This is the weirdest thing…I have created a Button widget with a Numeric Input widget. The Numeric Input widget settings are 0 - 3 in 0.01 steps. The code comes from Gunner. The function og these 2 Widgets is as follows switch button off adjust the numeric input switch on the button numeric input is locked. I have created 2 identical set of this so 2 buttons 2 numeric inputs. all works fine but at reboot 1 set always resets itself to 0. the other does not. And i mean they are identical (copies)
Any explanations as to why?
BLYNK_WRITE(V91)
{
if (PH4Butt == 1)
{
Blynk.virtualWrite(V91, Cal_4);
}
else
{
Cal_4 = param.asFloat();
}
}
BLYNK_WRITE(V92)
{
if (PH7Butt == 1)
{
Blynk.virtualWrite(V92, Cal_7);
}
else
{
Cal_7 = param.asFloat();
}
}
BLYNK_WRITE(V58)
{
PH7Butt = param.asInt();
}
BLYNK_WRITE(V78)
{
PH4Butt = param.asInt();
}
Any other virtual writes in your app to V91 or V92? Or any sync functions?
I will try changing Vpins
Nope same thing. 1 set Ok, 1 set zeros out at boot up. I allocated Vpins from 100 onwards as I know they are not allocated.
What happens if you create another copy? If that works OK then try removing the one that doesn’t and see if that passes onto another etc etc. It may be that it only affects this first created or last created etc
I am not sure wht it happens though. Maybe you could call a virtualSync(V91), virtualSync(V92) etc in BLYNK_CONNECTED function to get the previous values?
Ok I have figured out the cause. Its Blynk.syncAll(); The problem is I need this statement as part of the entire project.

Probably better to just sync the pins you need.
Pete.
There are over 60 of them!!!
60 where you need to pull back the current values from the server and assign them to variables in your code?
If that is the case then do them individually in batches of 5 or 10.

OMG!!! the thought of typing all those numbers!!! Well its the only solution thanks.

That was referring to the test sketch version. I always just do small test sketch instead of messing with the larger code.
Ah OK, that doesn’t help when trying to diagnose problems though 
At least you found it, no worries 
@JustBertC is this what you mean in BLYNK_CONNECTED?
for (int Vpin = 0; Vpin <= 91; Vpin++)
Blynk.syncVirtual(Vpin);

As I said earlier, I’d do them in batches - say 10 at a time, otherwise you could run into the same issues as using sync all.
I’m still not convinced that you really need yo sync 91 virtual pins though.

To my way of thinking, that’s just poor programming.
Pete.
??? How can you say that when you don’t know the entire project? Or what it is I have made?
