1. First, confirm whether 192.168.10.202 is an illegal IP. If this IP exists, it may be because the output parameter ip->type of tkl_wifi_get_ip is not set.
2. Check if port 6668 has been bound.
3. Make sure the IP returned by the tkl_wifi_get_ip interface is the same as the IP returned by tkl_wired_get_ip. If only using wired, tkl_wifi_get_ip should directly return a non-zero number, such as -1.
4. If using the demo directly, confirm the tkl_wired_get_ip interface. There is a slight issue with the demo; NW_IP_S should not be cleared.
