Hi,

[quote user=""]there will be error in log: that is 30 seconds gaps and shows error, also it will not connect to router.[/quote]

Try setting:

CONFIG_NET_CONFIG_INIT_TIMEOUT=0

[quote user=""]

2. and if i set CONFIG_NET_DHCPV4=y

the static ip address setting will be overwrite by dhcp:

This is expected when DHCP client is enabled.

To set static ip, you can use wifi/sta as an example.

You will need to change the dhcp function in main.c to something like this:

static void print_dhcp_ip(struct net_mgmt_event_callback *cb)
{
#if defined(CONFIG_NET_DHCPV4)
	/* Get DHCP info from struct net_if_dhcpv4 and print */
	const struct net_if_dhcpv4 *dhcpv4 = cb->info;
	const struct in_addr *addr = &dhcpv4->requested_ip;
	char dhcp_info[128];

	net_addr_ntop(AF_INET, addr, dhcp_info, sizeof(dhcp_info));

	LOG_INF("DHCP IP address: %s", dhcp_info);
#endif
}

And in prj.conf, you explicitly disable dhcp:

CONFIG_NET_DHCPV4=n

And set your wanted IP address on the network that you're connecting to:

CONFIG_WIFI_CREDENTIALS_STATIC_SSID="MY_SSID"
CONFIG_WIFI_CREDENTIALS_STATIC_PASSWORD="MY_PASSWORD"

CONFIG_NET_CONFIG_MY_IPV4_GW="192.168.32.1"
CONFIG_NET_CONFIG_MY_IPV4_ADDR="192.168.32.9"

My network is on 192.168.32.xxx

On a test-laptop, connected to the same network, I can then ping 192.168.32.9:

$ ping 192.168.32.9
PING 192.68.32.9 (192.168.32.9): 56 bytes
64 bytes from 192.168.32.9: icmp_sec=1 ttl=64 time=53.068 ms

Kind regards,
