---

Bug fixes:

• Serial data packing 'time' option does not work if serial command mode switching code is disabled.
• Fix 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).

  • WIZ750SRv123.bin (App only)
  • WIZ750SRv123_incl_Boot.bin (Boot+App)

---

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 the 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

Attached binaries

• WIZ750SR-TTL / RS232 / RS485

  • WIZ750SRv122.bin (App only)
  • WIZ750SRv122_incl_Boot.bin (Boot+App)

• WIZ750SR-100 / 105 / 110

  • WIZ750SR-1xxv122.bin (App only)
  • WIZ750SR-1xxv122_incl_Boot.bin (Boot+App)

* WIZnet S2E config-tool supports firmware update function of application area only. (App only) If you want to program the 'Boot+App' firmware on your device, please use the W7500(P) ISP tool.

---

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 Stable

Improvements

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

Attached binaries

• WIZ750SRv121.bin: App firmware binary for WIZ750SR-TTL / RS232 / RS485
• WIZ750SR-1xxv121.bin: App firmware binary for WIZ750SR-100 / 105 / 110

v1.2.1 Dev

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 Dev

Bugfix:

• modify library in uart.c

Improvements:

• Added WIZ750SR-1xx series codes. (for W7500)
• Added WIZ750SR-1xx RTS control function for flow control.

v1.1.2 Stable

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 F/W update fails occurred

Improvements:

• Supports serial baud rate up to 460.8kbps
• Added device profiles of WIZ750SR-1xx series to project source code

v1.1.1 Stable

Bugfix:

• 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
