I have been getting this error message several times now on my new Arduino Uno WiFi Rev2.
Here is my code below:
#include <Blynk.h>
#define speakerPin 11
/* Comment this out tBo disable prints and save space */
#define BLYNK_PRINT Serial
#include <SPI.h>
#include <WiFi.h>
#include <BlynkSimpleWifi.h>
// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "************************";
// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "***********";
char pass[] = "**********";
// Attach virtual serial terminal to Virtual Pin V1
WidgetTerminal terminal(V1);
// You can send commands from Terminal to your hardware. Just use
// the same Virtual Pin as your Terminal Widget
BLYNK_WRITE(V1)
{
// if you type "Marco" into Terminal Widget - it will respond: "Polo:"
if (String("Marco") == param.asStr()) {
terminal.println("You said: 'Marco'") ;
terminal.println("I said: 'Polo'") ;
} else {
// Send it back
terminal.print("You said:");
terminal.write(param.getBuffer(), param.getLength());
terminal.println();
}
// Ensure everything is sent
terminal.flush();
{
}
void setup();
pinMode(11, OUTPUT);
{
// Debug console
Serial.begin(9600);
Blynk.begin(auth, ssid, pass);
// You can also specify server:
//Blynk.begin(auth, ssid, pass, "blynk-cloud.com", 80);
//Blynk.begin(auth, ssid, pass, IPAddress(192,168,1,100), 8080);
// Clear the terminal content
terminal.clear();
// This will print Blynk Software version to the Terminal Widget when
// your hardware gets connected to Blynk Server
terminal.println(F("Blynk v" BLYNK_VERSION ": Device started"));
terminal.println(F("-------------"));
terminal.println(F("Type 'Marco' and get a reply, or type"));
terminal.println(F("anything else and get it printed back."));
terminal.flush();
}
}
void loop(){
Blynk.run();
while(terminal, 1){
tone (speakerPin, 100);
}
}
And here are the error messages:

This report would have more information with

option enabled in File -> Preferences.
All help is greatly appreciated. Thank you!
