Not able to assign static IP to the ESP in Station Mode?

[rameshKrSah]

I am trying to assign static IP to the ESP when it tries to connect to my WiFi network. I have used the code given below:

`void _is_esp_connected_to_wifi(void){
int status = sdk_wifi_station_get_connect_status();

while(status != STATION_GOT_IP){
	vTaskDelay(100);
	status = sdk_wifi_station_get_connect_status();

// TRACE("Connection Status: %d -- %s", status, sdk_wifi_status_2_string(status));
}

return;

}

void _station_init(void){

char ssid[] = "WCS";
char password[] = "RTSR&DWCS";
struct sdk_station_config _station_info;
struct ip_info static_ip_info = {0};


TRACE("SSID:%s, Password: %s", ssid, password);
strcpy((char *)_station_info.ssid, ssid);
strcpy((char *)_station_info.password, password);
_station_info.bssid_set = 0;

//Delete all existing wifi stuff in the EEPROM
sdk_wifi_station_disconnect();
sdk_wifi_set_opmode(NULL_MODE);
dhcpserver_stop();
vTaskDelay(500);

IP4_ADDR(&static_ip_info.ip, 192, 168, 5 ,55);
IP4_ADDR(&static_ip_info.gw, 192, 168, 5, 1);
IP4_ADDR(&static_ip_info.netmask, 255, 255, 255, 0);
TRACE("static ip set status : %d", sdk_wifi_set_ip_info(STATION_IF, &static_ip_info));
vTaskDelay(50);

//Must call sdk_wifi_set_opmode before sdk_wifi_station_set_config
sdk_wifi_set_opmode(STATION_MODE);
sdk_wifi_station_set_config(&_station_info);
sdk_wifi_station_connect();
_is_esp_connected_to_wifi();
TRACE("ESP Connected to WiFi %s", ssid);

}

void station_connect(void *pc){
struct ip_info get_static_ip = {0};

_station_init();
sdk_wifi_get_ip_info(0, &get_static_ip);
TRACE("Obtained IP Address: %d.%d.%d.%d",ip4_addr1(&get_static_ip.ip),
		ip4_addr2(&get_static_ip.ip),ip4_addr3(&get_static_ip.ip),ip4_addr4(&get_static_ip.ip));
while(1){
	vTaskDelay(1000);
	TRACE("static ip test ");
}

vTaskDelete(NULL);

}

void user_init(){
// sdk_system_update_cpu_freq(SYS_CPU_160MHZ);

#if 1
//sdk_wifi_set_opmode(NULL_MODE);
//sdk_wifi_station_set_auto_connect(0);
#endif

#if ENABLE_DEBUG == 1
uart_set_baud(0, 74880);
iomux_set_function(gpio_to_iomux(2), IOMUX_GPIO2_FUNC_UART1_TXD);
#endif

TRACE("SDK Version: %s", sdk_system_get_sdk_version());
TRACE("Free Heap Size: %d", sdk_system_get_free_heap_size());
TRACE("Chip ID: %d", sdk_system_get_chip_id());
TRACE("user_init running for static ip test ....");

xTaskCreate(station_connect, "station", 500, NULL,14, NULL);

}`

Also the dhcp server keep on running, although i have stopped it in the above code .

Is this the right way of doing this and if not can someone point it out what am I doing wrong. Thanks.

I don't think a static IP address ever worked for a station, but an attempt to fix it has been made in the rewrite for lwip v2 in #389

Much of the logic seems to be in open_esplibs/libwpa/wpa_main.c:sdk_eagle_auth_done() see the trailing code in that function, so if you are still seeing problems then perhaps you could trace the logic there. The start/stop functions are in libmain/user_interface and might need some work too.

@ourairquality thanks for your reply and you are right that much of the logic is in the c files, user_interface.c and wpa_main.c. And I have a good news, after an hour of more fiddling, I have successfully assigned static IP to the esp. I have checked the program for different IPs and it worked all fine. Here is the code fragment:
