WIZ550S2E->WIZ550S2E_Boot->ConfigData.c

for(i = 0, j = 0 ; i <= 6 ; i++, j += 2) s2e_packet.network_info_common.mac[i] = get_hex(buf[j], buf[j+1]);

When i=6 and j=12, both .mac[i] and buf[j] will go out of bounds. I was alerted by a compiler warning in LPCXpresso 8.2.2.

Does this break the bootloader, or does in field flashing still work?
Which version of LPCXpresso are you using for compiles?

Is it possible to programm a 3964R DUST Protocoll to the WIZ550S2E?
Description of the protocoll: https://de.wikipedia.org/wiki/3964R
Fragments of C/C++ Code: https://www.c-plusplus.net/forum/42820-full

FW is written for default MAC address provided by WIZNET, if you change the MAC Address, you will need to change the FW to take care of this.

/* Check MAC Address */
check_mac_address();

This call - check_mac_address() will need to modified.

See suggested change below,, 0xAA, 0xBB, 0xCC should be reflective of your mac address prefix assigned to you.
code fragment that needs to changed shown below

if(s2e_packet.network_info_common.mac[0] != 0xaa || s2e_packet.network_info_common.mac[1] != 0xBB || s2e_packet.network_info_common.mac[2] != 0xCC) {
printf("Input MAC ? ");

//================================
Make a change to the ConfigData.c

void set_S2E_Packet_to_factory_value()
{
//
...
// enter your default MAC ID you want to reset for your module.
s2e_packet.network_info_common.mac[0] = 0xAA;
s2e_packet.network_info_common.mac[1] = 0xBB;
s2e_packet.network_info_common.mac[2] = 0xCC;
s2e_packet.network_info_common.mac[3] = 0xDD;
s2e_packet.network_info_common.mac[4] = 0xEE;
s2e_packet.network_info_common.mac[5] = 0xFF;
//
...
//
}

To change of Port, Setting Password, Connection Password, Module Name in at-command mode

I am using FW Version 1.03 and older versions. By default the device does not connect to a socket say 5000 and communicate. I am using the Development board with a WIZ550S2E module. When entering the AT Mode, I am able to open a socket, and receive data from the Ethernet port. When I close the AT+MDATA comms, I cant send data to the ethernet side. Putty closes the connection, on RAW Socket comms or TELNET to port 5000.

if the Module is a Serial to Ethernet Device (Serial TTL / RS232 / RS485/422) it should start to function like one from power up after the necessary initialization.
(Surely I am missing something.. my experience with WIZNET has been very satisfactory.)

Hello,

Can I ask you, is it possible send POST (GET) reguest to the web server form WIZ550S2E module?

Thanks

Hello,

One of my customers wanted to change the connection mode, for example from Server mode to Client mode, or the destination IP and port number in command mode and then let WIZ550S2E try to connect with information he changed when I come out to data mode.
But it looks impossible because WIZ550S2E doesn't have any command for this.

Please implement new command for this.

Thank you.

Hello,
I try compile the Firmware projects for WIZ550S2E, everything was OK. After update to module one status LED is blinking and if I send some command via SERIAL then second status LED is on for cca 1sec and then is off and no answer from module. If I update back to version 1.0.0 then communication is OK.
Can You help me with this??
Thanks
Best Regards

Hello,
Can I ask you if is possible change the REMOTE PORT via AT command?
Because, If I send command "AT+FDNS=xxxxxx" then returned IP address is automatically entered into HOST IP - It is OK
But if I want to change the remote port it must do via config tools.
I need send data to 3 different servers with different ports:
AT+FDNS=xxxxxx port xxxx
AT+FDNS=yyyyy port yyyy
AT+FDNS=zzzzzz port zzzz

Thanks For your help
Best Regards

I upgraded the WIZ5500S2E module to v1.1.2. It has an LPC1136E microcontroller. How to use MQTT library for it?

https://forum.wiznet.io/t/topic/3736

Hi if I send for example not correct address AT+FDNS=www.google.c, or not connected to internet, then the timeout of DNS never not occure. Then I must reset the module, becouse is freeze.

It is possible change some code to repair it?
I use FW version 1.1.4.

Thanks
