Hi
I’m using local server v0.41.0 and latest apps and latest Blynk library 0.5.4
My understanding is that it support up to 255 virtual pins; at least I can select them in my Blynk app.
However when I try to use Virtual Pins > 127 I get the following error when compiling. Is there something I’m missing ?
Blynk Library 0.5.4 is 2.5 months old whereas the App and Server references to this are newer… and I haven’t seen any reference to 255 vPins in any Blynk Library version notes, so it probably requires a newer library update (unreleased as of yet).
agree. I was thinking maybe there is a workaround / hack to enable it. I checked Blynkconfig.h but nothing obvious. I even tried incorporating:
#define BLYNK_USE_256_VPINS
in my sketch but that didn’t work either 
Found this… so yes, probably needs the full Blynk tribunal support (Server 
Apps (Beta only) Library… sooooon? )
:
i think you have answered it - thank you.
Perhaps there is a quick and easy hack that Blynk community knows about…
I know that “no, not yet” is not the answer you want to hear 
… but based on what little I have looked at (as indicated in a simple library search for the number 128), It would be neither quick or easy to go through and modify all the relative lines of code to account for pins 129-255… assuming that is all that would be needed 
But if you make it work, then great! let us know.
Eg. in Blynkhandlers.cpp alone…

Perhaps as “simple” as creating an additional #ifdef groups of code 
Don’t forget BlynkHandlers.h and other supporting files.
I don’t think he wants to wait

Virtual pins out of 0-127 range are be supported only via BLYNK_WRITE_DEFAULT() / BLYNK_READ_DEFAULT() API
https://docs.blynk.cc/#blynk-firmware-blynktimer-blynk_write_default
There are no plans to support more than 128 pins on fw level via “easy API”.
The docs are updated

I never figured out how to use more than one of those functions at a time anyhow 
And while this is @mars Topic… now I am curious… what does this have to do with when the official use of up to 255 virtual pins (using the normal functions) begin? Next Library release?

I had to hunt for this 
So for anyone curious…
Note: For virtual pins with numbers > 127, the V128 syntax is not available.
Please use plain virtual pin number, for example:
Blynk.virtualWrite(128, "abc");

Ah, OK… I think that is where the assumptions started… that it was just code as normal, but now with MOWR vPins 
thanks for that.
Just curious, is there a particular reason why
BLYNK_WRITE
is not supporting for vPIN > 127 ?
I tried
BLYNK_WRITE(V228) {
without
#define BLYNK_USE_256_VPINS
that runs too
