ESP32 Board Manager on Android App

I am currently trying out an ESP32 board and running a simple RGB LED for an example on a Blynk Local server.

It seems that I can only see virtual pins on this board in the Android App when trying to use zeRGBa or the slider. I tried this on the Blynk servers and an iphone as well with the same result. I switched to ESP8266 boards and was able to make the LED operate by finding the right pin map.

• Hardware model: ESP32 Dev Board
• Smartphone Android + 10
• Blynk local server


#define BLYNK_PRINT Serial

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

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

// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "xxxxxx";
char pass[] = "xxxxxx";

void setup()
  // Debug console
  Blynk.begin(auth, ssid, pass, IPAddress(192,xxx,xx,xx), 8080);

void loop()

@luchinit please edit your post, using the pencil icon at the bottom, and add triple backticks at the beginning and end of your code so that it displays correctly.
Triple backticks look like this:


Thanks, should be fixed.

What board type have you selected in the app?


Esp32 Dev Board

Personally, I’d always use virtual pins with these widgets, but I can confirm that the iOS version of the app is the same - only virtual pins are available with the ESP32 Dev Board, not digital.


Thanks Pete, I’ll play around with virtual pins in the meantime and learn how those work.
