WifiMulti does not support Static IP

[williamesp2015]

I am using ESP32 Arduino websocket using WifiMulti. There is example using Static IP ((https://github.com/espressif/arduino-esp32/blob/master/libraries/WiFi/examples/WiFiClientStaticIP/WiFiClientStaticIP.ino) I copied below:
#include <WiFi.h>

const char* ssid = "your_network_name";
const char* password = "your_network_password";
const char* host = "example.com";
const char* url = "/index.html";

IPAddress local_IP(192, 168, 31, 115);
IPAddress gateway(192, 168, 31, 1);
IPAddress subnet(255, 255, 0, 0);
IPAddress primaryDNS(8, 8, 8, 8); //optional
IPAddress secondaryDNS(8, 8, 4, 4); //optional

void setup()
{
Serial.begin(115200);

if (!WiFi.config(local_IP, gateway, subnet, primaryDNS, secondaryDNS)) {
Serial.println("STA Failed to configure");
}

Serial.print("Connecting to ");
Serial.println(ssid);

WiFi.begin(ssid, password);

while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}

Serial.println("");
Serial.println("WiFi connected!");
Serial.print("IP address: ");
Serial.println(WiFi.localIP());
Serial.print("ESP Mac Address: ");
Serial.println(WiFi.macAddress());
Serial.print("Subnet Mask: ");
Serial.println(WiFi.subnetMask());
Serial.print("Gateway IP: ");
Serial.println(WiFi.gatewayIP());
Serial.print("DNS: ");
Serial.println(WiFi.dnsIP());
}
/******************************/
My problem is with my project using WiFiMulti which is not supporting Static IP
WiFiMulti.addAP(SSID, pass);
Serial.print("Wait for WiFi... ");
while(WiFiMulti.run() != WL_CONNECTED) {
Serial.print(". ");
delay(500);
}

Is now any support for static IP?

[chupocro]

WiFi.config(ip, gateway, subnet);

should be after

WiFi.begin(ssid, password);

or after

wifiMulti.addAP(ssid, password);

Example of working with WifiMulti and staticIP
#include <WifiMulti.h>
//insert here your values
#define WIFI_SSID ""
#define WIFI_PASSWORD ""
IPAddress local_IP(192, 168, 1, 40);
IPAddress gateway(192, 168, 1, 1);
IPAddress subnet(255, 255, 255, 0);
void setup() {
Serial.begin(115200);
//config wifi and check
if (!WiFi.config(local_IP, gateway, subnet)) {
Serial.println("STA Failed to configure");
}
WiFi.mode(WIFI_STA);
wifiMulti.addAP(WIFI_SSID, WIFI_PASSWORD);
Serial.print("Connecting to wifi");
while (wifiMulti.run() != WL_CONNECTED) {
Serial.print(".");
delay(100);
}
Serial.println("WiFi connected.");
Serial.println("IP address: ");
Serial.println(WiFi.localIP());
Serial.println();
}

If gateway varies among different wifi APs then how can a device use static IP? I tested with 4 hotspot and two of them have same address 192.168.43.1 so I can use any adress like 192.168.43.### However, the other two hostpots have different address, resulted in showing null as IP adress in hostpot config page, at the same time prints the static ip in WiFi.localIP().
Now Im using mDNS, but it's not available on all android versions.

I have the same issue. This issue should not have been closed.

I had a simple-minded go at this, putting an on_SSID_selected(ssid) callback before WiFi.begin() in ESP8266WiFiMulti. The user can set the callback, and then invoke a suitable WiFi.config inside the callback. It seems to work.

Here is the patch.
esp8266/Arduino#9232

In my scenario (IoT sensor), I look at both the SSID and the MAC to determine the IP. There is a lot of flexibility.
