Describe I used Wireshark and did not find any DHCP packets from the MXCHIP chip.

Hi @gavin-hy,

this log is the trace of the EMW3080 Wi-FI module configured in stack-bypass mode. The module reports it successfully joined the "321" SSID with "12345678" password.

Since the TCP-IP stack runs on the host rather than on the module, it is expected that the module does not report the IP configuration of the device.

If the DHCP client fails to start, the LwIP instance running on the should be investigated.

In case you forked and modified the host application, it would be worth testing with the latest release tag.
