## Verified ESP8266 WiFi Event Behavior

**Test Setup:**  
- D1 Mini (ESP-12F)  
- Arduino Core 3.1.2  
- 50+ reboot cycles  

**Reliable:**  
✅ `onStationModeGotIP` (when stored statically)  

**Broken:**  
❌ `onStationModeDisconnected` (fails after 1st trigger/ESP.reboot)  

**Test Code:**  
## Verified ESP8266 WiFi Event Behavior

**Test Setup:**  
- D1 Mini (ESP-12F)  
- Arduino Core 3.1.2  
- 50+ reboot cycles  

**Reliable:**  
✅ `onStationModeGotIP` (when stored statically)  

**Broken:**  
❌ `onStationModeDisconnected` (fails after 1st trigger)  

**Full Test Code:**  
// ===== WiFi Event Handlers ===== //
void onConnected(const WiFiEventStationModeGotIP& event) {
  //Serial.println("WiFi connected!");
  Serial.printf("Wifi connected. IP: %s \n", WiFi.localIP().toString().c_str());
  setmDNS();
  digitalWrite(LED_BUILTIN, HIGH); // LED off (connected)
}

defined in setup() by:
static WiFiEventHandler onGotIPHandler = WiFi.onStationModeGotIP(&onConnected);

Do not rely on onStationModeDisconnected -> won't work on the second disconnection. 
Always use  while (WiFi.status() != WL_CONNECTED){
