Can someone save me some frustration and help me understand why the following code does not refresh the LCD properly? The Serial Monitor updates as expected; however, the LCD always displays "Connecting..." even though the LCD calls are in the same block as the Serial Monitor ones.
void wifiStatus(){
delay(4500);
long wifiStatus = WiFi.status();
long wifiSignal = WiFi.RSSI();
if (WiFi.status() != WL_CONNECTED) {
Serial.println("WiFi connection is down, trying to connect..");
lcd.setCursor(0, 0);
lcd.clear();
lcd.print("Connecting...");
WiFi.disconnect();
wifiConnect();
} else {
delay(500);
lcd.clear();
lcd.setCursor(0, 0);
lcd.print("Status:");
lcd.print(wifiStatus);
lcd.setCursor(0, 1);
lcd.print("Signal:");
lcd.print(wifiSignal);
Serial.print("WiFi Status: ");
Serial.print(wifiStatus);
Serial.print(" Signal: ");
Serial.print(wifiSignal);
Serial.println(" dBm");
}
}
The console correctly displays:
19:59:38.469 -> WiFi Status: 3 Signal: -79 dBm
19:59:43.570 -> WiFi Status: 3 Signal: -78 dBm
19:59:48.653 -> WiFi Status: 3 Signal: -79 dBm
