Use a virtualpin to store values

FAQ

Hello,
I would like to know if it is possible to use a virtualpin not attached to a widget to store a value on the server and be able to retrieve it with virtualsync ??? or is there another way to do it ?
Thanks for your help

Yes this is possible. Write the value using Blynk.virtualWrite(Vpin, value);, and retrieve it using Blynk.syncVirtual(Vpin);, and its associated function.

int value;

BLYNK_WRITE(V2) {
  value = param.asInt(); 
}
