Blynk2.0 raspberry pi No Auth Token

I’m sorry about my English is a little strange. Because I’m Japanese.

I have a problem about Auth Token.
I made a Templates at Blynk. Cloud. Like this↓

But there ain’t Auth Token.

So I can’t connect my device raspberry pi
How should I do?

You are looking at the Template screen.

Go to the Devices screen (Magnifying Glass icon at the top) and create a device from your template.
You will then get an auth token for your device.


I can find it!!
Thank you very much!!!

I’m surprised at we can’t use wifi to connect RPi and Blynk 2.0.

I don’t have Blynk 1 account.

Is there other way to connect RPi and Blynk 2.0.

I’ve moved your new topic into your old one, as they seem to be related.

What programming language/Blynk Library are you attempting to use to connect your Pi to Blynk IoT?


Thank you for moving it.

I use C++
Because Blynk Code use C++

To run C++ on the Pi you need a C++ interpreter on the Pi. The solution to this was to use WiringPi, but WiringPi was deprecated in 2019.

Is there a reason why you’re using the Pi?


I will try ESP32!!!

Thank you for teaching me.

#define BLYNK_DEVICE_NAME “~<s>"
#define BLYNK_AUTH_TOKEN "</s>~”

// Comment this out to disable prints and save space
#define BLYNK_PRINT Serial

#include <WiFi.h>
#include <WiFiClient.h>
#include <BlynkSimpleEsp32.h>

char auth[] = BLYNK_AUTH_TOKEN;

char ssid[] = “~<s>";
char pass[] = "</s>~”;

WidgetLED led1(V0);

BlynkTimer timer;

void blinkLedWidget()
if (led1.getValue()) {;
Serial.println(“LED on V0: off”);
} else {
Serial.println(“LED on V0: on”);

void setup()


Blynk.begin(auth, ssid, pass);

timer.setInterval(1000L, blinkLedWidget);

void loop()

I compiled this code.
And I wanna make the LED shine.
use blynk2.0 & esp32

I checked esp32 and my Ipone conected WiFi

but LED isn’t shine.
Only my blynk V0 button in my iphone Alternately glow

what sould i do

@TouiKaitoJP please edit your post and add triple backticks ( ``` ) before and after your sketch.

Make sure the led is not broken, and led connection polarity must be strictly observed.

You are supposed to have an LED widget attached to V0, not a Button widget.
