Compilation error of Blynk libs


I am getting Blynk libs compilation error I cannot resolve. Would be happy if somebody could take a look.

• Arduino Nano 33 BLE Sense + SERIAL over UART
• Blynk Library version: 0.6.1
• Add your sketch code.

#define BLYNK_PRINT Serial
UART SerialBLE(digitalPinToPinName(1), digitalPinToPinName(0), NC, NC);

#include <BlynkSimpleSerialBLE.h>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "YourAuthToken";

void setup()
  // Debug console

  Blynk.begin(SerialBLE, auth);

  Serial.println("Waiting for connections...");

void loop()
  // You can inject your own code or combine it with other sketches.
  // Check other examples on how to communicate with Blynk. Remember
  // to avoid delay() function!


Can’t get things compiled. I made new clean sketch, used some ready example code as I perform Blynk connection attempt only, included latest Blynk lib of version 0.6.1 and does not want to compile. What do I miss?
