Problem Description

When I upload this sketch to my NodeMCU I see that WiFi.status() always returns WL_CONNECTED after a call to WiFi.config(...) and it doesn't if WiFi.config(...) is commented out. I use "Erase Sketch + WiFi settings" (option from arduino IDE's menu) each time I flash this sketch.
Even if i put a delay(1000) after WiFi.config(...) it doesn't work. Is it a bug?
Couldn't try the sketch with the latest git because it fails (it says it cannot execute "tools/python3/python3" if I understood correctly)

MCVE Sketch

#include <Arduino.h>
#include <ESP8266WiFi.h>

void setup() {
  Serial.begin(9600);
  Serial.println()
  Serial.println("Hello!");
  
  WiFi.mode(WIFI_STA);
  WiFi.config(IPAddress(192, 168, 1, 50), IPAddress(192, 168, 1, 1), IPAddress(255, 255, 255, 0));
  if (WiFi.status() == WL_CONNECTED) {
    Serial.println("Connected!");
  } else {
    Serial.println("Not connected!");
  }
}

void loop() {

}

Hello!
Connected!

I don't see any WiFi.begin(ssid,pwd) anywhere in your sketch?

Great observation. Why should WiFi.status() return WL_CONNECTED if ESP isn't really connected to a wifi network? In my opinion it's a bug, isn't it? I repeat: I erase Sketch and wifi settings each time I upload this sketch and if Wifi.config(...) function is commented out, WiFi.status() function doesn't return WL_CONNECTED. Suggestions?

Ok thank you. I searched the issue before opening this one but I didn't find it, my fault. Closing
