Virtual pin V13

I need to use 13 virtual pins for an application.
It’s possible?


More information required!

  1. Add details :
    • Hardware model + communication type. For example: Arduino UNO with Ethernet Shield
    • Smartphone OS (iOS or Android) + version
    • Blynk server or local server
    • Blynk Library version


• ESP32 Dev Board (WiFi)
• Smartphone iOS 12.5.4
• Blynk server: Blynk Cloud
• Blynk Library version 2.26.7 (1)


Im using 13 virtual pins for a project, and all of them are working. Not sure about that library version , most probably the last one. Same board and server.

That’s the app version, not the library version. You’re using Legacy Blynk (Blynk 0.1) so you should be using library version 0.6.1

If you’ve chosen ESP32 as your device type then you should have 256 virtual pins available.
I’m guessing that you don’t understand that there is no link between virtual pins and physical pins on your board?

You should probably read this:


Ok! thank you
