Hi, I have a problem sending a string.
it is a timer.
Blynk.virtualWrite(V6, horas , “:” , minutos , “:” , segundos);
I send this plot on android it works perfect, but on iphone it doesn’t.
Could you help me I use Blynk 2.0.
@Eugene one for you to look at?
@neurona have you tried building the string first, using a temporary string variable, then sending that in your Blynk.virtualWrite command?
What type of widget are you sending this string to?
Pete.
You might want to look at the sprintf command to give you HH:MM:SS format.
Pete.
thanks Pete if I was watching it but I don’t need it that’s fine. Thank you

}here it is used to adjust the utc time.
I’m not a programmer I just understand a little Pete.
