• Bug fixes:
  • When APP firmware is uploading using the configuration Tool and Board is power off, the product not operate.
  • DHCP Lease Time : when DHCP_DEBUG enable, DHCP Lease Time is fixed as 10 second.
    • DHCP lease time is modified to use it that information of received packet from DHCP Server.
  • The Status LED(PA_07) of WIZ750SR_1xx doesn't operate.
    • The Status LED(PA_07) of WIZ750SR_1xx is modified. Turning on an LED and making it blink once per second.
  • Compare DHCP Server IP : When DHCP OFFER Packet receive from DHCP Server,the DHCP server ip in packet compare with previous DHCP Server IP.
• Improvements:
  • The ISR address have changed to fixed address. The ISR address of APP did no more have to need copy and use in Boot.

• Bug fixes:

  • If serial data packing 'time' option is less than 500ms, the first serial data(+++) ignored in GW mode.
  • When UART Tx/RX cross connect and Received UART data size more than 3, UART data don't send .

• Improvements:

  • While IP address is allocating using DHCP ,
    • the device can be made searchable using the Configuration tool and it can change the mode(AT mode <-> GW mode).
      • It can change the AT mode. It can show that the status of channel change from ATmode to OPEN in Configuration tool. So AT command didn't operate and this bug fixed
