Data mode not working on WIZ550S2E

Question

Hi! I’m trying to connect my MSP432 microcontroller to a TCP server (Hercules) using WIZ550S2E. I configured the module as a DHCP client. The problem is that after switching to data mode, it does not transmit data received from UART or from Ethernet (TCP server). I have attached a logic analyzer capture which can be opened using the free Salae Logic Pro software. You can see that after switching to data mode, it replies success “[S]
”, but the data sent over UART (“abc”) does not reach the TCP server. Vice versa is the same. If I remain in AT command mode, I can send/receive data successfully, but I need to work in transparent mode. I’ve tried connecting using the AT configuration tool v1.03, but it cannot find the device. I have connected the module directly to the PC. Module IP is 192.168.11.100, PC IP is 192.168.11.101, ping works, firewall is disabled, but AT configuration tool cannot find it. What is the problem? Is there a configuration missing? **capture.zip (4.4 KB) **

Hi. I replyed to other place. WIZ550S2E not reconnecting to TCP server WIZ550 Series Hi. Sorry, It don’t open capture file. Is it wireshark tool file? please refer to wireshark file to me. I want know your all configuration system diagram or real pictures. Are you normal working configuration tool search? Then It is normal working. Therefore, Which use to serial system?(rs232 or rs485) Or you have to checking to configuration network setting (IP, subnet mask, gateway, port). Please tell me all information. Thank you. Thank you.
