Hi,
I am using Arduino Mega (Arduino Version 1.8.9) and ESP8266 as wifi shield. Blynk is set up to read temperature measurements and also to take inputs which actuate servo valves. I have the ESP8266 core installed and libraries Blynk Library Master
Everything is working fine with the exception that the wifi connection will at times break down and I need get the arduino to automatically reconnect to wifi and Blynk. I read what I could find and believe to understand how to use " Blynk.connectWifi(ssid, pass);" and “Blynk.config(auth);” in the loop function to accomplish that.
My issue is the code does not even compile. It throws errors on the “Blynk.wifi” command such as error: ‘class BlynkWifi’ has no member named ‘connectWifi’ - as if it cannot find the correct library. However I do not see which library is missing. Feels to me as if I am overlooking sth obvious… Thanks for your help. Code and full error log below.

// Set ESP8266 baud rate
EspSerial.begin(ESP8266_BAUD);
delay(10);
// BLYNk
Blynk.begin(auth, wifi, ssid, pass);
timer.setInterval(2000L, myTimerEvent);
void loop() {
if (Blynk.connected()) {
Blynk.run();
}
else {
Blynk.connectWifi(ssid, pass);
if (WiFi.status() == WL_CONNECTED){
Blynk.config(auth);
Blynk.connect();
}
}
timer.run();
}
