set to 'Digital Output'

• Improvements:

  • From this version, AppBoot mode supports TCP unicast search function
    • Until the previous version, AppBoot mode only supported the UDP search function
    • This is an enhancement to enable firmware update even in device control using TCP unicast search function in new configuration tool

• Changes:

  • The function of the STATUS pin that was responsible for the TCP connection status indicator function has been changed to Command mode switch trigger pin (HW_Trigger).
    • This changes only apply to the WIZ750SR-1xx product family (WIZ750SR-100/105/110, change to maintain compatibility with WIZ100SR)
    • The HW_Trigger pin up to v1.2.2 will no longer work with v1.2.3. The STATUS pin acts as the HW_Trigger.

v1.2.2 Stable

• Bug Fixes:
  • Stabilize the network operation of the W7500P devices
  • Error in setting function in App_Boot mode due to 'TR', 'SC' command processing failure
  • Applied the missing TCP retransmission timeout-value change

v1.2.2 Pre-release

• Bug Fixes:

  • Internal bug fixing (PHY init)
  • Char serial packing option(delimiter) setting does not correctly apply some hex codes

• Improvements:

  • Changed the location of the flash erase operation function during network firmware update
    • Now the application area flash memory is erased after socket establishment of TCP connection for the firmware update
  • Extended serial debug message added:
    • If this option is selected, users can check the sent and received data via the serial debug port. (WIZnet S2E tool GUI version 0.4.0 or later)

• Changes:

  • Changed the TCP retransmission timeout-value from 250ms to 200ms(return to default value)
    • The TCP timeout can be adjusted by the TCP retransmission retry count added in firmware version 1.2.0.

v1.2.1

• Improvements:
  • Enhanced operational stability when performing configuration data save and factory reset functions

v1.2.1 Pre-release

• Bug Fixes:
  • 'Character' of serial data packing option is not set correctly

v1.2.0

• Bug Fixes:
  • Data loss problem due to unintended delay in RS-485 mode (WIZ750SR-RS485 only)
  • Incorrect command processing problem: If the processing of a command set containing unsupported commands via Ethernet is sent to WIZ750SR, the device only responds a result until the error occurs
• Improvements:
  • Command added:
    • TR: TCP retransmission retry count adjustment function(WR, param range: 1 ~ 255)
    • BU: AppBoot update function (WO)
  • Changed the firmware update mechanism:
    • The app-backup area is no longer used and flash update operation is only performed in AppBoot mode
  • Now an error message about command processing will be output only during serial command mode operation
• Known Issues:
  • 'Character' of serial data packing option is not set correctly
    • This issue will be fixed in firmware version 1.2.1

v1.1.2

• Bug Fixes:
  • MAC address changed problem when device settings are saved (very occasionally)
  • Delayed response to search in config-tool when connecting to server in TCP client mode
  • Force socket close when fw update fails occurred
• Improvements:
  • Supports serial baudrate up to 460.8kbps
  • Added device profiles of WIZ750SR-1xx series to project source code

v1.1.1

• Bug Fixes:
  • Firmware update timeout function error in AppBoot mode
  • 10M Ethernet fixed error (W7500P only)
  • Invalid parameter of FW command (firmware update)
• Improvements:
  • Command added: AppBoot mode switching function(AB)
  • Initial boot latency(1500ms) has been removed

v1.1.0

• First release : 2016
